The EP12100 is a 12V, 100Ah LiFePO4 (lithium iron phosphate) battery from Expert Power. It uses prismatic cells, which pack densely and make efficient use of space. This suits higher-capacity needs and integration into battery systems.
An integrated battery management system (BMS) provides fault protection and cell balancing. The cells deliver stable voltage and high power output.
Batteries can be connected in series for more voltage or in parallel for more capacity, so you can build larger battery banks. It works with Expert Power chargers and solar systems. Uses include trolling motors, DIY solar projects, RVs and campers.
