18650 magnet battery holder
thingiverse
A simple triple battery magnet holder for 18650 battery to make a temporary pack. You can make a 3S or 3P battery pack depending how you wire it. You can use wire or nickel strips for wiring. There is a triangle shape and an in line shape. It works better (stronger magnetic effect) on unprotected batteries because magnet is applied directly to the metal instead of the protection pcb. *WARNING : LiIon batteries are dangerous items so handle them with care and don't short them especially if non protected (check wiring twice). If you connect LiIon in parallel they MUST have the same voltage.* Bill Of Materials (Links below are affiliate links : it doesn't cost you anything but gives me few cents if you buy something) * 10x3mm Magnet [affiliate link](https://www.banggood.com/custlink/vKD37WrCja) * M3 Locknut [affiliate link](https://www.banggood.com/custlink/v3D3uCJrNG) * M3 Nuts [affiliate link](https://www.banggood.com/custlink/vvv31WCcAR) * M3 Bolt [affiliate link](https://www.banggood.com/custlink/vGm3TCCrO2) Beware, magnets are quite fragile; handle them with care.
