Default Transmitter LiPo or NiMH

Does anyone know who sells LiPo battery packs and associated voltage controllers to replace my Nicads in my transmitter? How about NiMh??

Go to this page...
http://radicalrc.secure-mall.com/sho...20&cart=365111

scroll down about 1/2 way and there is a battery with 2500 mAh


lasts for HOURS and much cheaper than a lipo
(someone posted a link before, but if I remember, it was over $50 for the battery)

If you contemplate using LiPo in your transmitter, be sure that you can monitor the voltage under use to make sure it does not drop below 3 volts/cell. Also, for safetys sake, you need to remove the battery from the transmitter for charging unless you do not value the transmitter or its surroundings during charge.

I put a 1650 NiMH in my 9C and I can fly all weekend w/o recharging, a magnatude cheaper than LiPo and much less hastle.

Might I suggest that 3v per cell cut-off is too low for a LiPo used in a transmitter? It may be appropiate for a pack used in propulsion at 5-10C or more, but at the comparatively low currents used in a transmitter they will drop very little voltage. I think 3.5v/cell is a safer limit. If the pack recovers to 3.7v/cell or so after cut-off and resting, then you have a safe limit.
