Hi rydfree, thank you for your comments.
I have tested many chargers and meters to get the best type and I have also done all the things
you mentioned but it comes down to the chemical reaction and stability and I never run them down.
Some comments are that you should NOT leave batteries fully charged and others say YES leave
them fully charged, so I did some testing of my own and fully charged ( all cells at 99% ) and left
them at room temperature for 3 months without touching them only to check the voltage once a
month and check for bulging and the results are NO voltage loss and NO bulging (thickness
measured every month). I took the same procedure with 2 other batteries but charged at 50% and
after the first month there was a 2 volt power loss and both started to expand slightly) so my
conclusion is that it is best to leave them charged at 99% so there can be no chemical reaction
as the chemicals are fully utilised
Someone might comment that it is wrong to leave them fully charged but from my point of view
I would rather have them ready to go and not buldge and pay the price for reduced life span of the
battery.
I also think that there is great uncertainty and unkown factors about Lipo batteries.
Cheers, JV
