schematic of my bicycle battery

here’s a video showing how i made half of my new battery. the battery pack i built is 24v 35ah and i will built a second one to run with it. its just building two would be boring in this video and delay it even longer.

if your looking for laptop battery packs to go to ebay and search “laptop batteries” then go for “buy it now” so you can buy like 15 packs at a time. organize the search for lowest price/shipping. and ebay even has an option to limit the search to how many cell are in the packs. and you should be able to find packs that are about 1$ – 1.5$ per cell.

thanks for watching, this was a very rewarding project.especially going 30 MPH up those hills. i feel sorry for my battery on that test though haha. i’ll be doing a distance test video soon, and then another when i get my 2nd battery block done. the battery should already be big enough for me to drive between towns instead of just in town.
