Martin, That is some impressive circuity. I noticed a PCB with relays, capacitors, IC and resistors. Was this a PWM board? Did you make this part? At 2 lb. That is some very effective wiring. An electric car motor, will typically max at 500 Amp @ 144 volts. The Curtis controller does this for about $1500. Dragsters run up to 2000A using a Zilla controller. (No relation to Bob Zilla).
