Now there's no warning. Thanks for the info. I'm going to try to get it to charge the rest of they way like you suggested!Well that shows it as good ...
What is the DJI Go app warning now ? Still there or gone ?
To get battery to 100% charge - that last little bit - switch on the battery when charging which then over-rides the default that occurs at near high charge state.
Thanks NigelCritical cell difference is when you get into 10ths of a volt not 100ths.But of course this may ddepend on what DJI battery FW decides.
LiPo's are used in so many models and there us a wealth of info online about them. Some so-called info especially on some forums is just rubbish but generally good.
A standard LiPo cell is 4.2v full charged with overcharged at 4.3v. But a DJI cell is what is generally called a HV LiPo, High Voltage ... which full charge voltage is designed at 4.35v. So far I have not found a reliable source to indicate the overcharge limit.
Normal cells 4.2 or 4.35 versions will show slightly different full charged results across a pack, not unusual to find it range up to 0.05v ... but if it ranged 0.5v - then you have a problem cell.
What can cause this ? Various factors, could be cells getting hard worked and degrading, could be high charge rate overheating a cell, could be poor balancing mode or even not using balance mode when charging. DJI have taken the step of removing from user control of charging. They have passed balancing and terminating charge over to the battery FW. Personally I do not like this but have no choice but live with it.
It is not unusual to find one of the inner cells going down first - it has less chance of dissipating heat and heat is one of the worst enemies.
The answer to the question therefore is 0.07v is not a nice number, but it is acceptable and worth keeping an eye on to see if it worsens. The 0.7v figure is bad and careful checking of charge needed to see why. If charger is good - then battery is soon failing.
Fly with care with such battery, look to replace asap and the first indications of course will be reduced flight time / performance.
Hope the above helps.
