The TrakPowers and Orions both have a smaller 2mm port in the middle that you use for balancing. Your shop should have an adapter or can get one to hook up to whatever balancer or balance charger you have.

A lipo charger and cc/cv are the same thing essentially. They charge at the chosen rate to 8.4 volts (4.2 per), then hold that with reducing current until completely full. Constant Current/Constant Voltage.

I was looking at the Trakpower V Blancer and it looked like it goes into the positive and negative wires and it would go into the charger where u put the + and - things in.

Dave H

Yes, but the battery harness also has a connector for the balance port, and a smaller plug for the small balance port on the battery. Then just 2 wires between charger and the balancer.

Well ya need to click on the V balancer page, then cell balancing, it will show you.

So are you just saying the I plug the wires into the battery and plug the other wires into the charger and it will balance?

Dave H

Yes as far as the wiring, I think you need to push a button on the balance unit before charging to get the balance charge. Check the V balancer manual. I have a balance charger in one unit, just plug it in and charge. Not completely sure about the double unit deal.

tell me this, if you dont have a balancer how do you know your packs are still balanced? i balance my packs every time i charge them it dont take any longer and that way i know they will always have a good charge and last longer.

+50 on trakpower, i use the 4800mah saddlepacks for my b44 and they are the nicest batteries ive used

im also buying a trakpower 3200mah 30c lipo next week

I had borrowed a balancer and checked it at 10 cycles and it was still balanced. Ive ran it 10 more times and just assume it is still balanced because it works great and I take good care of it!

orion and track power in my opinion are the 2 top packs you can buy. i use orion 4800 in my sp just cause it has a slightly thinner,shorter profile than tack power and i need that in the kyosho. the 3200 saddle pack from track power seems to be gaining popularity real fast with the d4 and b44 crowd.

Oh yeah by the way you won't be disappointed with your decision! Are you puttin it into a XXX-T? Ive only been running them in my touring car but off road starts in 8 weeks and I cant wait to run 10.5 brushless with lipo in a XXX-T CR!

Yep, I will be running it in my xxx-t mf2. I will be racing stock class.

So would the Trakpower 4900 fit in the xxx-t battery tray?

Dave H

Actually in my experience its quicker with a balancer. At least with the chargers I have, a Hyperion balance job and a couple of ICEs. Its finishes the cv portion much quicker, many others have the same experience.

Chris, as I understand it the 100/200 cycle thing is worst case, hard discharge all the way to 6v, with a very strict definition of performance drop off. If you only use 80% of the capacity the cycle life goes up quite a bit with any lipo. In any event I'm fairly sure its better than any nimh.

With a good lipo balancing doesn't seem necessary for a while, but I think it will catch up with us eventually. High discharges is one of the things that raises the risk.

Brand wise I think TrakPowers are most excellent. Orions are good too, and they have new better ones coming out.

Dave H

They fit great in all of our triple x Losis, an earlier XXX-T, and both truck and buggy newer CRs.

Was your second line a typo? I've been racing an early double x buggy for fun, for that I have to use an Orion 3600 to get it to lay flat. None of them really fit in my vintage JRx stuff.

I meant xxx-t on the 2nd line. So good that everything will fit good. Does it come with connectors where u plug in? Does it use bullet connectors or what? Can I have a link?

what i do is wire from the speed control to the battery with 4mm bullet connectors. no need for deans connector this way and a good solder job will not break.
