Has anyone here tried using power tool/mower batteries to power a go kart? I'm talking about the 80V 5AH packs from Greenworks/Kobalt. I've seen some builds on YouTube using them but nobody here seems to mention them (or at least no posts I've seen). I feel like it makes sense.
The buggy I'm currently building has a modified 440cc 4 stroke industrial engine that puts out around 21 horsepower peak. I plan on (eventually) converting it to electric. I do not have the equipment nor the know-how to build my own custom battery. So I figured that instead of using a gas lawnmower engine, I could use a lawnmower battery. Most of the ride-on electric mowers use 6 of these 80V batteries. And at 80V (72V nominal), 40A max draw a piece, get 6 of them in parallel and that's theoretically over 17KW and 30AH. I would probably run them closer to 15KW (35A a piece) since I don't want to blow the internal fuses in the packs which (according to what I've seen online) are 40A fuses. lt also allows for the option to swap out the packs quickly assuming you had an extra 6.
Do you think this is a good idea, or should I just wait for pre-made packs to become more common?
