my ebike battery isnt charging, any tips to remove the white goo on the leads of these wires?
Hey there, I got an e-bike a while back, and suddenly the battery stopped charging. I thought it was the charger, waited for a replacement charger and then that didn’t fix it. I have a bit of background with electronics so I took the cap off the battery and poked around with a multimeter. I think the issue is the connections of the charging cable, anyone know what this white goo on top of the wires is and how I could remove it?
The battery was under warranty so I’m getting a replacement but I’d hate to throw a mostly good battery in the trash
There is all sorts of intelligence in that thing that regulates when and how much it is charging/discharging.
I doubt the main power connection is broken but it probably is switched of unless it is connected to the bike to prevent damage to the bike and you and your house.
There is also probably temperature sensing in it, which could be broken and prevent the battery from functioning because the controller thinks its overheating/freezing.
Edit: Also with stuff that you expect to be outside in the rain (like a bike) you really dont want to have a bad seal on the battery. If you get water or even just humidity in there it will lead to all sorts of bad stuff chemically and electrically.
