Battery packs and electronics are easy enough, I was more concerned about motors, which I believe is what Maddox was talking about.

Regarding the Ragebridge 2, it deals with spikes of current by limiting the amount of power going to your motors, therefore limiting the current that can be produced. Whereas other ESCs need higher maximum discharge rates to deal with the current spikes, the Ragebridge will ensure that the current never goes that high in the first place. I've read that the only real downside to this is it can slow down acceleration in some circumstances, but there were a lot of machines in Battlebots season 2 using them, so they're definitely suitable.
