Shutting power off on a tank?

I take it you don't have the battery backup for your VorTechs? You can still run them at full power if you can get two 12 volt DC batteries hooked up in series for 24 volts DC. You'll need the connector that provides power to the driver same as the plug in power supply. Make sure you get the polarity right though, I think + is the center pin. If you only have one 12 volt battery, you can run them in backup mode (half speed), but you'll need the smaller connector for the driver's battery backup connection. Could be a bit of a challenge getting all the parts together for that on short notice though. In addition to the connector(s) and wiring you'll need a couple of deep cycle batteries and some clips to attach the wiring. Car batteries will work also, but not ideal since they're designed for cranking power, not extended slow discharge. Should be fine for a day though.
