Problem with Hydrimax battery

The JR batteries I think they all have three leads one yellow, red, and black, the volt reading is between the red and black, I also have a Hobbico re cycler, I had to get a JR charging lead from our LHS to charge JR with Hobbico charger.

Was this charging lead for the receiver or transmitter battery?

By the way I got the charging leads for the both, TX RX charging leads, but I think he is refering to the RX battery problem.

What charger leads did you buy?

That was JR leads, reciever leads and transmiter lead. All my other radios and transmiters are Futabas. I only have one JR system.

Manny,
Don't worry about the white wire, It just ends inside the wrap on the pack. It's nor connected to anything. You probably just have a bad solder joint on the red or black wire inside the pack. While I'm at it, I wouldn't use a Hydramax pack with digital servos or more than 4 or 5 analog standard servos. They have a high internal resistance and voltage drops dramatically with a load as low as 1 amp.

Well, I called Tower and they are going to send me out another one. They told me to throw away the battery. But, of course I did not. I open it up and saw the that the black wire was cut by accident. It was laying at the edge of the battery and was cut. I found out what the white does. It does nothing. It is not hock to anything. It is just laying inside. I am going to solder a new wire on the battery and it will work.

Glad to hear it's resolved. When you're soldering the new wire, be sure that you don't overheat the battery, it's possible to damage it. If some of the black wire is still there it might actually be better to splice the black wire than removing it from the battery. If you go this way, be sure to put some shrink wrap or tape on it as insulation.

Thanks guys for all your help. I got it fix and I have a new one on the way. I was not going to open it up until Tower told me to throw it away. I am charging it up to see if still has the capacity. It had hardly any charge left so I do not know if this battery is good anymore. It had around 4.0V left so it should be good. We will see. I am doing a slow charge on it so I will not until tomorrow morning.
Piper Chuck, will this battery work with digital servos like dubya_o said?
Thanks

Manny5150,
There shouldn't be any reason why you can't use this with digital servos. I'm not sure why he would say that you can't use this battery with digital, unless he is referring to the capacity of the pack itself. Digital servos draw more power than a standard servo will. How much capacity does this battery have??

It is only 1650 mah. I do not know why he said that. Tower website does not have any warnings about this battery. I have heard good things about these batteries. That is why I purchased it.

I've yet to feel the need to use digital $ervo$. Bear in mind that there are a variety of hydrimax batteries, some from Panasonic, some from Sanyo. I've read comments about avoiding use of NiMH batteries in high current setups due to their higher internal resistance. If you will be using a high current setup, such as dubya described, it would be a good idea to test the voltage while under load.
You've got an Accucycle Elite, do some discharge tests at varying loads and see what happens. If the voltage drops too low, you've got your answer. When you're done, report the results here, it would be interesting to know.

I know this off the subject, but I have a dilemna
. I have a an extra OS .46AX, receiver and five standard servos just sitting around and waiting for the perfect plane. What do you suggest?
Piper Chuck:
I will try it out. I am cycling the battery right now.

Kidding aside, provide a bit more on what your experience level is, and what kind of plane you are thinking about and you'll get LOTS of opinions.

I have been flying for a year, but I still consider myself a beginner. I have four planes, but I have only flown one of them - Tiger 2. I will be flying the SSE and the Javelin in the next few weeks. I was thinking of the GP venus.

Manny5150,
Well now, that is a dilemma isn't it. Very very hard to resolve. Hmmmm, I'll tell ya what I'll do...... Send them to me and I'll put them in a plane here!!! That way you don't have dilemma anymore do you?????

Seriously though, what kind of plane are you looking to fly with next?? There are several that leap to mind using what you have. [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXFG18&P=0]Sig Something Extra[/link], [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXFG06&P=0]Sig 4-star 40[/link], [link=http://www.greatplanes.com/airplanes/gpma0240.html]GP Ultimate[/link] (if you want a bipe), [link=http://www.greatplanes.com/airplanes/gpma0180.html]GP RV-4[/link] (I got one of these for Christmas, looking forward to building it after I finish my Decathlon), [link=http://www.greatplanes.com/airplanes/gpma0390.html]GP Ultra Sport 40[/link] , [link=http://www.greatplanes.com/airplanes/gpma0492.html]GP Slow Poke 40[/link] (I have one of these that I had 26 hours of flying time on last year. Very fun plane), [link=http://www.greatplanes.com/airplanes/gpma0480.html]GP Dazzler[/link] . I'm sure there are more that will add to this list, but these are what jump to mind right off the bat.
Hope this helps
Ken

Other than the fact that JR connectors don't have a polarity tab, I don't think there's a difference. However, I recall reading that the JR tx charge plug has a different polarity than Futaba.

By the way I got the charging leads for the both, TX RX charging leads, but I think he is refering to the RX battery problem.

These guys are making pretty nice ARFs, good hardware packages too. I have the second one & she's a beauty!!

Capacity has nothing to do with why I won't use these batteries in a higher load situation. I have 2 of these packs with Sanyo cells , a 1100mah and a 1650 mah. When I load test them the voltage will drop to @4V with a 1 amp load (4 cells). If you have a digital servo bind up in flight it will put more than a 1 amp load on the battery. This will not be good.
If you have a 5 cell pack you could live with the voltage drop because the battery won't drop to the point that the receiver quits.
