Problem with Lipo batteries
Hi everyone, we are having problem in 3 Cell & 4Cell lipo batteries, their one cell went under voltage 1.5v & 2.1v. we are using IMax B-6 Ac pro charger. Please provide us some suggestion to solve the issue.
Expert advice will be highly appreciated. Thanks, |

End flight sooner and as a back-up plan set a LVC on the ESC.

If the charger will even do a balance charge, try that. If the charger will cycle the battery, start with a balance discharge, then a balance recharge. Some charges will not even start when the batteries are to far out of voltage.

RE: Problem with Lipo batteries
Once a li-po cell gets to such a low state of discharge, there's really nothing that can be done to get it back to anything like new. Cells can be recovered to a degree (I've done it!) but it's potentially dangerous as a fire is possible if great care is not taken. I managed to get the cells to take a charge by forced charging, but their resulting poor capacity and high internal resistance made the cell next to useless. li-pos are pretty cheap these days so throw out the damaged ones and take extra care of replacements.

RE: Problem with Lipo batteries
Are you testing the cells individually with a meter or are you going by what the charger reads?
Occasionally I will get a cell reading low due to poor connections either on the balance board or where the balance board plugs into the charger. Makes me wonder when you say your having problems in both a 3 and 4 cell batt. |

Dear, Thanks for reply. we have checked the connectors & those are ok. but having the problem as it is.
We have tried to avail charging by using NIXX setting, but result is zero. |
