I need a new tranmitter pack and I'd rather not spend the $40 to buy a pre-built one. My radio requires a soldered-up 8 cell pack to be plugged into it (Old Hitec 3D which does not allow single cells). Can I use rechargeable 2000 mah cells such as those packs offered by Duracell, Rayovac, etc? Rayovac 2000 mah cells only cost $10 for a 4 pack of cells at my local retail store.

Are there any differernces between these cells and what comes with a Hitec or Futaba prebuilt pack?

i have been using them. the charger for your radio might be a nicad only charger. i use two wall chargers to charge my batteries. i also have a backup battery holder to charge the batteries at the track. i bought two 4 AA battery holders and stuck them together with servo tape and wired it so that i can charge all eight batteries at one time.

I use Energizer batters. 2300 mAh for my transmitter batts. They'll last several days.

They've never registered at more than 11v, they've dropped all the way down to 9v without any problems. But, I've heard others that have had problems at below 10v.

BTW, I use a JR Xs3 and Xr3.

I just got these myself. Energizers are now up to 2500mah for 8 for $16 or so. I just had to get them. I just pop them right into the TX / transmitter.

One question though. I have a 7 cell charger. How do I go about charging these?

Anyone got a solution?

You can use your rc charger, if you have one, for your sub - c batteries to charge your transmitter battieres. .5 - 1.5 amps should be enough.

Yeah I have a 7cell novak ionic charger. How do I charge 8 cells. Would leaving it set at 7 mess things up, should I pop out 4 and do it that way....does the battery tray in the TX need to have all 8 in there to make a complete circuit?

Man. I think Im having problems with mine. I have the energizer rechargable 2500mah nimh. Stuck them in straight from the pack into my TX.

Came up with about 10volts. Which sounds about right. After 2 hours I think it got to 8.5 volts and I got the battery low alarm.

I went to recharge them on 1.0Amp nimh took like just a few minutes and they were done. Werent even warm , the battery casing was though.

Did the other 4 about the same amount of time to charge. Put them in and got 10.0 volts. So im like ok they must charge fast.

Well 20 minutes later its battery alarm time. So im thinking something must be wrong. Im charging 4 at a time with a 4 cell receiver case that I had from my nitro.

I have a 3pjs and a novak ionic ac/dc charger. Are these run times off. I heard you get a lot of time with these.

Artificial I,

Leave the transmitter on for a while to drain the batteries a bit..Then recharge them..they more than likely need to be cycled (discharged and then charged) a few times to get the most out of them. New batteries never perfom well until you get a few cycles through them.

Yeah im thinking your right. They seem to be already at 20mins and still above the 10.1, this time I charged them a bit longer and when I put them in the TX. It read 10.5

Ill try draining them next.

usually the AA batteries want to be slow charged or trickle charged at a very low amp rate. Usually .2 or 3 amps is all and it should take an hour or two at least from the batteries being totally dead...

yeah, that's true too..slower doesn't hurt with these batteries

I have some Rayovac 1600 mah's that have been working for 2 years. Get a 8 cell holder and charger them at .5amp and you get more time from them. These are just now dying off. good value

I've been using the Energizer 2300's for awhile now in my 3PK and I love 'em. Charges up to about 11.2 volts and stays between 10.1- 10.9 forever, so there's no turning back for me...

Hitec makes an individual cell battery tray for the Lynx 3D (Part # 54405). I bought mine from Stormer Hobbies a couple years ago. I charge the eight cells with a Turbo 35 set at 1A with a .05 dropback (NiCd). You can probably use the same setting for NiMah just watch your temperature the first time. If they seem too hot turn the dropback to .04 or .03. The important thing is that your power supply must put out around 15 volts. A 12v supply won't work.
