Battery rebuild?

Postby nez dans le guidon » 13 Oct 2018, 9:59pm

Anyone rebuilt a battery or had it done? My wife has a lovely Koga e-runner which I’m borrowing since I was flattened out by a pulmonary embolism (maybe I need a rebuild). She only rides short trips so hasn’t noticed but I reckon it’ll only do 25 miles before it goes flat so I’d like to get a new battery (500 sovs!) or maybe a rebuild (more economic). Any advice?

There have been various threads on Pedelecs. I think 'recell' is the key term. eg see

Jimmy seems to have been recommended several times, I think he is BGA reworking but I may be wrong.

JImmy is the battery guru.
He runs three tech companies form the same premises.

He can recell an old battery with better cells and more ah/wh for around 300 sovs.

He openly say's major bike component manufacturers are ripping folks off for batteries esp likes of Bosch who want £700 for a new battery.

I had it done by Jimmy. Excellent, pain free process. He managed to update the battery from 10 to 15 Wh
