I'm looking for a new charger. Just wondering if anyone has an opinion on this one from DN Power. I like that it charges the cells individually, no need for an external balancer. There is a digital readout for each cell.

DN Power G2

I'll be using it for small batteries, 800 to 1300 mah. Comments, recommendations?

Thanks!

I've been using mine for over a year now and it has performed flawlessly.

Good charger for the money IMO.

I have the CommonSense RC version of this charger. It hasn't let me down yet. The only thing I don't like about it is the charger doesn't show how many mAhs it's putting back into the pack.

One of the things to consider is if this charger will meet your needs in a year from now.

One of the most well featured chargers is the e-Station BC-6. Does all chemistries including 3 lithium types, nicad, nimh, and lead acid. Up to 6S packs, 5 amp charge rate and has the balancer built in. Also has a built in AC power supply as well. Use it at home or at the field.

Lipostuff.com also carries the BC-6 charger.

Guys,

We sell quite a few of the DN Power chargers and don't hear any complaints. I will second Evan's advice though, be sure that you get something that will work for you as your progress through the hobby. Here is a link to the BC-6 on our site, they will be in stock this afternoon.

When I bought my BC-6, I was able to sell my Triton, Cellpro, and my Power supply. I actually made money by switching!

That is true! Robert bought the BC-6 from me at regular pricing although he was a dealer, but didn't carry the e-Station line. Liked the charger so much, he is now carrying the charger line. Doesn't get any better than that. All good stuff.

Good points about looking to the future! But can we say that in a year from now we aren't all going to flying A123 packs?

I did look at the BC-6 and it looks very nice. One thing that I liked about the DN power charger is that it charges the individual cells. The BC-6 requires the main power connector as well as the balance connector. At first glance, it sounded like the BC-6 was using the main power connector for the charge current, then using the balance connector to either suppliment the lower voltage cells, or bleed of voltage from the higher cells. Where as the DN power charger appears to be running an individual charge out to each cell. As I thought about it more, there's no reason the DN couldn't be doing the same thing, via the balance connector. The difference being the DN doesn't pump a ton of current and can likely get away with using the smaller gauge wires on the balance connector. I'm not sure how either charger actually functions. Evan do you know?

I've also been looking at the FMA Cellpro. It looks to be in the a bit better than the DN power, but its still limited to the medium to small batteries. Plus it needs a DC source unlike the BC-6. But like the DN power it also charges indivual cells.

The DN is a parallel charger, meaning each cell is charged individually. There is no advantage to this, if there was, every one would have made their chargers this way.

The BC-6 built in balancer, bleeds the high cells at a rate of 300ma.

You'll find the BC-6 to be easy to use yet very flexible.

The BC-6 charges A123 packs in addition to LiPo, LiIon, NiMh, NiCd, and Pb batteries and has the integrated power supply. It charges as you said, through the main charge leads and bleeds off through the balance taps. It charges LiPo packs of up to 6S at up to 5A of current.

The DN Power charger charges individual cells as you described, but is limited to 2A of current, and a maximum of 4 cells.

The Cellpro is limited to 4A of current on the newer models and 4 cells. I know that at one point there was some confusion as to how the actual charge was applied on this one, but I don't remember what the outcome was.

Neither of these have an integrated power supply.

I vote for the cellpro, it charges/balances the cells rather than charge through the main lead and discharge balances through the balance lead. The cellpro is also a 4amp versos the dn which is only 2amp. The cellpro has way more options as than the dn. Read up on it and you will see why.

Robert, Evan,
Thanks so much for the replies, much appreciated. I wasn't aware the BC-6 worked with A123 batteries, good to know.

Heliman450,
I found the CellPro info after I started this thread, and have been impressed with its features. If it were between the CellPro and the DN, I'd take the CellPro. But now Robert and Evan have me thinking about the future. With the CellPro I still need a 12v power supply and haven't exactly figured out what to do there. I was thinking of getting gel cell or a DC power supply. Either way its one step closer to the BC-6 in price.

Then there's the issue of balance connectors, something I haven't quite sorted out. If you use all FMA batteries, no problem. If you have a mix and none of them are FMA, then you need a few adapters, which adds a bit more to the cost. I was also surprised to see the FMA adapters for the various batteries are not simply a cord with correct plugs. But instead its a cord connected to a PCB board, with plug on it.

I'm not sure what the adapter story is for BC-6, maybe its the same. I have one eFlight battery and was going to add a Thunder Power.

Bantam also uses an adapter board for the balancing, but there is a difference between Bantams boards and FMA's.

All the Bantams boards will do 2S through 6S. The FMA boards, depending on which board, some will only do up to 3S.

One of the adapter boards of your choice is included with the BC-6 from my web site. Then you can buy any additional ones that you like.

Bantam has 4 boards, Align, Kokam, PQ, and TP. Between these 4, you cover 99% of the batteries out there. What is not supported is the old Tanic packs and the FMA batteries.

I am sure you will make the right choice, both chargers are excellent chargers. Just remember down you road you might even get a powersupply because you might want to hook up multiple chargers.
I have the radioshack 25amp, I am able to use my three chargers on this powersupply no problem.
