Nicely done!

Thanks for watching!

[@unprofessionallytrained3956]

do you know if those black and decker batteries have under-volt protection? if not you need to pay close attention to the performance of the thing you plug it into so the battery doesn't get ruined

[@wackyengineering]

We have the kids trained to park it as soon as the battery starts to wear down a little. We haven't had any issues yet!

[@m4l520]

Did you have to change the motor or gear box? I swapped my kids' power wheels with a 40v battery and adapter, but I think I burned something out. Any recommendations? Thanks

[@wackyengineering]

Yes! Check out our video on upgrading the motors and gearboxes with some 24v ones. Links to parts in the description of that video.
