New lipos from Hobbyking!

[chroot]

I have iCharger 3010B can do 1s to 10s.

[Racer_X]

Thanks NeilP for the info

yea the 7s pack shows two balance plugs

Then I know my iCharger will work with those batteries.

[Arlo1]

Hmmmmm

Well yes, it and any of them will charge how ever many cells you give them, as long as the balance leads are connected in the correct order and the number is set in the software of the charger

Guys;

oh, and hyperion 14s charger guys.. it's your lucky day, finally HK sells 7S Lipo!

Price is a little higher, and shipping is only international right now. But if you want to jam the highest amount of amp hours into a limited space, these are exactly what you are looking for.

Nice find David, at first look it seems like a better battery option for us guys with the Hyperion 1420i that take full advantage of its ability to charge/balance upto 14s packs. I considered it for a while to upgrage from my 12s packs but a closer look at the battery's balance plugs shows it has two balance plugs rather than just one. It has two separte JST-XH plugs for 4s and 3s rather than just one 7s plug to go directly into the Hyperion.

I make a 20s4p pack of them to be 6% heavier with 9% greater volume but 16% more capacity. I should have gone with these for my next project not the nano techs I just ordered...And it is all your fault Netp that I just ordered more nano techs..all your fault because you did not tell us about them early enough ...all your fault nothing to do with me of course

lol, i'll tell my subconscious to dream about hobbyking's battery offerings more often.

Damnit, you guys are right That is a real bummer.
I searched a bit for a 4S + 3S adapter, and no such thing exists.
On the iCharger 1010b+, you can possibly pull the 7s charging off, but that's not too helpful is it.

I can't even find 7S JST balance leads on the web .. looks like this is even super uncommon in the RC world.

I think this is the 7S JST connector you're looking for:

Nice find keysersoze! Thanks!

Nice find keysersoze! Thanks!

No problem =)

This thread bummed me out a little since I just received some 6S 8AH batteries yesterday (ok, not that bummed, haha). I did a very quick and dirty comparison of the high capacity compact batteries to see if they were really that much more compact than my 6S 8AH:

Lipo Compact Comparison.jpg

(122.6 KiB) Downloaded 2 times

Conclusions - Ok, so the new compact batteries are mostly between 14% and 19"% more compact than my 6S8AH batteries, not to shabby. They also weigh less for their capacity, around 10-14%. Cost is about the same compared to the 8AH batteries, but the cheap 4S1P hardcase is still by far the most cost effective.

I've attached my excel sheet in case anyone wants to use it/modify it/ add to it

[quote="NeilP"]These new Zippys...the NIMh ones, what is the voltage regime for these...max/min voltage? charge current/characteristics , any "cliff' or a gentle discharge graph?

These are not NIMh, are they? They appear to be the same chemistry as the regular Zippys.

[neptronix]

Nice comparison, Keyser.

They're not NiMH batteries. not sure where that came from.

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?

[mrdavies]

im so interested in buying these (7s), however i dont think they will work with my icharger 106B ?
correct?

[ElectroSurf3r]

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.

[cwah]

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

[Racer_X]

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?

[cwah]

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

[motomech]

[Stating the obvious]-A pair of these and a pair of 6S 5800 mAh's could be configured into,

12S 5800 mAh
or
14S 5800 mAh
or
13S 11600 mAh
neet!

Also, if anybody cares, Hobbyking added a Zippy[regular] 6S 5000 "long" battery.

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.

Jason.

[IBScootn]

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

[Diamondback]

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

Jason.

[FastDemise]

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:

But ebay does have 8-pin 7s jst-xh cables: (here's an example)
