Hello everyone! I have a Passport P1 Mini battery charger and an E-Flite 3S 11.1V 2200mAh battery. I bought these 2-3 months ago with the Night Radian (I had two batteries at the time) and after having an accident while flying, I was left with one battery, my transmitter, and the charger. When I originally first purchased the batteries, both were overcharged, and the charger told me CELL ERROR. After discharging them, the batteries started working and I flew. Skip to present day, and my charger is now leaving me the error CONNECTION BREAK. After some research, I assumed that the banana plug's cable was broken. However, I switched to the NiMa setting and tried to charge it. It worked; for a few seconds, the charger read that the battery had 1.2V or so. After a few seconds, the battery appeared to have 8.5V or so. I allowed it to charge to 9.1V and then returned to the LiPo setting. I tried to the charge setting, storage, and a few others. All of them gave me the message CELL ERROR. I then tried to discharge the battery and was greeted by the message CONNECTION BREAK once again. After trying the others, the same message was repeated. I went back to the NiMa setting and tried to charge it again, this time charging it to 10.1V. I returned to LiPo and tried the charge setting and storage. I got the error CELL ERROR again. However, this time, when I went to discharge the discharge worked. The discharge went until 9.59V and then stopped. I tried all the other settings and kept receiving CELL ERROR again. i tried this a couple more times and the same thing happened each time. What can I do to fix this? Thank you and sorry for the long question.
