Drop in to get outdoors
The Roamer 160SMART3 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 160SMART3 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 four 160SMART3 batteries in series or parallel. It provides a complete range of protections including low temperature charging.
Taking charge of your power requirements
Each Roamer 160SMART3 is crafted using the highest quality matched Grade A+ cells and comes assembled with precision-engineered brackets, laser-welded cell connections, flexible copper busbars and an IP65 waterproof case.
To lengthen the life of your 160SMART3, our innovative internal Battery Management System (BMS) with Active Balancing has been exclusively developed for Roamer to support high power off-grid living. And we back everything with a 10 year warranty - because that’s how much we believe in our product.

“Fantastic service from start to finish and the post sale backup is second to none.”
Here at Roamer, we take safety extremely seriously and strive to make the safest LiFePO4 batteries possible. It is no secret that Lithium can be dangerous and whilst LiFePo4 is without doubt, the safest option, it is still not without risk. And that’s why we go above and beyond on both compulsory and voluntary extensive safety tests and processes. We choose to test every single battery before it leaves the factory by cycling to 100% and 0% and applying a high charge and discharge load to identify potentially faulty cells and connections, test BMS performance and verify cell balance at the top and bottom of the voltage-charge cycle. Our SMART3 batteries use only traceable branded cells from reputable manufacturers with lab test reports to verify battery safety as part of the EN 61619 certification. Finally, our product and fulfilment services also meet the courier requirements to ship Dangerous Goods under the UN3480 certification.
