    Default Hyperion Batteries

    Has anybody had issues with hyperion batteries ? I bought set of the 4S ones they were offering on the website. They have only lasted 3 laps plus a 1/2 lap mill. Anybody else experiencing this activity. I have tried to contact them to return them but get no replies to the website or emails.

    No issues, I have both new and 10 year old Hyperion cells that still work great. Do you have a battery ESR checker or do you have internal resistance measurements on your charger?
