- Venturing out into the wilderness requires total confidence in your gear. And that’s why it’s our mission to make off-grid batteries with unrivalled build quality. We start with the highest quality Grade A+ cells and a custom high power BMS, then add precision-engineered brackets, flexible copper busbars, and serviceable IP65 cases. Open up a Roamer battery and you'll immediately notice the difference in quality compared to our competitors. Backed by rigorous testing processes and our 10 year warranty - consider our mission accomplished.

It is refreshing to see a product in the motoring world that has an impressive look of its build quality. There are many companies around these days insisting that the products they sell are top quality, but when you see the insides of these the true story of the product come to light.
Well done Roamer!!! its unusal for me not to criticize a product.
Thank you is much, that means a lot.
Excellent video with some really convincing reasons for paying more for the roamer battery than cheap alternatives!
I suspect that you can't edit that at all, so I thought I would point out that the bit of yellow/green tape visible at (for example) 6:50 is there because you have disconnected the negative bus from the cell terminal is NOT part of the normal battery construction...
I will be ordering a 460SMART3 today I think (it takes me some time to pull the pin on a big expenditure)
Great to see the actual product opened and explained really well . Thanks for the video Steve .
Great to see a strip down of the product.
Just wondering how the flexible connection are better that using the correct size cable and joints
Love the steel box to clamp together.
There’s a few reasons for the copper busbar… one, it’s solid copper rather than the standard aluminium braid cable so less resistance and lower losses. It’s correctly rated for the max load by the way, calculated using UK regs. The flat surface also creates a better connection with the BMS and battery terminals… again less resistance, less voltage drop and reduced chance of a hot spot. You do NOT want that on your cell terminals! Finally, it’s a solid piece of copper from one end to the other (as opposed to than a ring terminal crimped to a cable, then crimped again to another terminal at the other end). Less connections, lower resistance and fewer points of failure. Of course the downside is it costs substantially more than cable but it’s carrying a serious amount of current so it’s worth it 👍
@@roamerbatteriesthis is good to see I've always been slightly worried what was going on inside when I draw high currents
Really interesting video Steve - when I originally discovered Roamer it was the quality and the 250A BMS which drove my decision (oh and it fit in the space I has available perfectly).
I believe I have the original (First series 460Ah) which had an amazing spec for the time and is serving me well to date, the magic you want with tech where it all just works for me.
What’s the difference between the first, S2 and the S3? I’ve seen slightly different behaviour at times compared to mine when helping people so was interested.
All the best, David 👍
@@LeisureBitHi David, lots of little upgrades on the SMART3. The build quality shown in the video is what you get now… cell brackets, busbars etc are all new for SMART3. Cells are now traceable which gives consistency and confidence in quality. We updated firmware and short circuit protection to fix a couple of niggly BMS issues so that now works perfectly. We also added an independent Active Balancer which has eliminated problems with cell balance caused by using the battery incorrectly. Makes it much more forgiving of poor charge profiles - campervans will often have lead acid only chargers fitted and will be in storage for long periods. Active Balancing sorts this out, we never get issues now. Will also extend useful life by ensuring you always get max capacity from the cells. So its incremental improvements but added together mean batteries are very consistent and reliable. Returns have dropped to almost zero, everything now just works and we expect batteries to have a much longer useful life👌
@@carmadme I’ve seen a few hotspots at high amps due to cheap cables and poor terminal connections… you do NOT want that happening inside a lithium battery.
