Build quality okay but not performance.Arvosana 2/5
I have a GZR pedelec longhaul and I’ve been testing this battery for the past 1 year. The battery starts blinking after roughly 10km feom the beginning and now after 10-11 months it barely makes it to 4-5 kilometers. This is my second battery and also 2nd bike. So I’m sure that the issue isn’t from the bike. Also I weight around 70kg and riding it mostly on a flat city suburbs.
