I have a .40 size Wildcat profile with an 1100 Life pack in it that has 4 seasons on it now and still works flawlessly. Perhaps it is time to change it just to be safe. I wanted to try Life in a simple airplane that i didn't have one year or more of building time. So far so good. I have always charged through the switch harness so i don't have any idea what is up with yours jak. I have never been a big fan of Nimh. I still have a lot of planes with Nicd's, the good old traditional packs. Going forward, i will use Life on larger more complex subjects but due to the fact these packs only have 2 cells, i will use 2 packs and 2 switches for redundancy, which is not a bad idea on any plane. If one cell fails on a Life pack and you only have 1 pack, well, the rest is history.....
