Vinteky 20.8Ah E-Bike Battery for Panasonic 26V (Raleigh, Kalkhoff, flyer, Kettler& Rixe)

I received mine today and and it fits and locks properly onto my gents 2009 Kalkhoff Pro Connect. (Thanks for answering my question Robert Ryan.)As other reviewers have said. its a lot wider than the older 10Ah battery it's replacing.I'll try it out in a few days and hopefully come back here to up-rate it to 5 stars.EDIT:I've been using it for a few weeks now during Covid-19 lockdown. The capacity of the battery is amazing. I've done journeys of over 25 miles, including stiff climbing, and have never got the charge indicator below 4 lights. (I used to be cautious with my elderly 10 Ah batteries and always ensured they were fully charged before a trip.)

The battery was well packaged when it arrived, physically bigger than the original but still fitted into the battery bay of my Kalkoff e-bicycle. I've only had the battery for a few weeks but so far it looks very promising ..

As we can no longer get replacement batteries from Panasonic, these batteries offer a life extension to ageing but still capable ebikes. Good range and so far very reliable.

This fitted perfectly and locked into the existing locking mechanism on the Kalkoff ebike which is about 10 years old. Shame they don’t seem to be available any longer as we have another bike that will soon need another replacement and I appear to have one of the last ones. Is this due to Brexit? I live in Dublin, Ireland.

This battery is twice the size of my original one, but it still fits...and it lasts longer.

Very happy with the battery, everything seems to be working fine. It is to early to give a proper review, but for the money, I'm hoping it will at least half as good as the panisonic.
