Roamer 105SMART5 MAX 12V 105Ah LiFePO4 Lithium Leisure Battery

Roamer 105SMART5 MAX 12V 105Ah LiFePO4 Lithium Leisure Battery

Compact power meets versatility with the Roamer 105SMART5. The upgraded 105Ah model (available from February 2026) features a brand new and exclusive MAX LiFePO4 cell, allowing this little powerhouse to safely charge at 2.2C (230A) and discharge at 3.0C (315A). This makes it by far the most powerful small lithium battery on the market and the only battery of its size capable of running a 3000W inverter.

This handbag-sized monster comes with all the same premium SMART5 features of it's larger siblings including Bluetooth, Active Balancing and CANbus integration.

Drop in to Get Outdoors

The Roamer 105SMART5 offers the most usable capacity of any battery in its size. If you’re swapping out an old 90-100Ah battery, then chances are your 105SMART5 will drop straight in without needing to modify existing brackets or spacers. And because it can be installed in any orientation, it fits comfortably under a seat, in a side cupboard, or behind the wheel arch.

The upgraded BMS actively balances all internal cells and supports installation of up to sixteen 105SMART5 batteries in parallel. It provides a complete range of protections including low temperature charging.

Each Roamer 105SMART5 is crafted using the highest quality matched and traceable Grade A cells and comes assembled with precision-engineered brackets, double-bolted cell connections, flexible copper busbars and an IP65 waterproof case.

And Roamer back everything with a 12 year warranty, because that’s how much they believe in our product.
