RE: LIFE battery charging in the plane question
I run LiFe packs in 11 airplanes I fly from a 100cc Extra to my 54" Skyraider II Club 40 pylon planes.
Some planes I run dual packs, others single. On the ones I have the batteries buried I just add the balance connector extensions and Deans extensions and run them to an easy spot to access for charging.
Never had an issue or even heard of an issue with LiFe packs in terms of danger during charging like a Li-Po. And the safety aspect of the LiFe is why ALL my planes have them now. Only 1 plane in my whole fleet has a Li-Po and that is a tiny 2S on my 30cc Mx2 on the DLA ignition. But it is fully removeable for charging. I DONOT trust Li-Pos.
