Slightly off topic, kind of, but: does anyone happen to know anywhere that does things like repair batteries of the type used by electric bicycles (Li-ion)? I bought a second-hand Giant EA 401 last year and while it’s been fine for its primary purpose of transporting my dog here and there or occasional runs to Costco, the connection inside the battery is loose and it sometimes takes quite a bit of fiddling before it properly connects with the charger. I enquired in a local shop about the replacement cost and then told me 10,000NT.
I figured there might be some business somewhere here that’s able to do what’s probably only a minor repair on the internals of a battery unit. Anyone?
