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. Can be wired in series and/or parallel.
5 Year Warranty
This 12V 150Ah LiFePO4 replacement battery is compatible in size with traditional 150Ah SLA batteries, but with all the benefits of cutting edge lithium technology. 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. This will replace 300amps of AGM battery.
These batteries will also maintain 80-90% charge when in storage - far higher than their lead acid counterparts. The latest generation in maintenance free batteries is here!
Dimensions: 521 x 237 x 217mm
Overall Weight: 20kg
