Hello,

I have three Mavic air batteries with low cycles (less than 10):

Do you think any of the three batteries below will achieve good battery health afterwards or is it already clear that all of them are permanently damaged and will no longer be able to keep a charge?

Battery one: (no response via EV2400)

1. cell 0.705 V

2. cell 0.965 V

3. cell 0.504 V

Battery two: (no response via EV2400)

1. cell 1.354 V

2. cell 1.804 V

3. cell 1.861 V

Battery three: (read-out via EV2400-NLBA, then went silent)

1. cell 3.131 V 

2. cell 2.943 V

3. cell 2.157 V

The above voltages were measured manually with a voltmeter after opening the batteries. 

Only battery three responded to the EV2400 / NLBA interrogation (voltages: 3.152 V, 2.968 V, 2.084 V read out yesterday via software) but it showed "locked, bad balance 1068 mV cells 1-3" and later the battery no longer responded to interrogations, I believe the voltage dropped too much preventing further interrogation. 

I would have to charge all of them manually and every cell individually. The issue is, in order to "rescue" them, I'll have to get a lab power supply and a DJI license for NLBA and I'm wondering if it's worth the trouble and the money? Should I remain optimistic and give it a try or would that be foolish?

Thanks.
