Lipo in my DX3R?

[JERRY2KONE]

Yea I also bought one of those 5 cell NM packs off of TH, and plan on using it for my DX3R. With the guts removed from the battery tray it fits easily, and I am going to use a simple Tamyia plug for easy hookup and removal. Plus I have some laying around and don't plan on using them for anything else. I still need to figure out how I want to charge it up yet, but something will pan out. I was going to try and use the installed charging plug on the radio, but finding a 6v charger with low milliamp ratings that plugs right up to the radio proved to be too much work for me. Plus there was a warning about the leads being designed backwards with the negative wire in the center of the plug. I hate when these companies do propriatory designs. The Lipo batteries would be kind of cool, but like BG stated not worth the chance of frying the radio in my opinion due to low voltage on the Lipos, or some other failure issues that are inharent with Lipos. NMs are just the safer bet for my efforts.

the charger I got with my DX7 has that warning and thy provided a 16hr charger for me to use....its not much more than a cheap wall charger you might be able to get a good deal on one online somewhere

U don't have to use that rinky-dink wall charger, i've been using the same charger i use for everything else and charge through the built in plug for 5 years now with no problem. I just cut the end off of the wall charger that came with the radio and got a deans pigtail, and put the negative radio plug on the positive side of the deans and positive on negative, works great.

Yeah, I noticed that too. I just rewired the jack accordingly to have a negative sleeve/positive center pin (which is the way it should be). Then, I just used a RadioShack plug (size N or M - can't remember exactly now) and it fit perfectly in the stock jack. Then it was just a matter of wiring a small extension so I can use any NiMH charger.

Yea I hear ya BG. I imagine that I will be doing the same thing with my DX3R as well. I guess since your radio is already done and in use, that it has not caused any collateral issues having the (+ & -) on the radio (charging jack)reversed? I will take a closer look at it this weekend and try to get it completed so I can start playing with my truck to. Thanks for the info Sir.

Like i said i have been using JR radios and the Spektrums since they came out (5 years total) using a made up adapter with no problems.

instead of rewiring the jack just swap the colors on 4mm bullets on the charge cord :)

Yeah, right! And the next time I just so happen to forget; poof!

Now how does that help anyone find the right charger for this radio? And like BrianG stated I want something that is a permanent fix for the charging of my radio, with no chance of mixing anything up and killing my investment. Switching the jack leads on the radio is the simple and final answer in my opinion. Then all anyone has to do is find a 6volt charger with the right milliamp output, that will plug right in.

There's nothing to mix up.

I decided to go back to 5 cells in my DX3R. I use Sanyo 2700 mah nimh cells. They are new and when peaked they pumped out 6.9 volts when I turned on my radio, then after a minute dropped to 6.8V and stayed there. BrianG I'm freaking out again

Sounds like a winner. I have the Hydromax 5 cell pack for mine. Now I just have to get the radio rigged up for direct charging so I do not have to remove the pack in order to charge it up, and then find the right plug in charger for it. I think it is a 2000 or 2200Mha pack.
