BSLBATT® batteries are based on Lithium iron battery technology (LiFePO4). Compared to lead-acid alternatives, this 12.8V100Ah battery is the perfect combination of size and capacity to fit many applications including, RV, marine, solar energy systems and more.it's a lightweight alternative to lead-acid and one of our most popular lithium batteries.

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.
