This 12.8V 100Ah lithium battery (LiFePO4) is compatible in size with traditional 90-100Ah SLA batteries (check dimensions), 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. Regardless of your wiring configuration it is technically best to individually charge each battery to 100% capacity using the same charger before connecting them. This ensures all batteries are at the same terminal voltage and will charge/discharge evenly.

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

Suitable for recharging with the mains battery charger models listed in the accessories below.

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

Important Note for Users Connecting This Battery In Series.
Due to a supplier error the shipping box and battery label is marked showing that this battery is not suitable for in series wiring. This is incorrect. The battery IS suitable for series wiring between 12-48V DC, up to 4 units. We apologise for any confusion.

IMPORTANT NOTE: A fixed installation of this battery in a recreational vehicle such as a caravan, camper or 4WD must adhere to Australian Standard AS/NZS 3001:2. We recommend all customers familiarise themselves with the standards requirements before using these batteries in fixed installations of this type. A professional installer should be consulted when a fixed battery installation is required in a recreational vehicle.
