Lithium Iron Phosphate (LiFePO4) Battery
12.8V, 12AH/10A BMS
Lighter Weight: About 40% of the weight of a comparable lead acid battery. A 'drop
in' replacement for lead acid batteries.
Higher Power: Delivers twice power of lead acid battery, even high discharge rate,
while maintaining high energy capacity.
Wider Temperature Range: -20 C~60 C.
Superior Safety: Lithium Iron Phosphate chemistry eliminates
the risk of explosion or combustion due to high impact, overcharging or short circuit
situation.
Increased Flexibility: Modular design enables deployment of up to
four batteries in series and max 20 batteries in parallel.
Application
Electric vehicles,Boats,Caravan,
electric mobility Solar/wind energy
Medical equipment
Lighting, etc.
