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.
Taking Charge of Your Power Requirements
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.
To lengthen the life of your 105SMART5, their innovative internal Battery Management System (BMS) with Active Balancing has been exclusively developed for Roamer to support high power off-grid living. And Roamer back everything with a 12 year warranty, because that’s how much they believe in our product.
Maintaining excellent balance throughout its 15 year life expectancy, the Roamer 105SMART5 delivers stable, high power with each and every cycle.
