Hello. Absolutely great job! Did you really say 600 amps? At that voltage, 600A would be about 100KW or 134 HP. Is that correct? That seems quite a bit of power under the hood. Your wiring must be substantial to handle that amount of amperage. Any reason for chossing 6V batteries over, say 12V?
Yes, 600 motor amps, but the amps coming from the batteries is substantially less at a maximum of 225 amps, (Hairball controlled). All of the battery and motor wiring is 2/0 welding cable. The batteries sag to 156 volts, so 600 amps would be about 90KW or 96 HP. For a short burst then the amps drop off to about 350 amps or 55KW @ 73HP. Two, 6 volt batteries have more plates than one, 12 volt battery and therefor the two, 6 volt batteries will give more power than a single 12 volt battery.
Thanks, that makes sense. Except for maybe one point in that if you're measuring motor amps when you're doing your HP calculation you should also use motor volts. If your pack sags to 156V @ 225A, you're probably running ~47HP. Still, that's quite a bit of power.

Great work! What are the other meters showing?
