The constant "C" is only a multiplicative value of the amps. So-

5A pack charged at 10A = 2C

(Charge Rate)/(Capacity of battery) = "C"

Is there a charger for $100-$150 that will charge at 3C.I guess the first thing I should ask is what C can I charge my Flightmax 6 cell 30C 5000mAh packs at.I don't wanna charge at the limit so if 1 to 1 1/2 C is good,i'll stick with the charger I have.I just want my packs to last.

You can get a 150 watt Accucel from HK for much less than that, they also do a 400 watt lipo charger from memory but it had pretty bad reviews last time I looked, I think the 150 watt Accucel is only 40 - 50 dollars.

Chargeing a 6s 5000 at 2c (10 amps) is a pretty big ask, a 150 watt Im guessing will do about 6.6 amps I think.

Yep, I have the accucel 8, the 150W model, but it only does up to a 7A charge rate.

Turnigy AC8 is the one I'm getting.
Charging at 7 amp is three times what I can do now.lol...

You're going to hate your charger when you start charging 5000mAh packs.
5000mA is 5 amps so you will only get a 1C charge at best and I doubt it will do it.

I literally never use the word literally right.

I think you will find 6.6 amp or 7.0 amps to charge a 6s 5000 with a 150 watt charger is not bad, albiet not at 2c, I have a charger that will only reach 3.7 amps chargeing 6s 2650`s (Im guessing its an 80 watt) which is more than 1c but quite a bit less than 2c, I find it still only takes 25 - 30 minutes to charge them as a post to 1 hr at 1c, I wouldent go any smaller than a 150 watt for 6s 5000`s though.

My charger now is a Turnigy AC6 and it is a 50W charger.
All I get is 2.2 amp so 7 amp would be an awesome upgrade here.lol...

2650mAh 6S is also what I'm charging.

^ Im in the same boat, chargeing 2650`s at 2.2 amps with an Accucel 6 is excrutiating.

Luckily I still have my 80 watt charger, but the buttons have stopped working so all I can do is charge 6s 2650`s, I cant risk changeing the settings or I may never get it back to 6s 2650 ever again.

Appart from being 50 watt there great chargers though, Il definately be buying the 150 watt version shortly.

Flyhigh, if you are looking for good but cheap PWR supplies look into feathermerchant.com, he makes some nice server pwr supplies that are reliable, work good and really cheap. They are small as well which is a nice touch.

...Once upon a time there were Nitros, flybars and frequency pins...

I just converted a 500W PS from an old computer.
Works great.Tiny and quiet compared to my 270W Pyramid.

What about this charger http://www.hobbycity.com/hobbycity/...er_&_discharger ?Everyone seems to love the Turnigy stuff,its 200W and charges up to 10A .If not that one,I think this is the one you guys are talking about http://www.hobbycity.com/hobbycity/...lancer/Charger_(DE_Warehouse) ..

OICU812,
Thanks for letting me know about that,I found him on RCG.I have a brand new power supply I bought for a PC I started to build 2 years ago so i'll try and make that work first..

Those are both nice chargers and way better than what I have.

When you convert a computer PS,group all the RED wires(12V)together to get all the wattage and don't forget to put a load on the 5V rail so it won't burn up.I used a car tail/brake light bulb until a couple days ago and I then soldered an 8ohm resistor in the 5V line.

Take the black wire and the green wire from the main motherboard power bar and connect them together to make the PS think the computer is turned on.


Now find the square four plug lead.

Cut off the plug and group the yellow wires together on one lead...

And group the black wires together on the other lead.

Then there is a small group of wires that are labeled 5V on the board.
Put one red 5V wire on one side of a resistor or light bulb and one black wire on the other side.

You should have a good clean steady 13V power supply.

mckrackin,
Can you click the WV at the bottom of the post with the pics?Its next to edit and I can see the pics better that way.I understand what you mean about everything other than this part
Then there is a small group of wires that are labeled 5V on the board.
Put one red 5V wire on one side of a resistor or light bulb and one black wire on the other side.
I think your talking about the Motherboard connector,theres 3 that say +5V one that says +5 and a violet that says +5vsb..When you connect the green and black wire,does it matter which black wire because there 1 on each side of the green wire?

I'm pretty sure all the black wires are grounded the same.

I hit the WV button.
Is that like a West Virginian button to make pix simpler

Seriously,what is that for?

The 4020-1100 and more powerfull yet 4025-1100 works really well in the 600E, many have been using it and it is a fairly large improvement over the stock 600L etc. Can't find it at moment but there is a large thread on it and the rex 600E..

I ran the 4025 1100kv myself on my Trex 600ESP and it was a pretty good motor but not a huge improvement but I think I had the 600XL or 650L on my heli to start with.Don't remember now.

I would say it would be a big improvement over the 600L though.

Will the scorpion 4020 work on 6 cells with my CC 85HV esc?I really want the NEU 1515 2.5D motor but having to buy a new charger kinda killed that .I wanna run 6 cells for now and if I feel I need more power,i'll go 8 cells.Thats why I wanted the 85HV/NEU 1515 setup,could I run the scorpion 4020 on 8 cells?
