Roamer leads the pack with their product, and when you couple that with their customer service, it amazes me that people buy elsewhere. Honestly, forget Renogy, Fogstar or anyone else (I've used them both before, but never again). If you value domestic experts with can-do, positive attitudes who genuinely want to help you, then look no further, you've found the holy grail of van electrical companies.
Nice when you come across a company who really cares about what they're doing! I've been in touch with them for various bits of advice regarding choice and installation of my Roamer battery, and without fail, everyone has been really friendly and helpful, willing to spend the time regardless of how seemingly trivial the question is.
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!
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. Roamer are a battery specialist and not a Solar company however I do not think my 4kw off grid system would up and running now if I had not had all the help from the various members of the Roamer team. 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.
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 are always there, exactly what you need from this type of purchase.
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!
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.
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. Big Fan
I was impressed by the degree of interaction offered by the sales team, always keeping me appraised of the order status. They swiftly and effectively answered the technical questions I posed them and offered me links to further information resources. This was all done in the most friendly and unstuffy manner. I would highly recommend dealing with this company, a most refreshing experience.
Steve at Roamer batteries has been very helpful. Being new to 12 volt systems it has been a steep learning curve for myself and Steve has been great at answering my questions when they have arisen before, during and after the install. Thanks again :-)
Fantastic service from start to finish and the post sale backup is second to none. The products are backed by a ten year warranty so if you're thinking of going lithium, go Roamer!
Great company. Excellent value and unbeatable customer service. We finally feel comfortable enough to finish our conversion electrics now!
