as far as i know when you charge a lipo in storage mode they do not charge right up they might go to 8.4 volts but that doesnt mean they are full as when you charge normally my charger will say 8.4 but still charge for a while after until the amps drop down. storage charge normally only half charges a battery hence storage mode so if you want to test them to there max set you speedo cut out to 6v run the car untill it cuts out then charge propely (but its not good to run them flat

)
