Dual Battery Charger.
OK, I'm tired of parallel charging and want to get a dual battery charger. It turns out that at the field, charging two batteries at a time, and not 4, is the best way to always have a pack ready when it is my turn to fly.

I also want to make sure the batteries are balanced better than is possible with parallel charging.

I want something that is easy to use.

Something that is intuitive.

Something very easy to use.

Something of high quality.

Something that is instinctive even for an old guy like me.

Something that balances packs very well.

Did I mention easy???

Thanks guys.

The dual channel chargers on this page are a good place to start http://www.progressiverc.com/chargers/battery-chargers

Personally, I prefer to setup the charger (options, and presets) using a PC. Then save that to the charger. That leaves only one from that page.

I really like my Dual PowerLab 8x2 (DPL8). I've had it since they first come out in early December 2013. Prior to the DPL8 I used two PowerLab 8's (early v1's from the first/second batch) and never had one fail on me.

I find the user interface straight froward and easy to use. The default presets are perfect right out of the box.

The free Charge Control Software (CCS) is a great bonus that allows you to customize the charger settings, perform firmware updates, manage presets (if necessary), and graph charges/dis-charges.

Another vote for the DPL8...

I agree about the factory presets, I haven't even bothered to learn how to set up my own yet...too busy flying the ones I have charged.

Revolectrix.com, HeliDirect, Progressive RC, and there are a few others that carry them.

I have a question regarding the OP's reluctance to do a parallel charge. Is it because of charge time, or fear of getting cells out of balance?

Seems to me that the only limitation would be either a power supply or a generator. I have charged 6 6s packs at the field and it took about 25 minutes using my PL8.

As far as cell balance between the two packs, I'd say that you would have them much closer after a parallel charge than after an individual charge on a two station charger.

I have seen balance issues in a single pack with parallel charging, different packs coming off the charger with different voltages, and issues with cells going bad.

I have been reminded over and over that every once in a while, if you parallel charge all the time, to charge individually to let the cells balance better.

Then I had an issue on my 700 where a bad cell caused an over current detected.

It was recommended to me to go for a dual charger.

Considering all of the above, I have decided to get a dual charger.....

I still parallel charge with my dual port charger. 6S goes on the left port, 3S goes on the right.

I usually charge my 6S packs 2 at a time, and my 3S 4 at a time.

You can also use the paraboards like Buddy RC sells. They are fused, adding a little bit of protection.

If you'd like to try a paraboard, I'll send you one free of charge, don't know how I ended up with 4 of them!

I got my DPL8 from Progressive RC, along with 4 of their Modular Boards.

I charge several packs at a time on each channel. After 3 or 4 cycles I charge them individualy to help keep the balance in line.

@Rockohaulic - I'd recommend you take a look at the bundles (MPA board, USB, etc.) as it's cheaper than purchasing individually.
