I used the Zippy 4200mah battery for two activation’s over the weekend and worked fine.
Left the battery connected to the radio when I packed away.
Got the battery out to charge today and connected to the Turnigy charger.
Set to LiFe Balance charge, 1.3a 13.2v (4S), pressed start and got an error.
“Cell error Voltage invalid”
Checked voltage with a multimeter and got 5.5v? Also tried with a plug volt meter display that connects via the white multi-pin and that didn’t show any voltage.
Is it bust?
