Solved Lipo charging problem

[badpilot27]

I just got my first lipo charger and when I tried charging a 2 cell battery with what I thought were the correct settings it was giving me the error "battery vol error cell connect" even though I set the charger for 2 cells.

photo right before it gave the error message

The battery is about a year old and I haven't charged it since I got it so that might be the problem but im not really sure.

the battery says 4.35 volts, are you sure it is 2 cell?

never mind, i see the 7.6v on the other side. odd looking battery

i think you're in balance mode instead of charge?

yeah im trying to balance charge it

I had that problem, your LiPo’s voltage may have fallen below the chargable voltage. Look on yt how to revive a dead LiPo battery. I am definitely not qualified to teach you how.

1.Use the tester to check the voltage on the battery packs connected to the balancing connector. 2. Charge each rechargeable battery pack in NiCd mode, using separate wires through the balancing connector, to a voltage of 3.8 -4.0 volts. 3. Connect the balancing connector and the main connector to the charger and charge in LiPo mode.All charges (even for phones) will not charge in LiPo mode if the battery voltage is below 3.7 volts.

Remember a LiPo cell dropped much below 3.3V will be internally damaged so such a cell will be weaker (have less capacity) than the others. The weakest cell always sets the usable capacity of the complete LiPo battery.

Take a close look at the balance plug. Make sure all of the connector pins are even. Sometimes one of them get pushed back & doesn't make contact. If so, just push it back in place & try again.

It's also possible one of the balance plug wires has broken loose inside the pack. Gently tug on each of the wires, one may come out with no effort. If so, you will need to solder it back on.

This battery is a LiHV battery. Change the battery type on the charger from LiPo to LiHV. It may not support that battery type. If it doesn't have that option, try a (genuine) Sky RC 6BAC V2 that has that option (mine does). It still may not work as the battery may be damaged. There are small battery testers that you can pug into the balance connector to see the individual cell voltages. These battery tester connect to the balance connector. Be aware that the connector will only work one way. It will not hurt anything if the tester isn't connected properly.

might be cheaper to buy a new battery and retire that one

It's a LiHV battery? I thought it was a normal LiPo when I got it but thanks for telling me. The suggestion that @Shurik-1960 gave worked and I can use my battery now.
