Hey that's cheating, I did mine with a jig saw.

Started the battery build. I used VHB tape between the cells and a couple of tie wraps to keep thinks tight together. I have it all assembled on a table for testing before I install in the camper.
Wiring for the BMS cell monitor, I have a 150A fuse on the positive terminal and there is a temp sensor also attached to the positive terminal.
Here you can see the 45A charger with a 50A circuit breaker, 2000W Renogy inverter, the shunt and power monitor. The BMS is on the left side of the battery. It is a 100A BMS from battery hookup, I will replace it with a Chargery when it arrives from China.
Battery monitor showing 41.5A charging, sorry for the out of focus picture.
Victron BMV-702 app display.
Battery Hookup BMS App display.
Once the battery finishes charging I will put a load on the inverter and see what capacity I get out of the pack.

The battery test finished and I got 186AH out of the battery. I think if I top balance the pack I should get the full 190AH that the cells were rated for. Next step it to buy/build a battery box to hold them. I am tempted to build one out of ABS to keep the size as small as possible but I have a 6V sized battery box that is not too much bigger than what I can build. I think I will try to use the battery box and only build if I need the absolute minimum space.
