Anyone have a link to charge leads that will work to charge my venom 1200 hump pack with with my duratrax piranha ac/dc digital peak charger-- I also want leads to charge my jr xs3 transmitter which has 8 nimh duracell 2500 mah rechargeables in it - Trying to get my savage le to charge the recvr pack without pulling apart the box-- Already have the 3 lead on/off switch and I am going to run the wire out to the roll bar and tape it for safe keeping.

Dont know anything about this- but how about charging a glo-ignitor with that charger-- I hate those crappy all nite plug in chargers.

I see this on tower- but im not sure if it will work?- Dont know if my charger takes those bananna plugs?

I run a similar setup (charger, radio, etc). I built custom wiring for most of it. If you have a soldering iron, a friend (or a bench vise if no friend is available), and some needle nose pliers, you can too. The standard stuff that comes with R/C cars and batteries is a nightmare waiting to happen.

Radio:
Remove your battery clip from your radio and use [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXL338&P=7]this[/link] to charge them. Clip the alligator clips to the positive and negative terminal of the clip. I try not to exceed 1amp when charging, because you don't want to overheat and melt your radio clip.

receiver pack:
If you already have a 3-way switch, I would highly recommend buying [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXDKA2&P=ML]these[/link] to replace the stock connectors. The stock ones have poor current handling ability, and melt easily. Using these cheap micro Deans plugs is also nice because they stay together better, and handle current much better. Solder one set onto your receiver charge switch, as well as a matching one onto your pack. Then put the opposite one onto the side of the switch that the battery connects to, and the other opposite one onto a set of charge leads with banana jacks. This way, your charger lead can be connected to either to the battery or to the switch. Spend lots of time checking to make sure you have the right connector in the right place, so you don't make a mistake and have to unsolder and re-solder somewhere else. If you don't want to solder together your own charge leads from scratch, you could buy another set of aligator ones like those above, and just cut off the aligator clips and solder the Deans plug on.

glow ignitor:
I just run one of [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXL337&P=7]these[/link].


EDIT: JR uses reverse polarity on its charger for the radio. So if you don't use alligator jacks like I mentioned above, make sure you wire up your radio connector backwards.

ok- thanks for the info- It definitely is do-able then..You didnt mention what charger you had....

I guess my question still remains will this setup work with my duratrax piranha ac/dc digital peak charger? I have only been charging 7.2 flat pack nicd and nimh batteries so far with it. Will this charger take those bananna clips? Looking at it, it looks like the old speaker wire connect which takes bare wire. Im not a battery guru so I dont really comprehend the difference between AMPs and Volts. I just dont want to hook it up and fry something!

Thanks-

Yeah, I have two chargers, the Duratrax Pirhana Digital that you have, and the MRC Super Brain 977. The Duratrax will take the banana jacks into those speaker terminal style connections. All of what I listed above works with either of the two chargers I have. Sometimes I get an error plugging the glow charger lead I gave you a link to saying "open circuit" though, when it does that, I switch over and charge my glow ignitor with the MRC charger. I don't know why sometimes the Pirhana gives that error and sometimes it doesn't.
