I have a BC6-10 that I have been using to charge 3 cell packs, nicad's and the metal hydroxide packs. I love it and have had no issues with it.
I jumping up to the big birds now by coverting my EVO 50 to e-power. I'll be using (2) 5-cells packs in series for power. Starting off, I'll just be using the 2 packs. I read on one of the forums something about paralelle charging. I assume this is both packs at once with through a paralelle connector. Can the BC6-10 do this and if so how? Don't want to kill the charger or the packs!

Yes, you can parallel charge the batteries on the BC6-10. Using a Paraboard, you would plug the balance tap from the Paraboard into the 6S socket on the Bantam balance board you have now. The BC6-10 can charge up to 10 amps with a 200 watt max output. Contact me if you have any questions. We also have the paraboards in stock and can show you how to use them.

Excellent! Now, are you saying I will be charging thur the balancing tap, or actually charging thur a deans (all my stuff is deans) paralelle "y" connector?
I assume I could do my 3 cell packs the same way.
I have 4000 ma 5 cell packs. Charging individually, I'd charge at 4 amps. Doing 2 packs, would I jump that up to 8 amps?
Like wise, I charge my 3 cell packs at 2.2 amps, would that go to 4.4?

You need what is called a Paraboard. What balance taps do your batteries have?

[lrogers]

I have a paraboard coming, the packs have the "align" style taps.

OK, then you are ok.

Forgive me if this has been covered already but I did look.

I'm using a BC6-10 and a EAC144 balance board to charge 2 x 3S lipo's. When I first got it I connected two recently discharged cells and balance charged them simultaneously. All 6 cells balanced normally.

Coming to charge/balance two more packs, I have just noticed it is not now balancing all 6 cells, it leaves the pack with the lower voltage per cell and charges/balances the pack with the higher voltage to 4.2volts. It then continues to charge the lower 3 cells at about 100mA which takes for ever.
Can I assume that the Bantam BC6-10 will only balance 6 cells provided the individual cell voltage is within certain parameters?

You are correct. By connecting 2 3S packs together, the charger see's a 6S pack. If the cell voltages are off, then the charger has to balance the pack. If the cells are very far off, the first set of 3 that hit 4.2V, the charger will reduce the current to .1-.2 amps and it will take forever to balance the pack.

When charging in series, all the cells between the packs must be very close in voltage. I would recommend parallel charging over series charging for this very reason.

That's great, thanks for the confirmation and prompt reply
