How long are these Things lasting? I have 4 TP 1320 packs 2-dated 5-20-04 , and 2 are dated 7-20-04. I switched connectors about two months ago. I only had enough micro deans for my charger and 3 Battery packs. I used both LiPo packs from the 7-20-04 batch and one from the 5-20-04 batch. I have since been cycling three packs each trip out considering crashes . Meanwhile the other pack sits about 3/4 charged.
Today I put a new set of deans on the other pack. My heli RIPS again! More continous power. Longer run time.
The other three packs are OK but the one that has been sitting is Ballistic! It doesnt Bog nearly as much as the other packs.
I treat the packs well , They dont get that hot , and I have had Many Many flights on the Three packs. But I have noticed a decrease in performance after compairing the Batteries.

Has Anyone else noticeds a performance loss over time?

How hot is that hot?
Correct me if i'm wrong but anything over 150 or was it 160 degrees is slow death to Lipolies?
I heard that they are rated for 600 cycles,again correct me if I'm wrong guys.
I run my TP2100's till they just start to sag and land. They are alittle warm and my motor is cool as is the CC25.
I would think that after time useing them correctly they would eventually wear out but don't know how quickly they take a dive .
Give Thunder Power a call and ask them and let us know what they say.

Have you tried discharging them on your charger and charging them up at lower than 1C? A real slow charge? I have heard some guys doing that to try a balance the cells.
Hacker15L 9T is how hot they are getting? Does that mean it's a mild motor? I don't know Hacker motors.
