Update 10/01/2020 The new box is holding up great, I’ve ran 3 Pack sets through the Ride On back to back on a trip to a park and back and the box did not show any signs or overheating or potential failure. This new box appears to be a great purchase so far.
This video covers a replacement electronics box to purchase when upgrading to Lithium batteries and larger motors. This will also cover wiring the new box which is slightly different but very easy and only requires a few easy to find wire splice connectors
Old Electronics boxes blew up again, purchased a 24v (NO I am NOT running 24 volts) Electronics unit that was a near drop in replacement, I detail how to hook it up at the end of the video. So far its holding up great and I don’t think I will need to modify it to add cooling.
The unit is under $30 and works with the stock remote…. except the steering is reversed. However you can get it with a remote for something like $10 more.
