where to buy battery cells?

Anyone have suggestions on the best place to go online to buy battery cells? Planning on building a battery…

If you’re new at this, you’re way better off hiring one of these guys to build one for you. Where are you located?


i’m in slc ut. new at it but think I can handle building one? It would be a hobby and a slow process. I’ve watched many videos and read a lot about it. already have all the tools. The circuit boards like what duck battery have are interesting but I’m looking to get a flexible style battery enclosure? I know it’s a bit of a mountain to climb but I’m thinking i’ll be up to it. I ultimately may back down and get one made? I’m wanting range, speed and flex? Any suggestions? thanks for any help and being “straight up” with answers!

Battery building for esk8 can be much more complicated than a lot of what you see on YouTube, especially since we have factors like flex and road vibrations that we have to accommodate for. There are lots of really good resources here for battery building, and by reading The battery builders club thread. You can learn a lot. There are lots of pictures, problems and solutions that you can learn a lot from.

Any questions you may have during the process are better off placed there as that’s where you’ll have experienced battery builders looking.

The biggest barrier to entry for esk8 battery building is most likely going to be upfront materials and tools cost as stuff like 0.2mm nickel strip, spools of good quality wire, the spot welder, and everything else you’ll need will cost you quite a bit. You can start by having a battery builders weld you some P groups so you’ll be responsible for series connections, BMS hookup, and any other wiring.

There’s only so much I can fit into one post. But give the battery builders club a good read. Its like 20000 messages, but scroll through it and take a close look at some of the pictures and mistakes others have made. They’re a great tool for learning.


thanks, I will and have a bit so far but yeah there are extensive threads. The flexible battery for a flexible enclosure and board to go along with it, is taking some reserch…

Have an idea for what deck and enclosure already? Many people here can show you pictures of what their existing batteries for a certain setup looked like


Add your location to your profile

edit: please

It will help you help yourself




Which welder do you have? Do you have nickel shears or a corner chomper? Do you have empty practice cells? Do you have a multimeter? Which lipos are you using for your welder? What are you using to charge them? Have you sourced nickel? Have you tested it for purity?

There are a LOT of things you need and it’s not really feasible to learn to do all this and invest in all the tools just to build one copy.

Buying a battery from a reputable builder is a really good idea.

Also keep in mind order of operations


They’re the ones asking for help. Adding their location to their profile helps them get help.

I am a polite person but this is just to help them mostly.

“hey, go pick up that lost money in the roadway”


“hey, go pick up that lost money in the roadway PLEASE”

I think he had a point that you came across as a bit stern. Please probably doesn’t make sense in that context either, but “adding a location to your profile can make it easier for us to help” is probably better. The original gave me grumpy old man vibes.

Cheers, updated and noted for future

yeah deck and enclosure is where I’m at in research, so far the Volokno FLD is looking like a good option. Thanks for the list, I sure get hit up by battery builders saying no way on my own and wanting to sell me one??? We’ll see, I would definitely buy all battery parts from a reputable place, if I get scammed on inferior products guess it’s lesson learned. I’ll way the battery make or buy scenario along the way.

Getting fake or grade B or just low quality cells is most assuredly a proper concern, but procedural problems based on greenness seem more likely to cause bigger problems IMHO.

Ooo the volokno enclosures are nice and spacious, pretty good for a first time flex pack. I’m curious to see how this goes, Im low-key interested in getting one when I get the moni.

Heres a few places you can get genuine batteries in the US.


Once you find which cells you want, your next concern should be sourcing real pure nickel as it’s been pretty hard to get that stuff lately. We had a go-to AliExpress store but they shut down unfortunately.

I’m getting everything from alibaba, think I got a line on a perfect cell for a 1$, perfect!!

This stuff can be highly dependant on what deck and enclosure you really end up with. Brian posted a good order of operations you should follow with esk8, so I’d start by making a decision on which deck and enclosure you’ll go for.
