Well done! I’m collecting a library of videos from you guys who are repairing these expensive batteries. Thank you. Winner winner chicken dinner is right!

just had one of mine do the no charge when put in the cradle. Took it apart and removed all the silicone off the board and looked through the magnifier and low and behold, there was a lifted resistor from the factory, soldered it back down and Wala

Great job! I’m fixing to have to tear my 5ah apart. Has a green light but won’t charge. Has 49v on it.

What caused the trace to burn out was improper assembly at the assembly line due to contaminates entering the prodiction line from chineese laborers in a village that that get paid .50 cents a day, no clean room no esd straps no bunny suits, srcond someone touches the mother board with bare hands its doomed to failure. Never mind poor QA.

👏👏👏👏

What did you use to take the white glue/ connector’s coverings off?

hey i have a 6.0 AH battery would you like to work on that?

2 reasons why i see so many ego batteries going bad and red circle of death after first two years and this is gen 4 im talking about, 1) they keep using cheap generic no name 18650 batteries in parallel, and secondly and most important they are designed with subpar discreet wiring of 24 guage or smaller. Ego, listen to me on 56 volt batteries? Really???? The wiring on military aircraft is bigger than that and its onjy 28vdc. Abf has to be light weight. Come on now ego, you can do bettet tgan that l, stop making disposable batteries. Make domething customets can be proud if and btag about in reviews.

Thousands of fires each year from idiots tampering with defective batteries and yeah......great idea to make a video of this and post it on here. No schematics, no idea what all those components are, just tell someone to do this and take chance of burning their home down. Things fail on these boards for a reason.
