Frequently Asked Questions

Below You Will Find The Answers To The Questions We Get Asked The Most On BSLBATT And Lithium Batteries.

Lithium batteries are rechargeable batteries in which lithium ions move from the anode to the cathode during discharging and back when charging. They are popular batteries for use in consumer electronics because they provide high energy density, possess no memory effect and have a slow loss of charge when not in use. These batteries come in a wide variety of shapes and sizes. Compared to lead-acid batteries, Lithium batteries are lighter and provide a higher open circuit voltage, which allows for power transfer at lower currents. These batteries have the following characteristics:

 

● Features of BSLBATT Lithium Batteries:

 

● Lightweight, up to 80% less than a conventional, comparable energy storage lead-acid battery.

 

● Lasts 300-400% longer than lead-acid.

The term “Lithium-ion” battery is a general term. There are many different chemistries for lithium-ion batteries including LiCoO2 (cylindrical cell), LiPo, and LiFePO4 (cylindrical/prismatic cell). BSLBATT mostly focuses on designing, manufacturing, and marketing LiFePO4 batteries for its Solar and Motive Power batteries.

Disadvantages of Nickel

 

Cadmium (NiCd) includes:


● High rate of self-discharge


● Cadmium is highly toxic


● Environmental recycling issues


● Memory effect is one of the biggest disadvantages of using NiCd

 

Commonly used in starter batteries for internal combustion engine (ICE) vehicles Lead Acid is normally a low-cost secondary battery, composed of a lead-dioxide cathode, a sponge metallic lead anode, and a sulphuric acid solution electrolyte. The heavy metal element makes lead-acid batteries toxic and improper disposal can be hazardous to the environment.

Side effects of Nickel Metal Hydride (NiMH) batteries include:

 

● Poor charge retention

 

● Memory effect

 

● Insufficient and decreasing operating time

 

● Short battery life

 

● High rate of self-discharge

 

Disadvantages of lead-acid batteries include:

 

● Failure between several hundred and 2,000 cycles


● Comparatively low energy density


● Long charge time


● Careful maintenance requirements

When not in use Sodium (Na-NiCl2) batteries typically require to be left on the charge, in order to be available for use when needed.

 

If shut down, the reheating process lasts 24 hours, and then a normal charge process of 6-8 hours is required for a full charge. Inefficiency due to energy consumption when not in use.

Lithium Iron Phosphate (LiFePO4) batteries are a type of lithium battery that provide several advantages over traditional lithium-ion batteries based on LiCoO2 chemistry. LiFePO4 batteries provide much higher specific capacity, superior thermal and chemical stability, enhance safety, improved cost performance, enhanced charge, and discharge rates, and enhanced cycle life, and come in a compact, lightweight package. LiFePO4 batteries offer a cycle life of over 6,000 charge cycles!

 

All of the Lithium batteries that BSLBATT sells are LiFePO4 batteries.

As with any battery replacement, you need to consider your capacity, power, and size requirements, as well as making sure you have the right charger. Keep in mind, when upgrading from lead-acid to LiFePO4, you may be able to downsize your battery (in some cases up to 50%) and keep the same runtime. Most existing charging sources are compatible with our lithium-iron phosphate batteries. Please contact BSLBATT technical support if you need assistance with your upgrade and they will be happy to make sure you pick the right battery.

BMS stands for Battery Management System. The BMS protects the cells from getting damaged — most commonly from over or under-voltage, over-current, high-temperature, or external short-circuiting. The BMS will shut off the battery to protect the cells from unsafe operating conditions. All BSLBATT batteries have a built-in BMS to manage and protect them against these types of issues.

Battery life is measured in life cycles and BSLBATT’s LiFePO4 is typically rated to deliver 3500 cycles at 100% depth of discharge (DOD). Actual life expectancy is dependent on several variables based on your specific application. If used for the same application, a LiFePO4 battery can last up to 10X longer than a lead-acid battery.

