Status: offline 		Hi Danny,
A number of battery suppliers are offering Li-Ion batteries for transmitters. I am considering use this type of battery in my JR9303 transmitter. The batteries operate at approximately 10.8 to 11.5 volts. Assuming I keep the battery charge rate to a reasonable level (300mah), is it safe to use a battery of this voltage in a transmitter that was designed to operate at 9.6 to 10 volts? Thanks for your help.

While the site is presently closed Danny did answer similar questions a number of times in the past.

Do a search and you'll come up with his answers which, as I remember it, were "Not recommended".

LiPo still is a magic word for some
If it is LiPo -or LiIon -it must be better . (it ain't)
I have had people tell me their 2100 LiPo lasts longer than a 2100 NiMh
The problem is -it is true -
but not because it has Mo Powa. (amps is amps)
It simply does not self discharge as fast - better shelf life n flatter discharge
LiPo is not a good choice as a TX retrofit - as a reg needed that is another problem point. more component changes -more potential problems

Best bet - just add the new camera Nimh cells - terrific shelf life -(low self discharge)
and no reg change nor new charger req'd
SAME power as the 2100 LiPo and cheap!!
Want latest technology with best bang for the buck and best safety for yer model?
use the new camera cell in the tx and A123 for rx pack (the A123 does require new charge tho)
The future is now

x2. And you can actually get a Dapter and use a nicd charger for the A123 for $40.
