My multimeter educates me that the voltage the the batteries and also they both review 5.6V. I know that through dropping below the 3V per cell threshold, the security circuit has actually kicked in and also is stopping me native charging the packs. Ns have additionally read that it is feasible to revive separation, personal, instance cells, by providing a "boost" v a small current, when the voltage is listed below the threshold.
My concern is this: is it at all possible to recovery the totality pack (protection circuit included) there is no dismantling it?
I only have experience through batteries native one supplier, yet in that case, once the voltage went also low the circuit was properly disconnected. If you room seeing 5.6V climate the defense circuit hasn"t actually reduced off access to the cells.

It is feasible that the security circuit isn"t preventing charging, yet that your charger isn"t attempting it.
I would try another charger. If that doesn"t work, I"d try to inject a small current right into the whole battery pack until the voltage it s okay high enough for your charger to it is in happy.
Maybe - v individual cells ns have revitalized them from under-voltage shutdown by injecting a tiny current with a center high value resistor from a strength supply greater than the cabinet voltage.
I have never attempted v a multi-cell battery.
It will rely upon the defense circuit. I supplied a few kilohm resistor fed from 8 or 9 volts come inject 1 mA or so till the defense circuit re-enabled.
