hey guys
i got up today to charge my lipos i got 2 of them 3600 and 4000. I have a venom pro charger and it keep comming up Battery Vol ERR cell low vol(see picture) when i go to charge them
my battaries still look in good order so i dont know why its hapening
so if anyone knows why its hapening and how i can fix it. would be great help

cheers Dean.

The cells are at lower voltage than the charger will pick up. They maybe damaged. AT YOUR OWN RISK you and charge them on ni-mh just less than a minute at 3 amps to try to bring the voltage up to spot where the lipo mode will pick the up.

Your lipo has been overdischarged. The voltage has dropped below that set as the minimum voltage the charger will start charging at for a lipo. If the lipo is in good condition (not puffed), you can charge by settingthe charger on NiMH mode and charging at 0.5 - 1.0amps. Charge it onlylong enough to get the voltage back up over 6v and maybe a little more (6.1-6.2v). Monitor the lipo and stop immediately if it starts to puff.

As soon as voltage is back above the minimum, stop charging as a NiMH and change to lipo mode. Charge it normally, but watch for puffing. If it doesn't puff, run it. Check for puffing as its being discharged. If yoiu don't see any puffing, the lipo wil prob be ok.

You shouldn't discharge a 2S below 6volts. Use some kind of low voltage cutoff. Overdischarging will at the least damage them and cost you some batt life. At the worst, it will puff them and ruin them.

thanks guys
none of them are puffing and all working in order again

cheers all

This worked a treat much appreciated.

took seconds for it to get to a voltage that could be read by the charger.

Cheers
