Never noticed this number (38%) before. What does it mean in relation to the battery charge number 91%?

That number indicates the total battery life span. At 38% that is very low for a pack that only has 21 Times Charged on it. Unless you do not let it go below 50% before you charge. If you do not go below 50% before you charge the counter will not register it as a charge. How old is that pack? If you have only flown it 21 times something is wrong.

This was my first battery and yes, I did not let it go below 50% before charging (before I learned how to condition my batteries. This one is 1 of 5 so I'll probably just retire it. Thanks.

Did you condition this one? Drop it to 5% then charge back up?
Cell voltages are pretty close and if cycled they might be better.
I would expect it to have more life yet

Dave that's a good point but can you clarify the process?
If the battery is used to say 60% left then charged and this is repeated say ...  20 times.
What would charged number be?
zero?   8 ?
I thought it accumulated percentage of charge   as in example above   40% charge 20 times = 8

OK that's good to hear. I was worried about your pack for a minute there.

If that is all you did the number would be zero.  The times charged counter will not register a number unless you are charging from somewhere below 50%.

Does that battery give that life reading all the time. It certainly shouldn't be 38% after 21 charges.This is one of mine, still 98% after 55 charges.

Popped the battery back in, haven't done anything with it since last check, and now shows 94% batt life and 29 times charged...

Good to know. I knew there was no way it would have less than half it's life left after so little charges.

It is odd that it is fluctuating that much....


Dave

Ok thanks Dave
Pilot , It is strange to fluctuate. What does the history show between then and now?

only one abnormality.

Well but doesnt this have effect when flying??


We have seen here one time the battery showns 3200 capacity put it in again it shows 4200 capacity? Do we even know the real capacity now?