Phosphate-based batteries offer superior chemical and mechanical structure that does not overheat to unsafe levels. Thus, providing an increase in safety over lithium-ion batteries made with other cathode materials. This is because the charged and uncharged states of LiFePO4 are physically similar and highly robust, which lets the ions remain stable during the oxygen flux that happens alongside charge cycles or possible malfunctions. Overall, the iron phosphate-oxide bond is stronger than the cobalt-oxide bond, so when the battery is overcharged or subject to physical damage then the phosphate-oxide bond remains structurally stable; whereas in other lithium chemistries the bonds begin breaking down and releasing excessive heat, which eventually leads to thermal Runaway. Lithium phosphate cells are incombustible, which is an important feature in the event of mishandling during charging or discharging. They can also withstand harsh conditions, be it freezing cold, scorching heat or rough terrain. When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm. If you’re selecting a lithium battery and anticipate use in hazardous or unstable environments, LiFePO4 is likely your best choice. It’s also worth mentioning, LiFePO4 batteries are non-toxic, non-contaminating and contain no rare earth metals, making them an environmentally conscious choice.

Simply charge your battery to 28.8 volts, disconnect the battery from your charger, and your equipment, then store in temperatures anywhere between 23°F to 95°F (-5°C to 35°C). For storage longer than 3 months, the recommended temperature range is 32°F to 77°F (0°C to 25°C), then it’s safe to store at a 50% state of charge. Unlike lead-acid batteries, a partial state of charge does not harm lithium batteries.

Yes, because there is no fluid inside of LiFePO4 batteries. This gives you the flexibility to install the battery where it is best suited for your application.

Batteries or Product

There is so much information to learn about LiFePO4 technology and the benefits of switching from lead-acid to lithium. Embrace green energy and get answers to your LiFePO4 frequently asked questions below.

Typically, LiFePO4 batteries are about a quarter of the weight of lead-acid batteries. What does this mean for your LiFePO4 battery applications? You aren’t weighed down by heavy lead-acid batteries, allowing your vehicles to run at a higher speed and with more efficiency.

LiFePO4 batteries are both durable and safe for use in vehicles from golf carts to yachts. Built-in safety features prevent your battery from overheating by shutting it down when temperatures rise too high. Most lead-acid batteries lack this mechanism, putting your battery at risk of catching fire.

LiFePO4 batteries are customizable for your energy needs, making it easy to switch from lead-acid batteries, regardless of the type of vehicle.

LiFePO4 battery life is 10 times longer than that of a lead-acid alternative. Even when charging and draining LiFePO4 batteries once each day, LiFePO4 technology offers more than 13 years of life, while the competition lasts less than two years.

BSLBATT® batteries area unit ordinarily used for Industrial Applications, Energy Storage Systems (ESS), Golf Cart applications, Marine Applications, RV, Trailer & Camper, Floor Machines, etc. BSLBATT® Battery is used for any system or application that will unremarkably use a Lead-acid battery (AGM, GEL) in 12V, up to 48V. After removing your previous batteries, place the BSLBATT® battery within the same means. you will use equivalent cables to reconnect the BSLBATT® battery.

BSLBATT® lithium-ion 12V or 48V batteries may be partly charged or discharged in contrast to Lead Acid batteries that must be absolutely charged when using or before storage. as an example, you’ll leave your battery 0.5 charged for a few weeks with no issue.

 

If you propose to store the battery for a protracted amount (> a pair of months), you would like to charge the battery at minimum twenty-fifth of SoC (State of Charge) before storage. it’s necessary to examine battery voltage every six months throughout storage.

BSLBATT® Lithium-ion technology uses the most recent and most advanced intrinsic battery management system (BMS) to watch and stop injury to the battery throughout use. you will utilize a Lead-acid charger with a BSLBATT® Lithium battery, however, some customers prefer employing a Lithium charger to stay a much better life.

 

Several charging sources area unit possible:

 

● Alternator: Most alternators (marine, RV, cars) can efficiently charge BSLBATT® lithium-ion technology as before long generator charge voltage is between fourteen.0V and 14.6V (for a 12V battery)

 

● Conventional lead-acid accumulator charger: BSLBATT® Battery Management System (BMS) is intended to be compatible with customary chargers. you would like to ascertain that the charger encompasses the inherent CC/CV charge algorithmic rule (Constant Current / Constant Voltage) and the charger’s most voltage is comprised between fourteen.0V and 14.6V (for a 12V battery)

 

● Lithium-Ion charger: this can be the simplest thanks to charging BSLBATT® Lithium-ion battery. These chargers embed some dedicated charge algorithmic rules with precise charge voltage. It conjointly manages with efficiency charge floating voltage and period so as to maximize battery life.

