Hi please validate my Wiring Diagram with Rotary SW-26 20 AMP switch it's basicaly a light switch continuity when set to 1 Pole 1-2 let current flow when set to 2 pole 3-4 let current flow.

Both Battery are 48V different amph I want more range from the factory Battery decide to add a battery from My other RadRover to help out.

The idea is to put both battery on the rotary switch POSITIVE wire one BAT1 to Terminal rotray 1 and the other BAT2 to Terminal rotary 2.

The Negative is put together on a Common BUS pole.

I plan to use XT60 connection 20 AMP to splice existing cable power Harness
