The KickAss 12V 120Ah Lithium Compact Deep Cycle Battery is the entry point into lithium, a full 120Ah of usable capacity in a case measuring 238 x 168 x 258mm, noticeably smaller than a traditional N70. At 12.55kg it is roughly a third the weight of the AGM equivalent.

120Ah Compact LiFePO4 Deep Cycle Battery

All 120Ah is usable. AGM batteries are limited to about half their rated capacity before you start damaging them, so a 120Ah lithium does the work of a 240Ah AGM in a fraction of the space and weight. 120A continuous charge and discharge means it will run a fridge and an inverter while also accepting a high charge current for faster recharge on the road. A-grade prismatic cells with an integrated BMS protecting against overcharge, over-discharge, short circuit and temperature extremes, in a heavy-duty plastic case rated IP65.
