Same here! Mine are currently held up at customs. Good thing I only ordered 2. So I'm now thinking of puchasing some 7s and series these with the 6s.
So is this do-able? Can anyone foresee any problem in mixing 6s Turnigys with 7s Zippys in series, (total 13s)?
The Turnigys I have coming are 5000mah 20c. I would think I should try to keep capacity the same for the Zippys.
What influence would the different C rate of the Zippys have?

You won't be able to balance-charge all 7 cells on that iCharger, it's only good for 6. You could still charge the 7th cell afterward as a 1s with reasonable accuracy using the cycle function, but that could quickly become a pain, depending how your pack is arranged.

I don't understand. Why do they have 2 balancers cable on the lipo?

7s balance adapters are not common so alot of people would not buy this battery because it is not compatible with there charging system.
with a 4s and 3s then most 10s and 14s chargers will work.
You got it?

Ok thanks. I'm considering these battery because of the high wh/kg it achieve. Maybe will get them later and I better have the right charger :lol:

sorry to dig up an old thread, but i have question about charging those 7s batteries.
i have a Hyperion EOS 0720i Super Duo 3 Charger.
can anyone who has this charger (or one of the other 14S capable chargers)
please explain how i would charge this pack ?
the charger has the balance connector boards that go from 2S - 7S in single plugs.
would i just plug in both the 3s and 4s into the one balance board ?
or would one have to go into each ch on the charger ?
only had the charger a short while, and still coming to grips with it.

I would dump the two balance connectors and just use a single 7s connector

I searched the web and HK site and didn't see any 7S connectors.
Or even an adaptor for the 7S charge lead.

If you have a parallel charging board you could hook up 2 of those 7s batteries with the 5 pin connectors in parallel then on a seperate board the 4 pin connectors. That would work for people with the Hyperion chargers that are 2 seperate 7s chargers. What you think?

No! If you did that you'd be getting sparks! shock:
Because you'd be putting cells 1 thru3 in parallel with cells 4 thru 6
(but they are already internally wired in series).
I believe you need to use put the 4s on 1 balance board attached to Channel A,
then put the remaining 3s on another (separate) balance board attached to Channel B.

Diamondback,
Check out this link for a 4s + 3s to 7s jst-xh adapter:
http://www.allerc.com/hyperion-7s-split-pack-adapter-g3-pack-to-jst-xh-charger-p-5212.html
But ebay does have 8-pin 7s jst-xh cables: (here's an example)

thanks for the links.
i think i will buy a 2 of those adaptor cables.
at the moment i don't have any 7S packs in my collection, but that's only a matter of time.
when my current lifepo4 pack goes to battery heaven, ill go lipo and run 2x7S packs in series
for 14S. then split them to charge. probably buy 4x 7S packs so i have a decent range.
use 2 at a time. when one lot is flat, ill swap them over for the fresh pair.
thanks again.
Jason.

Hmm...looks like I posted that adapter link too quickly. It has two 4s connectors, not 4s+3s, so maybe that isn't the right adapter. I quickly looked at the 4s+3s tags and didn't look at the actually connectors. My bad.

I suppose you could use a 6s charger/balancer with the balance cable hooked up to one of those JST plugs and have an Astroflight blinky balancer hooked up to the other? For only $35, a person with a 6s charger could move up to 7s or more without buying a new charger.

No it looks right... The picture (on the right) actually shows a 4s + 3s connectors "Y" into a single 7s connector.
Good find IBScootn.

Another consideration you guys have to think about is that they come with 5.5mm bullets most charge adapters are made with 4mm bullets. This is the principle holdup for me, since I am just learning how to solder and I would have to remove the 5.5mm bullets and replace with 4mm bullets.
Those charge adapters are not good for discharge ( they are rated at 20-30A maximum, but will probably induce plenty of resistance at the upper end of their handling ). So you'll have to make your own harnesses anyway.
Better start learning to solder if you wanna go the lipo way :] or hit up icecube57 if he's still making harnesses and you've got a little cash to blow.

i would only want the adaptors for charging.
no way would i try to draw any significant current through those small balance wires.
as as for the bullet sizes, those are not an issue either.
i would be changing the connectors on the batteries anyways.

if you give me enough quantity, i may be able to get you any product you need regarding for 7s..
for now i only have 7s balancing harness 4 /5/ 6 to 1 if im not mistaken...

Huh? you never charge or discharge through your balance wires... i think you got some things confused.
changing the connectors on your packs are a pain in the ass, so it's best to make a parallel/series harness based on whatever connectors your lipos come with that will be used during charging and discharging.
You do not want to have to plug/unplug a bunch of wires every time you charge. Trust me when i say that gets old very fast. It also increases the possibility of plugging in something wrong and.. kapow!

i have had more than one charger in my time that ONLY used the balance wires to charge.
and did not have main battery output connections on them. i still have one in the cupboard now.
it's a 2A mains lipo charger for 2S and 3S packs. i think it came with my RC hovercraft.
as for changing the battery connections, i have to do that for most all of the lipo's that i buy.
im using XT60 type connections on almost every RC vehicle i have. so changing 2 or 4 more really is no big deal.
as for the series harness, i already have an XT60 type series harness made up. so all i would need is to plug the one
series harness into each battery, then the other end of the series harness into the controller on the bike.
i would not be running a 14S1P setup, only the 14S and that will all but eliminate the possibility for incorrect connections.
i would leave the controller end of the harness alone, i would only have 2 plugs to contend with (one for each battery)
and that's only one more than i have now. sounds idiot proof really. and when charging happens, ill have to deal with the balance connectors.
right now, i just have to plug the ping into the charger. no balance wires as the BMS is built in.
so for charging, ill have 4 to deal connections to deal with. once again, no big deal for me.
