Just picked up a Lil F150 yesterday. Nothing wrong except a worn out original battery. I cut the box out and stuck a 12V 18ah in and it ran like fire for about an hour until it started slipping. I've looked through the forums on 3B Gearboxes and I haven't been able to find a definitive answer on if it's possible to run these on 12v? Can I put 775 motors on a new factory 3B or will they still tear the gearbox up at 12v?
