Anyone tested these battery's?

[Paringa]

Yes, It work fine..

[Paringa]

Do you have any issue with yours?

More sensitive to cold temps

[RaceMechaniX]

I am running a 6S pack with very good results. I do always warm my cells before running. Don't recall what the IR values were, but decent enough to run in a 1P rigger setup.

More sensitive to cold temps

That applies to ANY lipo. Basic electrical physics. A batteries internal resistance is inversely proportional to the temp, so as temps go down the packs IR will go up and it will not be able to sustain the same output.

This is why you never try and fast charge or pull high current form a cold pack, otherwise run times will be shorter as the voltage sags quickly and damage can occur. Lipos are happiest and provide the best performance in the 80-100F range where IR is the lowest, yet still in the safe temp zone and not too hot to damage the battery.

Anything 60F or so and above will take care of itself as the packs will warm quickly in use, but I use a heating pad to pre warm my packs if running any of my RC stuff in the 50s or less.
