SL4580W • 12.8V 135Ah Slimline Lithium LiFePO4 Battery

SL4580W • 12.8V 135Ah Slimline Lithium LiFePO4 Battery, these slimline lithium (LiFePO4) batteries are for situations where space is at a premium these compact mountable batteries measure just 65mm high and weigh just 17 kg. Each is fitted with 100A Anderson input and output plugs for easy connection to your equipment or solar charger output. Each utilises the same battery management system found in the standard LiFePO4 battery series for safe operation at all times, plus a handy voltage & capacity readout.


About LiFePO4.

The latest generation in maintenance free batteries is here! LiFePO4 batteries offer longer service life than traditional lead acid batteries, plus weigh less than HALF as much as SLA batteries. LiFePO4 also provide more usable life per cycle, allowing for longer run times by holding a higher voltage until capacity is almost exhausted. These batteries will also maintain 80-90% charge when in storage – far higher than their lead acid counterparts.   Each battery is fitted with an internal battery management system to provide safe charging and discharging at all times. This system provides internal short circuit, over temperature and under/over voltage cut off.
