Product Details

You don't have to carry a bulky, heavy battery to power your camping adventures anymore. Meet VoltX 12V 100Ah LiFePO4 Lithium Battery, Outbax's slimmest lithium battery for sale. You'd easily spot this one because of its ultra-slim design but don't let it fool you—this battery pack is built to provide you with a reliable and steady power source for all your travelling needs.

Made up of prismatic cells for quality power output, it contains a total of 36 batteries in the matrix encased in a heavy-duty case. It's also backed by a built-in battery management system that all LiFEPO4 batteries have. This allows for a maintenance-free operation, as the BMS constantly monitors every cell to ensure the battery is always optimised for best performance.

Our VoltX slimline battery is also a win in lifespan and safety. You get more than 2000 cycles that last for up to 7 years so there's no need to constantly replace your battery. Best of all, LiFEPO4 is considered the safest battery in the market due to its non-toxic component and incombustible feature, so you have one less thing to worry about while using it.
