First battery stack

I've just assembled the full stack of battery modules on a quick visit to the shop. Here's the result:

The assembly went well and most measurements seemed okay. I felt the compression I made on the rods was not 100% equal but it's hard to measure.

Next step is to fabricate some bus bars and insulators. I still have to figure out how to "fix" the uneven positive/negative module (I have 7 and 5 of each, instead of 6 symmetrical ones) without over-complicating stuff...
