3S 12v 18650 battery
Description
Uses 10mm wide nickel-plated strip for contacts. Print two of em - top and bottom. Zipties to hold the entire thing together. 3mm wide ones work fine. If anyone could space the cells equally it'd be great as I'm too green with sketchup to do it myself. //Edit: Fixed the holes up a bit, my cells were little bit too tight due to the isolation. Sorry!
