Charging 2S+ with Accucel 6

[BigHonu]

Got my Accucel 6 in and have had great results charging single 18650's and 26650's.

Now I want to try cells in 2S+.

I understand that I need some wired adapters/harnesses to plug into my charger.

I understand that the adapter/harness will have to be modified to be able to charge bare cells.

I understand that the adapter/harness will have one more wire than the amount of batteries I want to charge, i.e. to charge 4S, there will be 5 wires consisting of one positive lead, one negative lead, and 3 balancing leads.

I understand that the balancing leads go between the batteries in series, and the + and - leads go to their respective ends of the battery chain.

What I am unsure of and looking for guidance on are:
1). Where do I get those adapters?
2). Can I get the 6S harness and still charge 2s? (leaving the remaining balancing leads safely isolated and tucked out of the way?
3). Do I still need to hookup the primary output + and - leads to the series pack as well?
4). I have read that I should stay around .7C for charging. Since I'm doing two 2600mAh batteries in series, would I still use a 1.8A setting on my charger?


Thanks for any input!

I'm not absolutely sure because I don't have an Accucell-6 charger, but I think they use JST XH connectors that you can get from Digikey.

Charger? http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=7028

7 lead JST XH connector: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=455-2269-ND

If this is correct, you will also need the female pins that go in the connectors. If you scroll down to the bottom of the DigiKey page there are associated products, the female pins that go in the connector. Also, there are the mating sockets, at the bottom of the digikey page, if you need those.

Hope this helps.

Russel,

Thanks for the information!

Yes that is the charger.

I was hoping for a pre-assembled connector as I am horrible with any crimping or soldering.

You could always order an adapter for a few bucks. The cord that goes between the adapter and the charger is the same at both ends I think. If so, you could cut it in the middle and extend the wires to your battery taps. You would still need to solder the battey pack tap leads, but at least you wouldn't have to deal with the itty bitty pins.

Thanks! That looks about perfect.

Does the balancing go between the pos and neg contact of two batteries?
