Hi all,

Having heard so much about the Polyquest XP recently I purchased a PQ 2S 2100 XP pack from www.aircraft-world.com (http://www.aircraft-world.com) and ran a 7C discharge measuring the temperature change during discharge. As a reference I compared to a similar pack; the Thunder Power 2100 2S Prolite. The PQ XP appears to deliver better Wh capability throughout most of the discharge.

The results look interesting (see graph below); so much so I will take it into the lab and carry out some controlled testing up to 16C discharge. Are there many of you guys using these new PQ packs in your models - how is the pack holding up with time?

That agrees with the TrexTuning test data. Don't own any yet but they will probably be my choice the next time I buy cells. I'm glad you added that battery to your tests.

2S 2100 TP PL weighs 95 grams and PQXP 2S 2100 weighs 125 grams. I guess a little over 1 oz. or 32% more battery weight does not matter that much to some. I find that increased battery weight requires more throttle on average for the same flight performance and the extra weight often results in shorter flights at reduced overall performance.

Iíll be interested to see your results RC-Tester. I agree with Charles that weight is an issue but I know it is hard to find packs of different brands with very similar weights and capacities

I too agree with Charles. I favor less weight over available watts out if I have to choose.

Thanks for posting RC. I look forward to your results. :)

Rod,
Glad to see results other than TP and Kokam. Any chance to test Tanic?
Thanks for all of the great work,
Neal
