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.

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.

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 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.

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.

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 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.
