They don’t last!!
Purchased a YOSE POWER E-bike Battery 24V 10.4AH it failed 6 months after the 18 month warranty. It was very lightly used but maintained as per instructions. The ‘UK’ based customer service has provided no assistance, warranty has meaning under consumer law, it should last a reasonable amount of time which it has not!! I even purchased a replacement charger first to see if that was the issue and I have had no luck returning that as it obviously wasn’t, so I ended up more out of pocket!!
