My 2 sets of TP5300's have 110 and 115 cycles on them now and don't seem to perform any differently now as far as flight performance other than they come down about 5 -10 degrees hotter than before. That is still only around 120-130 degrees on even the hottest 95+ degree days. Don't own a generator either, just a $110 deep cycle marine battery that gives me 5 full 10S charges per session. That is just plain inexpensive power. I come to the field with 3 fully charged packs and I am good for 8 flights. Much more than I will typically fly. Keep the info flowing Don and Jim, there are plenty of us out here who appreciate the data.
