Common Sense RC's Li-Poly TX Battery
one hear-say/verbal report said their TX lasted over 10hours. another one said well over 8 hours (not sure if these were deliberate tests). Aside from these reports, I had to replace my TX battery anyways so I though I would give it a try. We'll see how long it last this wknd!

2500Mah TX LiPoly @ I think it's max discharge is 4C

bought one but have not flown with it yet.... can say my "charger" smoked itself on the first plug in....so you might not want to get it. the battery fits great in the 8103...can't wait.

I've mesaured my Tx and the current consumption (with rf module) is 240mA, so 10 hours seems about right. I currently use my own pack which is NiMH 1800mAh. Predictably, I get about 7 hours.

If they aint holding charge for long, try cycling them properly. They should get a new lease of life.

Yep.... just bought some new RX 2700 nimh bateries for my helis.... charging them at .200mah for first charging cycles. Guess my problem is that I might not be flying enough to keep the life in them but when I was it seemed to last about 6months or so before I started loosing mah out of them. I did cycle them quite often though but I can't remember what charge rate I was using...might have been the max like a 2100mah battery I charged them 2.0 amps so that could have killed them off too soon....

You shouldn't really charge AA NiMH cells above 400mA

I had a 1600mAH NiMH pack in my old 9Z and charged it at 1.5 amps (after initial .1C charge), and fly several planks on similar 4 and 5 cell 1600 packs. Never had any problems with any of them.

I think you'll be really unlucky if you've picked up any decent NiMH cells for modelling recently and can't charge tham at at least 0.5C (though 1C would be pushing your luck)

i fitted a 1800mah 3s li-po pack in my tx some time ago after 6 weeks of flying say 1 hr a week i still have 12.1v reading

i tryed the same pack on a heli for the rx and a 5v bec and did a test
looking at a good 10hrs flying
the problem was a ni-cad pack at full charge is above 5v
so i found the servos a bit slower and had to turn up the gain on the gyro
so a 6v bec would have been better

a few specs
The 2500mah TX Li-poly pack that we're offering is rated at 4C. Hopefully , no one will try to use it for any application outside of transmitter use. Out tests indicated that transmitters, depending upon brand and model draw between 200mah and 250mah. That should provide 8-10 hours of use between charges. Since, Lipos have no "memory effect", it doesn't hurt to recharge them whenever it's convenient.

We recently ran a promotion on another forum offering these packs at $39.95 including shipping. (Calif. residents add 8.25% Sales Tax for Arnold). We extend this offer to the first 10 respondees on this forum as well.

I doubt that wire/connector will handle the max discharge rate of 10A for very long....

I received two of the tx packs today, cycled out at 2689mah (9v @ 1a). Unusual to see something cycle out higher than manufacture claim

Great company to do business with, fast shipping, and a quality product as well.
