QSL12100 12.8V 100Ah LiFePO4 Battery
QSL12100 12.8V 100Ah LiFePO4 Battery
The QSL12100 is a 12.8V 100Ah LiFePO4 (lithium iron phosphate) deep-cycle battery that replaces lead-acid batteries in RVs, marine, solar and off-grid systems, delivering 1.28kWh of energy in a maintenance-free, IP67-rated package.
Built with Grade A LiFePO4 cells and a smart BMS (50A/100A/150A/200A optional), it delivers over 6,000 charge cycles at 80% depth of discharge, roughly 5x the cycle life of lead-acid, with a stable 10-14.6V working voltage and 100A continuous discharge.
