Batteries, batteries and more batteries. Plus some wiring…

Yep, you got it. All I have been doing is playing with batteries!

After a few hours of looking at how to make them fit, I finally came up with a way to get all of them within the engine bay. So I welded the lower frame together and started on building a metal box around the batteries.

Now to meet EU guidelines (boring!). Any battery box must be sealed and require tools to gain access to any high voltage connections. A big metal box should solve that. So it’s time to build a removable lid to finish it all off.

Next up, wiring. Luckily I had help in the form of Tippers. Everyone needs a Tippers. He has spent hours stripping out the old wiring loom and removing everything that’s not needed. Now he has to put it back in.

I on the other hand have to look at wiring up the BMS (battery management system). Lots of wires – 96 to be exact. Each set of cells has to be monitored, so loads to wire up. But it’s vital, as the BMS makes sure everything stays safe and keeps all the cells balanced when I’m sliding around the track. I think I will leave this bit till later on in the build.

I have managed to get my hands on a Tesla rear subframe and next time we will be fitting the rear motor. It’s going to be wide!
