I have a JR 6102 with the original batteries out of the box. The 1100mah Rx and 600mah Tx NiCD batteries. Do you know if you can get lithium batteries for this radio or NiMH and if so what are the best for it?

Duralites are a great setup for your gear.

I know that this is heresy on this forum so my flame suit is on. I must be dense because I still don't get it. I have Duralites in my helicopters and they're great, but I see no reason to put LiIon batteries in transmitters. Duralite batteries for transmitters are 1300ma and cost over $100 not including a charger. A 2100ma NiMh with quality Sanyo cells can be purchased for about $32. Yea, I know, I'm just stupid.

Bob,
Your not stupid. The reason I suggest they go Lithium Ion with everything is so that they just have to have one charging system. Yes I know some of the chargers do Nicads, nimh, lead acid, lithium all together. But it lessens the possiblity of setting up the charger wrong if using an after market charger.

Bob, Please try to look at it from my standpoint. I work a buttload of hours, My playtime is generally rushed, squeezing in a hour here, and an hour there...
Having the ability to plug and play one charger to up to 3 heli's and one transmitter leaves a whole lot less room to screw up.
Plus knowing that it can't be set wrong is a big, huge plus. Hook it all up on the run and forget it, it's ready when I am.
Okay, I'll admit I'm lazy as hell when it comes time to play, I want instant gratification and to be honest I have a small pile of stuff waiting to be fixed, and a larger pile of stuff waiting to be built.
There are other options, there is no dispute about that, If NiMH technology is worth the additional time to keep up with different chargers, and the dollars versus capacity is worth it, so be it. Me, I'll spend the cash and run the easy stuff :D
I use NiMH in the transmitter since the load is very small on the battery. They seem to work quite well.
With NiMH the voltage warnings stay the same, and I think you have to stop flying on a LI pack at about 10.5, which would be quit a bit more than on a nicad ot nimh, correct me if I am wrong.
As far as congruency in charging, With the triton, it really isn't that big of a deal. Memory 1 is the Sceadu, 2 is the Vigor, 3 is the transmitter, and 4 is the starter battery (lead acid).
I guess it is all about what you like.

The reason I started this whole questions is cause I have that original Tx battery and it does not last very long. I had my hobby guy call JR and they said you can't run lithium batteries of any kind in these radios. Now I'm just confused.
The reason JR says no to Lithium is because the lithium cell has a higher voltage than a typical cell. 3.6V as compared to 1.5V. Thus there is no Lithium combination that will directly fit the design specs of radios that were designed for NiCd.
If I understand it correctly, the 14MZ (Futaba) uses a lithium pack, and it would naturally have a different voltage allowance than a NiCd design.
NiMH packs have the same voltage per cell, so they fit in the transmiter voltage range well, and since the Transmitter doesn't have a high current, the NiMH does ok (they don't have a very high working current due to high internal resistance)
This is not to say that you can't use a Li pack in your NiCd design transmitter, but I bet it will void the warranty, and you will have to keep a close eye so you don't over discharge your Li pack.

LynyrdSkynyrd,
This guy sells a NiMH pack that can't be beat. 2700mah. Your 6102 likely uses the black JR connector, but check before ordering.

I use one of his packs in my 9303. A great deal at less than half the price of a duralite, it's twice the capacity. No special charger required.
Lithium batteries, such as from Duralite, will work. JR can't recommend off-standard things, so they just say "no" to everything. If you really want to use Lithiums, the Duralite stuff will work. Don't forget to buy the special duralite charger.
