so, I just got my plane back from it spending the night in a tree... the battery is a Kokam 3s 1500, it was down to 4.6v overall after recovery. On my vision peak charger, I tried it on lipo, and it only went to 8.4 like it thought it was 2cell. so I hit it with nimh charge for about 30sec, brought it up just over 9v, then hit it with lipo charge again. pack charged all the way up, but overnight dropped back to 12.15v.

after reading this thread, I went and cut off the casing, and measured the individual cells, getting 4.04, 4.04, and 4.03. Does that mean the pack is still safe to use?