LiFePO4 batteries are easily recyclable, and since they only need to be replaced about once a decade, you’re cutting down on waste produced. LiFePO4 technology is compatible with solar applications, and you may also choose to buy a battery made from recycled material.

BSLBATT® advanced lithium-ion technology can give you 3000 complete charge and discharge cycles at eightieth DoD (Depth of Discharge). once 3000 cycles, you may still have over eightieth of usable energy left. just in case you discharge BSLBATT® at the sixty-fifth DoD rate, you’ll be able to expect to urge 5000 cycles.

 

● Example 1: One BSLBATT® 12V-100Ah battery, once being discharged at eightieth DoD for 3000 cycles, is currently a 12v 80ah battery.

 

● Example 2: One BSLBATT® 12V-100Ah, once being discharged at sixty-fifth DoD for 5000 cycles, is currently conjointly a 12v 80ah battery.

 

In terms of your time period, If you discharge eightieth of the BSLBATT® and so recharge it on a daily basis, seven days every week for eight years, you may still have eightieth of usable battery energy left. this can be an outsized increase in a period of time compared to a traditional Lead Acid battery (AGM, Gel) rated at five hundred cycles for five hundredth DoD cycles.

LiFePO4 technology offers 100 percent charging efficiency, drastically reducing the amount of time you must wait for your battery to charge. Lead-acid batteries average a charging efficiency of 85 percent. Unlike lead-acid batteries, lithium doesn’t need to go through the time-consuming absorption phase, which provides the final 20 percent of power during charging. Lithium receives a full charge in a fraction of the time.

Unfortunately, lead-acid batteries deteriorate unless you charge them every day. Lithium maintains most of its usable capacity even if you store it without charging for a year. For optimal protection, experts recommend storing LiFePO4 batteries at 50 percent depth of discharge (DOD).

The short answer is virtually none. While lead-acid batteries must go through routine saturating charges lasting 14 hours or longer, LiFePO4 technology maintains consistent power even if you only charge it partially. However, extreme temperatures may damage your battery, and you should take care to charge it at the right voltage. 14.6 V is the recommended charging voltage.

Each BSLBATT® embeds an inherent BMS. This BMS could be an advanced style that manages 2 main aspects of the battery throughout operation :

 

Protection options :

 

● Low Voltage Protection Switch – mechanically disconnects at ten.0V

 

● Over Voltage Protection Switch – mechanically disconnects at fourteen.8V

 

● Short Circuit Protection Switch – mechanically and safely disconnects the battery

 

● Reverse Polarity Protection Switch – mechanically and safely disconnects the battery

 

● Over-temperature – mechanically shut-down battery till traditional temperature recovery

 

Balancing options :

 

● Internal cell reconciliation – mechanically balances BSLBATT® cells throughout battery operation. reconciliation algorithmic rule has been developed to confirm excellent balance between cells throughout battery life.

 

● Charge reconciliation – for BSLBATT® connected in parallel and/or nonparallel,  the BMS can balance 

every BSLBATT® severally, so as to produce a perpetually balanced battery system.

The BSLBATT® merchandise is designed around AN assembly of sealed cells. there’s no risk of a solution leak. the full of block cells and embarked natural philosophy are firmly fastened within the battery casing.


All our batteries may be placed in any position (tilted or lying). there’s no obligation to put in the upright, as for the standard batteries in Lead/AGM.

Among all the environmental elements, temperature has the biggest effect on battery performance. The electrochemical reaction on the electrode/electrolyte interface is connected to the temperature. The electrode/electrolyte interface is considered the heart of the battery.

 

● If the temperature gets lower, the reaction rate of the electrode also gets lower.

 

● If the battery voltage keeps invariable, the discharge current becomes lower, and also the power output will be reduced.

