A front row seat to uninterrupted adventure

The 230SEATBASE3 is the newest version of our original low-profile LiFePO4 battery - designed for installation under a campervan swivel seat. We’ve used the same A+ grade matched cells and high-power BMS as our flagship 460 SMART3, allowing us to fit massive amounts of capacity into a case that is actually smaller than the previous model. With a continuous charge/discharge rate of 250A, you can power any domestic appliance up to 3200W via an inverter.

The upgraded BMS actively balances all internal cells, and also supports installation of multiple 230SEATBASE3 batteries in series or parallel - with auto balancing for parallel connected batteries. It provides a complete range of protections including low temperature charging.

Built by adventurers with a genuine passion for van life

The Roamer 230SEATBASE3 uses the very best Grade A+ matched cells and comes assembled with precision-engineered brackets, laser-welded cell connections, flexible copper busbars and an IP65 waterproof case.

Maintaining excellent balance throughout its 15 year life expectancy, your Roamer will deliver stable, high power with every cycle. Our additional factory and warehouse testing processes ensure the highest possible quality and because we believe in our product, we back everything with a 10 year warranty.

To ensure maximum lifespan, every 230SEATBASE3 comes with a state-of-the-art internal Battery Management System (BMS) with Active Balancing - developed specifically for Roamer to support high power off-grid living.

“Fantastic service from start to finish and the post sale backup is second to none.”

Rob Landsman

My partner and I have had the pleasure of buying a battery from Roamer. Being new to the campervanning world we sometimes need all the help we can get, and the people at Roamer offer help and advice by the bucket load. Today we received help from the amazing Steve and then had a follow up call from Chris, two of the nicest people you could ever wish to speak to. We can't recommend Roamer highly enough. Their products are very well made and after sales service is second to none.

Rebecca Freear

Having had an A1 buying experience with the guys at Roamer batteries, we were confident to ask for help when needed. Steve spent ages on the phone, patiently going through settings on the charge controller and advising re apps and appliance energy usage. Chris called twice later to make sure we had got the information we needed. If only all companies were as caring and thorough as Roamer Batteries, they are a top class small British business!

Joseph Parker

First and foremost Roamer batteries “do what they say on the tin”. Having purchased batteries before that did not live up to their amp hour claims, this is a brand you can trust. Setting up an off grid system at home to avoid energy price increases was made a good deal easier by all the help and advice. You can always buy cheaper but I am not sure you will ever get better value for money when it comes to buying top quality batteries.

Graeme Kerr

The team at Roamer are fantastic. Seriously, if you are in the market for this type of product I wouldn't recommend another company. After placing our order, Steve and Chris have been nothing short of brilliant in supporting us on delivery updates, schematic design & support, video calls, install advice... the lot. We are relative novices in this area and ask a lot of questions but the team is always there, exactly what you need from this type of purchase.

Indra Åkerblom

We are extremely pleased with the help we got from Steve and the crew at roamer batteries. We needed to upgrade our battery bank and they helped us out. Such a good price for what you get, extraordinary customer service and they really went above and beyond with helping us sort shipping and installing the battery. Would highly recommend it!

Rowan Robinson

Been thinking about going lithium in the van and came across these guys who have some pretty sick branding. Spoke to Chris who answered all my questions and said they could design me a full system to suit my needs along with a battery! The fact that they took their time talking things through with me was the clincher, the customer service was great! Friendly and knowledgeable, I can definitely recommend these guys.

Felix Van Spall

Roamer supplied the electrical design for our self build camper which saved us weeks of research and newbie mistakes, I highly recommend to anyone taking on a self build. Roamer also supplied all the electrical equipment (price matched) with telephone support fo the install - great when you have those little recommendations and questions you're not sure about.
