I have a Razor Ground Force Drift with a burnt control module and dying battery. Thinking if I'm going to fix this might as well make an upgrade. I'm a big fan of Ryobi +1 products and have a some 40v 94wh li-ion batteries that I use with my yard equipment. I would love to figure out how to make them work where I can use the regular Ryobi charger and grab the batteries with me when we go karting with the kids on the razor. So a plug in solution is what I'm looking for kind of like a cordless drill..power runs out replace with another battery while the other one is charging. I have some ideas on how to do this and need help with the rest of the hardware on the cart.
1, What will I need to upgrade Controller, Motor etc
2. Cheapest scenario..what can I keep stock but use the 40v 94wh battery