 

● If the temperature goes up, the condition is reversed. That is, the battery’s power output will increase.

 

● The temperature will also affect the speed of the transmission of the electrolyte.

 

● If the temperature goes up, the speed of transmission will be faster.

 

● If the temperature goes down, the speed of transmission will be slower.

BSLBATT lithium batteries are manufactured with the safest lithium chemistry, lithium iron phosphate (LiFePO4). LiFePO4 batteries are best known for their strong safety profile, the result of extremely stable chemistry. However, to make sure the batteries stay within their safety specifications and ensure they cannot be damaged, they have an internal battery management system (BMS). A BMS makes sure each cell in the battery remains within safe limits. A well-designed battery management system can help maximize lifetime, and ensure safe operation over a wide range of conditions.

Charging and Discharging

Frequently Asked Questions

BSLBATT batteries can be charged with most alternators. Depending on the quality of the alternator, it should work with LiFePO4 batteries. Low quality alternators with poor voltage regulation can cause the BMS to disconnect LiFePO4 batteries. If the BMS disconnects the batteries, the alternator could be damaged. To protect your LiFePO4 battery and alternator please be sure to use a compatible high-quality alternator or install a voltage regulator. Please contact BSLBATT technical support if you need assistance.

Lithium iron phosphate batteries can be charged in as fast as 1 hour. We recommend using a rate that charges our batteries in 2-5 hours. Please refer to the datasheet for your particular model, to find the recommended charge rates. All of our data sheets are available on our website within the product section.

The short answer is “not very.” Our specs call for the batteries to be recharged to 14 to 14.6 volts for bulk charging, and to float the battery at 13.8 volts. If you recharge the battery below that range, you’ll have less than 100% charge in the battery – it will be at a partial state of charge. All that means is you’ll need to recharge it again sooner than you otherwise would. But you’re not harming the battery in any way by coming in lower than our recommended range – you’re only cutting into the capacity you’ll have from that charge. If you go over the 14.6 volt limit, our battery monitoring system – or BMS – will sense the over-voltage and disconnect from the battery. That’s it! The only thing that will happen is that the BMS will do what it is designed to do and protect your battery.

No! Drawing current from a lithium battery does not produce any harmful or undesirable byproducts. Charging and recharging simply moves lithium ions from one side of a membrane to another. Lithium batteries also have their peak performance when they spend their life at a partial state of charge. The ideal maximum charge for a lithium-ion battery is about 80-90%. This is much more practical in terms of the time and amperage necessary to recharge your battery, and it gives you a margin of error for when things don’t go as planned.

LiFePO4 batteries can be discharged up to 100% without risk of damage. Make sure you charge your battery immediately after discharge. We recommend discharging be limited to 80-90% depth of discharge (DOD) to avoid the BMS disconnecting the battery.

The rate of discharge for LiFePO4 batteries has virtually no effect on the delivered capacity. This is not the case with lead-acid batteries which have significantly reduced capacity of up to 50% as the rate of discharge increases.

Regenerative currents are currents that are provided to the battery like a charge current during breaking and/or for speed control. BSLBATT batteries are unlike other lithium batteries in that they have the ability to manage these regen currents when they occur. BSLBATT batteries are built with intuitive software to manage this, avoiding disconnects that occur in these scenarios

Let’s first start with some basics about your golf cart motor. Electric motors are reversible machines, they can function as motors or as generators. In fact, while your motor is operating, it is the generator effect that produces the Counter Electromotive Force (CEMF), which reduces the current into the motor. Without this effect, the currents in the motor would be too large to manage. An additional advantage of the CEMF is that it can be used to send energy back to the source. The typical situation is one of an electric vehicle rolling on a sharp downhill slope and forcing the motor to turn fast enough to engage the regenerative braking, which sends energy to the batteries. If your battery’s BMS isn’t built to handle regen currents, when this occurs your battery will simply disconnect resulting in a sudden stop, which can be concerning. The good news is our BSLBATT batteries feature intuitive software that tells the BMS to manage these regen currents when they occur. This is quite unique in the lithium battery world today, making BSLBATT Battery truly different from other lithium batteries.
