Thanks for posting your detailed data that may help others!
Your data and observations are similar to mine:
The capacity of my LiPo was also temperature dependent.
After about 120 re-charges (1A charge current) over an active lifespan of less than two years, it had about 30-40% of it’s original capacity, at about 10C environment temperature.
Mostly, I used only 70% of its capacity before re-charging. I used the LiPo for about 4 times until it switched off by itself. This is probably bad for its lifespan.
Usually, I recharged it just before I did an activation.
When using LiFePO4 batteries, I could not experience a capacity drop with low temperatures. From what I read, one should not charge this chemistry below 0C, but discharging at low temperatures seems to be OK.
Hello,
Just to confirm…
I use Windcamp Lipo, for at least +/- 10 years and more than 1000 activations.
On activations, i keep having QSO until no more power and charging it when back home, ready to go again.
I used 5 of them, since! With the 3 Amps, i can do about 100 Qso cw/ssb.

The original one that was part of the package is a 2A 12.6V LiIon/LiPo charger, but I use another one with only 1A max. current. Of course, I could also use the universal iMAX B6 charger.
@DH8WN i used and still use the original charger 12.6V 2.0A
I used 5 of them, not parallel… just because they lost the capacity.
i still own 3 out of 5, that means they last around 4 years and more than 200 activations.
For now, i think i’ll probably get an external accus from hobbyking 3S 5.0A (cheeper)!
Ps: i’m no sure i will be able to climb summits another 10 years (getting old) hi!

Has anyone disassembled his Windcamp battery pack and knows the type of the cells that are used? It shouldn’t be too difficult to replace them with new ones.
I don’t want to cut up my battery pack while it’s still good…
