8 X 18650 Battery Case

thingiverse

I know there are hundreds of 18650 battery cases/holders available, but none exactly suited my needs. So, I decided to design another case for these batteries myself. This one can hold eight batteries and be wired in almost any way I want. I personally needed a 4s2p setup, so that's how I wired it. The wiring shown in the pictures isn't ideal, but it was just for testing purposes. I plan to use my flashing tool to add four screws and drill new holes that match. I've created two versions of this case so far. The V2 version is a bit thicker and heavier, making it suitable for applications that require extra durability. Unfortunately, I don't have any protective caps for this version yet, but I can make some if anyone is interested. The V3 version is smaller and uses less filament, but I think it's just as strong as the first one. It also comes with protective caps to cover all the screws and prevent short circuits. These caps are only available for the V3 version right now, and they come in four different types, each with a unique hole pattern that fits over the ends of the screws, nuts, or wires. Both versions have a body that can be used to enclose the cells completely, making it look like a finished product. However, I haven't printed either of these bodies yet because I don't currently need them.
