One of my bikes is a conversion - the front hub nano motor with 6ah li-on battery. I've had it over a year but used it sparingly - mybe 200miles at most. (Iprefer my wife's kalkhoff agattu).
The battery recently only gives me 5miles or so, and it takes only 1 to1-1/2 hrs to charge fully compared to 4-5hrs when it was normal.
The 3 LEDs stay on right until the end when they all go out - they used to phase out as the power was depleted.
I've checked the battery voltage when charged - it is 41-42V, and when empty is 7-8v.
I've put the bike on a stand and run the battery down from full 3 times but made no difference.
Any ideas anyone.(Yes I know.... stick to the kalkhoff....) It seems a lot of money for a battery which doesn't last the pace and I'm very disappointed.
