Description
The bar has been raised yet again. Roamer were the original designers of the Seatbase battery design and while many have copied the format since then, the 4th generation Roamer 230SEATBASE4 is the best iteration yet. Grade A+ matched cells provide 230Ah of usable capacity while a high power Battery Management System (BMS) with Active Balancing allows up to 3600W of continuous power - all in a custom case that fits neatly under a campervan swivel seat.

A front row seat to uninterrupted adventure
The 230SEATBASE4 is the newest version of the original low-profile LiFePO4 battery - designed for installation under a campervan swivel seat and tested with thousands of installations in almost every campervan model on the market including the VW T5/T6/T6.1, VW Crafter and Fiat/Vauxhall/Renault along with many coach built motorhomes.
We’ve used the same A+ grade matched cells and high-power BMS as our flagship 460SMART4, allowing us to fit massive amounts of capacity into a case that is actually smaller than the previous seatbase model. With a continuous charge/discharge rate of 300A, you can power any domestic appliance up to 3000W via an inverter. The upgraded BMS actively balances all internal cells, and also supports installation of multiple 230SEATBASE4 batteries in series or parallel - with auto balancing for parallel connected batteries. It provides a complete range of protections including low temperature charging.
