This is the eZee flat pack battery used over the years in eZee conversion kits and some complete e-bike models such as the eZee Viento, eZee Vente and more recently in the eZee Radkutsche Rapid cargo bike.
Although there have been different energy capacity versions available over the years (anything from 10Ah upwards), they have always been the same physical size. So you can replace your old one, whatever it was, with this one.
The 20Ah - 700Wh, is the only version currently available.
