Thrifty Tool Shed's video: EGO 4 0AH Battery Repair 2 BMS Wiring

In this video we take a look at 2 EGO 4AH packs needing repair. We find one battery in terrible cell condition, but one has a suprising issue with the BMS wiring. We are able to use the BMS wiring from one pack to get the other pack going strong. I also found later that what I thought was the spare BMS board actually had issues as well. Stay tuned for the next video looking into the BMS Board troubleshooting on it! Hope you find it helpful and Thanks for Watching! Northridge Fix Affiliate Links.
