I'm in the process of building a 36-mace hs. The final thing that I had to do was stack the batteries but I tried and failed. So, I took the battery out because sometimes when I put it back in, I can stack it easier. Now the battery won't fit in and it's really annoying me. The worst thing is, I tried to BFE it in and my bot has no power. The battery won't work.
P.S - I'll post pictures up soon, if it will help.
