After a while without working due to battery problems, I decided to open it and replace the battery on my own, since I couldn't find the original battery to buy I improvised with what I could find in Brazil

I bought a 12v battery from Makita screwdriver, opened it and redid the circuit to be compatible with Lightning McQueen's, it worked super well and the autonomy improved a lot compared to the old battery at the time when it was new, with this new battery I have autonomy of almost two hours playing with McQueen
