Enhanced 12s2p / 6s2p battery holder for spot welding (18650 Lithium Ionen cells)
thingiverse
This is an improved version of my battery holder for a 6s2p or 12s2p battery pack of 18650 Lithium Ionen cells. The battery holder is made for DIY spot welding battery packs with 7mm Nickel strip. The battery holder was optimized to fit in the battery enclosure of a DIY Funwheel together with a BMS laying on top of single row of battery cells. It's now optimized to use as little space as possible. The new version also has better auxiliary cutouts for the balancing wires of the BMS. For a 12sp2 you'll need to print all 4 parts, spot welder the two 6s2p packs together and fold them. For a 6s2p only 2 parts are needed.
