As most know - the battery has LED's on the front that give Charge Indication, Life indication and condition. As I have mentioned before - the LED's work on a range principle and that range is too wide to be taken as accurate.
Example - today.
I have two batterys on charge for today, as weather has finally improved and I hope to fly later. I checked by LED and both had solid 4 GREEN LED's .... so you would think ... OK - full charge ... WRONG !
I checked both and one was at 16.68V and other was at 16.72V ...... that is IF cells are balanced about 4.17V and 4.18V per cell against the full charge 4.35V per cell.
Just passing on info ...
