I bought a used Ecotric Hammer that I could not test drive at high speed as it had no brakes. After getting it repaired, it loses power occasionally especially at higher speeds. I can turn off the key on the battery off and back on again, then power up the bike and it restarts. Once it loses power, the test button on the battery does not light up, but it will after the restart. Before losing power, the battery gauge will move up and down from full to 3 bars mostly when speeding up. The longer I ride it, the more frequent the power loss. I am hoping that the battery just needs replaced, but I wanted to post here and see if there are any suggestions for other things I can check. I don't want to shell out for a new battery and have it be some other issue. Thanks for any help!
