Glad I found this post we had chewed through some regular AA batteries Christmas. I did a rather simple mod using an existing lipo I use for my RC car it worked great. I used some crocodile leads to make the connections which is a bit crude and a little worried about shorting it if they come loose but work in progress and they seem secure. The battery mount needs some work but the lipo is light enough and mounted centrally which works. Now looking for a smaller battery ONe that fitted in the rear would be good. I have a friend looking to 3d print me the case. But mean time endless hours of fun with the new 4x4. Thanks, Philo for your work
