I bought a kit from these guys https://www.aliexpress.com/item/12-Parts-Whole-Set-E-Bike-Refit-Kit-With36V-500W-Battery-LED-Display-Controller-Motor-Brake/32524917815.html?spm=a2g0s.9042311.0.0.774a4c4dEmsx8L.
Has been working fine until now. The bike has done 1000 miles and probably about 60 charge cycles. The battery charges fully, show 42V on full charge. However when riding now voltages fluctuates widely, power cuts out regulatory and sometimes the bike computer just shuts down. With a bit of experimentation with the throttle voltage is steady until I get above 2 Amps but above that starts fluctuating. Thought maybe I had a loose connection in my wiring somewhere but with this behaviour I am thinking its the battery. Is this the kind of problem you would get if the battery was dodgy.
I have fairly limited electrical skills (I know how to use a multi-meter and could do some very cack handed soldering). Given that is it worth trying to fix.
If not any recommendations for batteries in the UK.
Thanks,
David.
