Can someone point me to a rechargeable battery pack for the LST1 stock transmitter if there is such a thing, it's the JR XS3. That thing mows through regular alkaline batteries like there is no tomorrow. I did a search here and didn't come up with anything.
 
I don't mind doing the soldering, I'm not set up for lipo yet and can't spend the money for a suitable charger right now.

Thanks for the help Rob, I believe that thread has the info I need to modify my transmitter.
 
Well, you could just buy some decent AA NiMH cells at wal-mart (I use duracell 2500Mah cells) and buy this: http://www.horizonhobby.com/Products/Default.aspx?ProdID=JRPC223

Granted, it's not a "quick" charger, but it's at a low enough current that it will help the cells last quite a bit longer than those harsh quick chargers that they sell in normal stores. IMO, those chargers that come with batteries in normal stores charge the batteries until they are far too hot. I don't know what Mah rating they burn at, but it seems to be a bit too much to conserve time for the buyer.

I've found that charging mine at 500Mah makes them last a lot longer. Both my receiver packs (2/3A 1100-1400mah and AA 2500Mah) and my transmitter hold up really well to a 500mah charge. I've used 1.5A to get them juiced up the first time, then after they peaked, I let them cool down and hit them at 500mah. I then use 500Mah before I go bash the morning of or night before to top them all off.

Been working well for me for quite a few years.

I've done the receiver plug pigtail mod on my remote in the past (Airtronics MX-3) and I use my MRC 959 charger to charge everything. Except for my heater cells.

I recently picked up a Spektrum DX3.0 which uses the same charge jack as the JR radios. I had bought the JR charger similar to the above one 8 years ago, but it was for NiCAD and was a lower Mah rating. I just cut the end off of it and wired it to a receiver pigtail and now use my MRC959 for it as well.

I even use my MRC959 to charge my 12V drill... does a heck of a lot better charge than the B&D wall charger it came with and in 1/4 the time. Almost made my drill feel new again!

EDIT:
I found a better one that charges 500-700 mah. Appears to have a switch: http://www.horizonhobby.com/Products/Default.aspx?ProdID=JRPC221
Costs a bit more, but would cover you for receiver packs and your transmitter. Not sure if it can do both at the same time... doubtful.

EDIT... AGAIN!:
Found another that runs at a higher charge rate yet: http://www.horizonhobby.com/Products/Default.aspx?ProdID=JRPC222

Honestly though, I'd go with the 500-700mah one. Buying both would be silly unless you want to charge your receiver and xmitter at the same time. Otherwise you could just get a charger like mine and do a bit of work installing a pigtail on your transmitter.

Mines outdated, but they have a MRC960 now: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXRST9&P=ML
You just have to remember to always drop down the charge current before hitting start. It defaults to 3 amps which is way too much for AA's. Like I said, I set mine to .5A (or 500mah) and it works well.

Man... I'm a jabberbox!

Who cares, that's some good options, the more the merrier as far as I'm concerned. I have some decent 2500mAh Enegizers, I bought a charger for them, does 4 at a time, takes 15-16.5 hours to completely charge them, so I think it's doing it at a pretty low rate.

I think you're right, the 'quick chargers' get the cells WAY too hot and I had a lot of failures with that type of charger. It would do 4 in 15 minutes and you could barely touch them when it was done.

2500mah in 15-16 hours runs around 150mah charge rate.

Yeah, those were the types of chargers I was talking about. I bought one of those 4 cell packs with charger. I tried it just to charge the 4 cells for my camera... once I realized how hot it got the cells, I quickly found some 4 cell AA receiver pack battery holders and now I use that with my 959 to charge them.

I also made a holder for 2 cells. Since my camera uses two at a time, I now am able to just charge two at a time or, charge 4 for backup on bash day and top off the two in the camera before I go.
 
Another member posted a picture of a Lipo pack that has the positive and negative terminals already on it. It looks like it would slide right in and work.
