Quad charger question
 

Looking for a good one. I did some searching and get more confused about chargers the more I read. With 2 Yeti XL running 2 batteries each I need more charger.

Re: Quad charger question
 

You don't need a specific charger to charge 2 batteries at once. I use a Hobbyking ECO-10 200watt cheapo charger. It works, I'm not super fond of it, but it gets the job done.
I use a parallel charging board. I can charge up to 6 batteries with this board.

You hook up all your batteries, correctly, and select the amperage you need. Limited by your power supply / charger.

The power supply needs to supply more than the max amps your charger pulls. The ECO-10 charger is a 10amp charger.
My power supply is a 2zo-rc 47amp DC server PSU converted to power a DC charger. More than enough amperage.

When selecting how many amps to use, you add up the mah of your batteries.
If you have 2 4000mah batteries you can charge at 8amps for a 1c rating.
4amps for the 1 batt and 4 amps for the other.
The equation is the same for other mah.
2200 + 2200 = 4.4amps

You can charge higher than 1c ratings if your batteries can handle it.

Instead of multiplying your mah rating by 1 use a different variable. If your batteries can charge at 5c rating use 5.. ETC.

Hope that helps.

Quad chargers:

4x20 amp http://www.hobbyking.com/hobbyking/s...arehouse_.html

All these chargers I've listed are DC chargers. Meaning a seperate power supply is needed.
Commonly found are converted PC powersupplies. Cheap, reliable, easy to find.

As robertjpjr stated, Parallel charging is the way to go.

Not really, your limited to charging the same battery's. I can charge 4 different battery, 4 different cells and 4 different amp ratings. Or I charge 4 of the same batterys as a parallel one does. That's the way to go."thumbsup"

Built my set up for charging my 6s5000 lipos for my electric planes.
Dual 30 amps & 1000 watts is over kill for my crawler, but it's what I have on hand.
