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

    RTV silicone of some sort. If they don’t have you return the old battery, then you can scrape it. Get an edge up, then use a qtip dipped in isopropyl alcohol in there to loosen the bond. From there work it with a credit card or plastic scraper and the alcohol qtip.
