As long as the power ratings are within 400amps (10c) for 30 seconds and 120amps (3c) continuous they will be suitable for any vehicle.

The main reason we are targeting golf courses to begin with is the frequency to which they are being used.

These cells are operating at 90% DOD.

Remember the voltage sag is significantly reduced with these cells in comparison to lead acid, which means the higher amperage of the controller is not necessary. The 48v pack itself is running at 51.2 volts.

True and true, got cha. No huge controllers... The reduced voltage sag is very significant. Building a lipo rxv today and tomorrow. Who's charger are you using?
