BCP 4pcs Plastic Li-ion DIY Battery Case Holder for 4x3.7V 18650 Batteries

lately I've been seeing a lot of solderless 18 650 holders showing up on YouTube and online but honestly I thought so far they're all very expensive and don't like the design of a lot of them a lot of them use these like a tight pressure fit on the cylinder and that looks like it could come loose over time and I haven't been impressed with them and I had the thought I'm pretty sure I could build my own solderless 18 6 650 battery box just using cheap eBay parts and I've been working on it and I think I've come up with a quite a good design this is my first prototype here and you can see it is it is a very strong solderless battery box right here these are 8 cells in parallel so this is only 3.7 volts but you know it could push over 100 amps if it needed to the way I have this designed is I am using good old spring clips from a like a like you would get in like a double-a or a triple-a t
