Group 31 Lithium Batteries – 1/2 the Weight, 2X the Power

BSLBATT Lithium Battery now has a commercial/industrial Group 31 lithium battery that combines high cranking power and high capacity in a single battery. This 24.5-pound lithium battery replaces a 75-pound lead battery, has serious cranking power & has more usable power while lasting 8-10 times longer. This “all in one” solution can be used for starting (nearly double the cranking power of the best AGM batteries) and “deep cycle” power supply applications in a variety of vehicles (10 times the cycles of lead batteries including premium AGM) and in some cases require fewer lithium batteries to do the job of lead batteries.

Group 31 Lithium Batteries

BSLBATT Lithium batteries charge FIVE times faster than lead and are more efficient when charged by solar panels and also don’t self-discharge. If there is no draw on the battery, it will still be at 50% state of charge and still at 13 volts after sitting for FIVE years, just give it a top of charge and it’s still within the spec of new! Perfect upgrade for 18-wheelers, car transporters, lift gates, emergency vehicles, marine, and other applications where a Group 31 battery is utilized.

Longer runtime = more recreation time with the B-LFP12-100. This 12V 100Ah deep cycle lithium battery is the perfect replacement for a group 31 AGM, GEL, or lead-acid battery. Weighing in at only 24.5 lbs it’s a lightweight alternative to lead-acid and one of our most popular lithium batteries.

BSLBATT lithium batteries provide more energy for high consumption than traditional lead-acid batteries. They also offer ultra-fast charging and discharging, high efficiency, and longer cycle life – plus no maintenance!

WARRANTY: 5 YEARS – 3 Years Free Replacement, 4th year 75%, and 5th year 50% Pro-rated and BSLBATT Lithium batteries have the lowest failure rate on the market.

1. The battery cover is sealed by bolts, so easy and convenient to open the cover to replace the battery cells and BMS.

2. There will have two LCD screens on the top of the battery cover showing some battery information: 1. Voltage 2. Capacity 3. Status 4. Current 5. Temperature 6. Time.

3. It also can have Bluetooth.

4. The BMS has low-temperature cut-off protection, which means that when people charge the battery below 0°C, the BMS will automatically cut off and stop charging.
