My batteries never seem to last long. I quickly lose more than half flight time from a new battery,
So I just want some suggestions
If Im not flying for 2 or 3 days should I only charge to maybe 3.8v per cell then charge it up right before I leave to the field?
If Im not flying for a month or 2 should should I charge to about the same?
Any other suggestions to make them last longer would be great.

Posted this in a different battery thread, but it will probably help.

Conditioning a LIPO:
did something unusual. read the directions :-) The Venom battery actually came with instructions (in 5 languages, none of which were Chinese). That was impressive. Here are the interesting parts:
o may require 12 or more charge/discharge cycles to reach full potential
o during break-in time, keep discharge rate to less than 7C (explained this way)
- where C = battery pack mah/1000
- so a 3000 mah battery should not be discharge greater than 21 amps
- so on a 30C battery, during break-in do not exceed 7C! [how many of us have bloated batteries because we didn't know that]
o never discharge greater than mfg discharge rate (explained this way)
- where Rate = battery pack mah/1000 x C rating
- so a 3000 mah 30C battery should not be discharged (after it is broken in) greater than 90 amps
Battery temperature is critical (gives a wide range of charge and discharge temps so no issues there) but:
- store between 40F to 80F (4C to 26C)
- if cold outside warm the pack first to 100F (37C) [found that interesting]
There you go. Now if I can just find the lingerie store without asking for directions :-v
with Li polymer the longevitity is very much based on DoD or depth of discharge... And also keeping (over) charged for long periods of time.
