has anybody experience with this packs for the new programm. I use a Hacker
C50 14 XL comp with a ulsammer 21x14. How many mA do you use for the programm and how powerfull is this lipo.

Gerhard, did you buy these batteries in the end? What is your experience (or anybody elses?)

Do you mean these? Since you mentioned "New" TP4350, I have these for a while, so I'm confuse...

First quote is pretty old already, guess that is why. I am looking for packs that will help me make weight. I am now flying 4900 Rhinos which are 630 grams each. The 4350 Prolite seems like a good mix between weight and capacity. What is your experience?

It is a typical TP LiPo, good quality. I have them since Dec. 2009. 36 flights on first set and 24 flights on second set. Although I do not fly P-11, the AMA Master sequence used about the same amount of energy as P-11. See internal resistance records. I record my battery's IR once a while. They are stable so far.
EagleTree data was collected on 3/14/10, setup was Himax 6330-200-F3A outer runner, MPI 21x14 carbon fiber prop. One Master sequence usage is 3101 mAh. Before end of sequence the voltage was still holding at 34.6V, pretty good for 20C battery pack.
The key issue is your motor efficiency. I used about 3800-4000 mAh when running on AXI 5330/F3A and APC 21x14. I had to use TP5300 in this setup.

My opinion is 4350 is pretty marginal on capacity. The rule of thumb is to only use 80% of the battery to avoid stress in the pack, which is about 3500mAh. As the pack ages, say after 100 cycles, 80% is now even lower, so maybe you only have 3200-3300 mAh of useful capacity.

While you can certainly fly P-11 on less than 3500 mAh, I don't feel you can do it all the time under any conditions and there will be occasions which you will consume closer to 4000 mAh of the battery, putting it under a lot of stress and reducing its lifespan. I find that P-11 is actually a very long sequence if flown tall, which can really eat up the battery if you are not careful.

I feel that reducing capacity should be the last resort to getting under the weight limit. I think you will have far greater success in the long term with a larger pack like a 5000 or 5300 mAh that allows some reserve capacity, and try some other means to get under the limit.

I agree with Chad on the power consumption of P11. I consume between 3100 and 3600 on calm to mild wind conditions, and 4000 to 4100 on windy conditions. I love the TP 4350 pack because of its performance and light weight. But, I am afraid that it won't last as long as my larger packs because I repeatedly take it below 80%. I'll try the prolite V2 5000 for windy conditions. I am using the prolite V2 5300 now in the wind, but I think the 5000 would be better for my setup.
