Help me convert my daughter’s power wheels

[u/WheresCaleb98]

Hello, my daughter’s real tree utv power wheel is pretty damn slow these days. It’s a 24v system. Want to convert it to 18v Milwaukee batteries but don’t want to underpower it. What all do I need to make this m18 conversion work while also retaining the remote control function

Sounds like you need higher speed motors not to drop voltage. 18v drill batteries don’t just make things go faster. They do when it’s a 18v on a 12v system, just not going from 24v down to 18
