I'm really excited to be able to join a forum with people willing to convert a car to electric. I decided to ease my way into an EV conversion by buying a used Ford Ranger that was converted by a professional garage. I realized just how complex a conversion can be after buying the conversion and looking it over the past few weeks.
The issue with the truck is that it is running very slow, the max amp draw reads about 45A and the max allowable is 500A (without any discharge limits).
When I first bought the truck, one battery was at 3.26V and all the others were at 3.32V. When I plugged it in, it would charge for 30 seconds and then stop. I charged the low battery by itself with a power supply to bring it up to 3.32V because I thought it wasn't charging due to the low battery voltage. After that I bought the Orion Candapter and was able to communicate with the BMS. The batteries showed 94% state of charge and there were no errors reported. The Curtis controller is also not reporting any errors on the leds (flashes yellow). Is there a way to test the remaining life in the batteries?
