Mostly looking for any tips that anyone can give as I embark on this project. I still plan to read a lot more threads and guides and do alot more research before I start but I wanted nail down some specifics of the plan before hand.
So I’m slowly doing some research to make a replacement battery for my Backfire G2s in order to replace one that’s getting old, as well as solve a few issues I’ve had with the old one.
Namely I want to make a battery that:
-Can work in colder temperatures
-Be brought on a plane
-Have a longer lifespan so that I don’t have to replace it as often.
For these reasons I’m planning to use LiFePo4 battery cells making 2 packs that are under 160wh’s (under airplane restriction limits) that I can then hook up in series when riding and take a part to bring on a plane. I expect the packs will end up being 12s to get up to a voltage of 36v (depending on the cell obviously).
Mostly looking for any tips for:
-Cells to use.
-BMS to use and should I have one main BMS or one for each pack set up some how in Parallel.
A123 26650 cells are pretty great. I got a ton of them from battery hookup I’m planning on making esk8 packs with them, if I had my spot welder running I would offer to make one for you.
