I am posting this query on behalf of a friend , He bought an Easylife 24 volt lithium bike for his daughter who uses it for daily commuting . She has owned it about 18 months . The charger failed under guarantee and was replaced . Now here is the problem . The newly charged battery is installed in the bike and the red amber and green lights come on as normal . The battery shows 28 volts when tested with a multimeter . After about 100 meters , even on very low throttle , the bike cuts out and all the lights go out .You can get a repeat performance by switching the key off , switching it back on , and trying again . As a temporary measure the bike is being run on a 24 lead acid , and works fine . So the problem looks like the battery . Can anything be done to this battery , or is it scrap ?
