Hi All,

I put a Bafang 250w 36v BBS01 mid drive on a bike several years ago and the battery needs replacing (as it dies under load, needs charging after 15 miles etc)

The current battery (pun not intended!) is about 9MaH (Kettle style) so was wondering what there would be in terms of an upgrade, maybe double the capacity?

The connection from motor to battery is a 3 pin plug (looks like an XLR connection if anyone is familiar with audio leads!)

I use a 17.5 amp hour battery and can squeeze 90 miles out of it between charges. There a bit pricey but worth it in my opinion. Mine came with the kit from Woosh.

I bought a shark pack from Eclipse cycles, mounted on the downtube. How easy it is depends if you are confident with mounting it and altering the wiring.
