I would look at something else. I am on my second set of 3S 2200 Extremes. The first were warranty exchanged. This set has 22 cycles each, and they are losing power already. My next batteries will be Flight Power 3S 2500's if I can verify that they will fit.

I just started using KongPower 2200 4S. Seem to be comparable to the FP packs but to me seem to deliver a more constant supply thoughout the flight whereas the FP seems to fall off.

hey
i would say if you want duration that the Air Thunder batteries are the only way to go

all others you have to obey the 80% rule, but with airthunder, you typically put back anywhere from 95%-100%!

i flew my t-rex HDE XL a couple of days ago on the 2200mah 11.1v Air Thunders and got 14 minutes of sport flying

check them out: Single Battery

Two Battery Special

enjoy...happy flyin

Thanks

Maybe the KongPower Packs use the same cells then because they are also not bound to the 80% rule.

Should be noted also that the air thunder disclaimer warns not to overdischarge intentionally.

Air Thunders have Amazed me!

(Trex 450 SE V2 and 600E Pro)
I've flown several different packs usually with the timer set at 6 minutes of sport flying (still a noob with mucho hovering also) and with most packs, I'm down to the last 25% which is almost time for a recharge but with the Air Thunders I'm seeing numbers like 40% left or sometimes even higher. Also, let's not forget with these packs, you don't even need to time your flights. Fly until your feel a noticeable decrease in power to the point is won't stay in the air and then land it, cool it and charge it.
I really like them and probably won't be running any other packs unless somebody gives them to me for free.

One last thing, the customer service from Air Thunder is second to none in this hobby!
Respectfully,
Ed

Gary-theres three main ways to get longer runtimes.
1) Lighter heli- takes less power to keep it in the air
2) Bigger battery- more gas in the tank = longer flights
3) Lower the Amp Draw- any number of ways
a) Remove all possible drag from the machine
b) use a smaller pinion-reduced headspeed but less draw
c) shorter blades- won't make a difference if only hovering
d) make sure the gear mesh isn't too tight
e) make sure belt isn't too tight
f) check the mainshaft- if the collar is too tight to the
main bearing it will bind some
g) different motor-that draws less amps it may not be aerobatic
but will fly longer
h) oiled bearings will rotate more freely than greased- but
you will have to oil more frequently

If you skip me I can't play!
