What about getting a LM2596 DC-DC Buck Converter 4-40V to 1.25-37V Step-down Regulator and taking the Voltage down from 40v to 24v. I think the amperage is maxed out at 2-3A will that be enough for the cart. I was unable to find the amp draw for razor products although he controller says 24v 30amps?
The controller is rated to demand a maximum current of 30 Amps from the battery pack and the Ground Force Drifter uses a 30 Amps fuse so a DC-DC converter with a maximum output of 30 Amps or higher would work best with it.
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
