How to charge 2 2s battereis as a 4s

I took the adaptor I had and cut one of the wires, works great:

This is how I have it.

He he, that's the one. I kept getting the balance ports on the wrong battery side seemingly at random. It's important to have the green circled connections zip tied. =)

not tested this personally. http://www.hobbyking.com/hobbyking/s...onnector_.html but it looks like it wil do the trick

Here's a pic of the one I made for Hyperion packs. Different taps get wired differently.

Those work well. I have a few of them.

I found a great fix for this problem, no having to worry a big cluster and trying to remember how to hook things up. I found this at the hobbyshop and it was only $6, they have it for 3s batteries also. http://www.commonsenserc.com/product...oducts_id=2810 You hook the deans up to you charge leads, plug the adpator in to the balance port on the charger, and plug your battery balance plugs into the adaptor. Testing as we speak. It says its good to 15 amp.

Something does not look right with that.
You may be looking at a melt down !

Careful, 15 amps in 22 AWG might be considered an incendiary device!
I would think more like 3 amps for that size wire.

I do this setup to charge 10s bricks as two 5s packs, the balance wires get pretty warm on 3 amps.

Watch that setup closely.

Great site thanks JIM!!

Looks like if I get one of these

I can then use one of these to make the connection I need??

So your charge thinks it's charging 1 large 2s pack then?

I charge my 6S packs in series. Two 3S Hyperion packs are connected in series for one pack, and a 4S and a 2S ThunderPower pack are connected in series - both are charged through the power wires, not through the taps. The Hyperions need balancing every four or five charge cycles, but the TPs don't. I ran 16 sets of passes in a SAW boat with the 6S TP pack (4S+2S) and never balanced the cells - I didn't need to since the individual cells never drifted apart by more than 0.015 volt after all that extreme hammering. I would not recommend doing this with cheap cells, and I do monitor the charge closely, but it has been working well. Just pay attention (which you should do while charging any LiPo pack). BTW, this was recommended to me by a major LiPo pack builder. He was right.

monojeff:

No Sir. The adapter I made is a series adapter and charges the two packs pictured as a single 4200 mAh 4s pack. It will balance all four cells individually.

[monojeff]

Since my charger uses the taps not the wires to charge this should also work correct??
Wire them the same way as you have 2 2s connected together then to a 4s tap.

Is it faster or just makes it so you dont need to connect packs individually?
