Hello everyone! I’m new hear and was hoping to get abit of help. My son has a Ford ranger 12 volt electric car with 2 motors. The battery on it kept dying so I swapped it for a 26 amp/hour 12 volt battery and also swapped the 2 motors for a identical but higher rpm ones (12000 sapped to 30000). After putting it all together, ising the controller I sent it up a hill. After a couple of seconds it cut out and the circuit board was smoking so I stopped and turned it off. I then checked all the wiring and tried it again with the same result.
Any ideas what I’m doinng wrong??
Thank you in advance!
