I just swapped in 36s Chevy Volt batteries to a VX1. I am not yet using a BMS. The original nimh temperatures sensors were non-functional before the swap due to corrosion, so those temperature sensors have been removed. I am super excited that the scooter runs well; however:
- the original ESD charger only works for ~10-15 seconds then shuts off, likely due to the missing temperature sensors
- the wrench and temperature dash lights always flash, likely due to the missing temperature sensors
I would like to take a minimalist approach to get the ESD charger working and turn off the dash warning lights. I have the PCAN adapter, have successfully monitored the CAN bus, but have not attempted reprogramming any controllers yet. I have spent ~20-30 hours reading many forum posts to try doing this myself. Much of this information is from 8-10 years ago and there are frequent horror stories of bricking scooters due to something happening during controller reprogramming, which has me scared.
What are people's opinions on the Dugas versus The Laird's firmware files? Can someone point me to the most recent version and procedure to reprogram my ESD charger to work with these 36s lithium batteries?
