12V 200Ah Lithium Iron Phosphate Battery (LiFePO4, M8)

This 12V 200Ah lithium battery (LiFePO4 chemistry) is compatible in size with traditional 200Ah 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. 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!

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. When used in series each battery will need to be discharged to cut off before connecting so that all cells are all balanced.

Factory supplied at 30% charge for safety compliance. Must be charged fully before use.


Excessive temperatures over 65ºC can effect the ABS housing. Need to be well ventilated in warm conditions. Not for use in engine bays.
