Start Battery
12V 90Ah LiFePo4 Deep Cycle Battery
-
Our start-stop battery can be discharged to a depth of 80% DOD and supports long periods of high current discharge. The voltage is stable and saves fuel consumption. Long cycle life and no need for replacement for the life of the vehicle.
|
BSLBATT® batteries are based on Lithium iron battery technology (LiFePO4). Compared to lead-acid alternatives, this 12V90Ah 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.
