Due to continuous improvements to our products, product may vary slightly from depiction.
Lower cost per cycle, greater than ten times the cycle life of
sealed lead-acid batteries
Ultra-light weight; Significantly lighter than sealed lead-acid batteries
Drop in replacement for sealed lead-acid batteries
Can use the same charger as sealed lea-acid batteries in most cases
(limited to a voltage of 7.3 volts)
Faster charging as a result of higher charge current
More usable capacity - sealed lead-acid battery capacity decreases as
discharge current increases
Includes Battery Management System (BMS) protection. Contains a
circuit that fully protects itself with a Low Voltage Disconnect and a
High Current Disconnect on discharge
Balancing circuit on charge
Advantages of LFP Over SLA
