44.4v 16ah

[Ossielocal]

Hi guys,bit of a noob when it's comes to Serial/Parallel Connection .At the moment i have a ping 48v 10ah battery i'm looking at getting 4 of those ZIPPY Flightmax 8000mAh 6S1P 30C would be worth getting and would i get longer ride out of these batteries ! How would i wire them up to make it 44.4 16ah . Cheers

[rojitor]

you can use this image for reference,it is pretty much parallel 4 packs and then make one series, nevertheless i think buying a harness is your best choice until you know what you are doing. icecube57 makes good wires, this is his site http://lipoconnectsolutions.onlinewebshop.net/ and this is the thread http://endless-sphere.com/forums/viewtopic.php?f=31&t=30367

That diagram shows exactly how I do it, except I can't charge at 44v with my 22v chargers. So I have to break the series connection to charge as two pairs instead of all four at once. Icecubes harnesses solve the problem nicely, as explained in the threads linked above.

Since the ping battery charges to 60v max, and the lipo 12s charges to 50v max, you can't connect the two. You have to ride one, then disconnect and connect the other to finish the ride.

Gday dogman , you where saying You have to ride one, then disconnect and connect the other to finish the ride. Just wondering why i can't connect all the batteries to make it 44.4v 16ah ! Getting a little confused .

[dogman]

Edit, maybe I just misunderstood. You can connect the RC lipos and ride them as one 44v pack. I meant you can't connect the ping to the RC lipo. So you ride the ping till it's discharged, then ride the RC lipo till it's discharged. You can't paralell connect the ping to the lipo.

Because one charges to 50v, and the other to 60v. If you plug the ping into the RC lipo, the pingwill start overcharging the RC lipo.

You could wait till the ping is at 50v, then plug in the RC lipo, but that would be equally useless. Idealy, you'd stop riding the ping at about 50v. Bms gonna trip at around 48v.

Then there is the issue of do you or don't you need diodes to protect the ping bms. You don't of course, if you don't paralell them.

In general, you want to have the same cell number and same chemistry to paralell them. But some combinations can work. 14s RC lipo is pretty close to the 48v Pings voltage. If you did connect the 14s RC lipo that charges to 59v to the ping, you would want to stop at about 50v, the 48v lvc on the ping would be overdischarging the lipo.

[Ossielocal]

lol ,i see where your coming from now ..I'm just replacing the ping too the rc lipos ..going to sell the ping battery . So i am just going to use the lipos . Found some pics of wire harness i would want some think like that right ?

[dogman]

Yes, that sort of thing would work great for you. Buy or copy the Icecube 57 design. (see his thread in for sale new) That one you show has all andersons, but it would be easier to make it with andersons on the one end, but bullets on the ends that connect to the lipos. PITA to convert the lipo to andersons.

Thats like beta 0.0 when i didnt know any better lol

Your 10ah ping charges to close to 60v while the 12s lipo will charge to a ~50v. To compare riding time, you need to know the watt hours of each pack. Ping is 528wh and zippy is 710wh, so you should get about 30% more range with the zippy. To wire, simply stack 2x2.wire bottom 2 together black to red, top 2 together black to red. Then parallel the open ends on each side.

Just a pitch for IC57's harnasses. They work great and are seriously professional in quality. Worth the cost every time!

That's what I do. Since the majority of my rides are local and I don't need much range, I use just one 12S/5Ah pack, which is 2) 6S/5Ah bricks taped together and wired in series. Why carry way more battery than you need, especially if that space can be used for groceries ?
If I think I might need more range, I parallel 2) of the 12S/5Ah packs to get 12S/10Ah using these;

Which are the standard HK parallel adapters[left]which I have replaced the "common" leg with 12Ga.

So each "leg" is ;

12S/5Ah 14Ga.
....................... 12S/10Ah 12Ga. controller[s]
12S/5Ah 14Ga.

That's as much as can be wired up at one time, but a really long ride, I carry 2) more 12S/5Ah packs which can be swapped out in a minute or so.
I like the "building block" approach, but I don't do daily long commutes on my bike.
Also, the 50V[hot] packs don't tax the 14Ga. wire of the HK adapter.

O.P. I understand your attraction to the 8Ah packs, it seems a simple and elegant approach, but you pay dearly for those extra 3000mAh's. I'm in the process of chaNging over from Zippy 15C's to Turnigy 20C's and I'm very impressed with the Turnigys. I'm only seeing a 1V sag pulling over 1000 Watts on a fresh 12S/5Ah pack, compared to 2V's with the Zippy 15C's.
And at $44 per 6S/5Ah brick, you could have 20Ah's of 12S for less than you will spend for 16Ah's of Zippy 8Ah's.

[Ossielocal]

Gday Motomech, i was going to go 5000mah batteries but i would still need 6 of them and it would of come to the same price i like to go for a 50k rides on the weekends along the beachfront ..Going 4x 8000mah batteries just means less wires less mess too . Is 12awg wire good for my setup being the batteries 8000mah ? I will be buying a Hyperion EOS 1420i NET3-AD Balancing DC Charger so i don't have to take the batteries out of the box all the time .I've attach a couple of pics of the setup i want to do .

I've seen in Hobby king the 6s 15C zippy, they do seem quite good on the specs. They top at 163wh/kg, which is much higher than the 20C Turningy. Zippy 15C are a little bit more expensive, but they remain really cheap and you won't find any battery at this price at 162wh/kg! If you have too much sag, just double your pack and increase the AH. The sag will be lower and you'll have a high capacity pack with one of the lowest weight possible.

Well, i never weighed the individual bricks, but I just weighted one of each of the Turnigy 20C and the Zippy 15C 12S/5Ah packs and I got;
Zippys-22.55 Oz[my scale only does oz.s]
Turnigys-24.8 Oz.
So there is a substanial weight difference of 1 1/4 Oz.s per brick, but not the 2 Oz.s per brick that the HK spec.s would indicate.
So, a sm. pack of Turnigy 20C would weigh a 1/3 of a pound more than the same 12S/5Ah of Zippy 15C. Given that my Ebike weighs 56 lb.s and my batteries are well placed in the frame, that difference is inconsequential. And if I felt I had to add more 15C just to mitigate voltage sag[in reality, 2V sag is nothing, especially for someone who came from LiCoMg and was used to seeing sag in the 3 to 5 V range!], how does that save weight?
But we are nit-picking. But there is one factor that I.M.O., makes the Turnigy to one to go with and that is US warehouse availability. We here in the States greatly prefer to get our batteries from the US warehouse and for the last 6 months or so, the 15C Zippy 6S/5Ah's have been real spotty, where the Turnigy's have been steadily available.
Since I'm using both, time will tell, but my gut feeling is the Turnigy is the better battery for the money.

Gday Motomech, i was going to go 5000mah batteries but i would still need 6 of them and it would of come to the same price...

I see you are from Down Under, well for us there is a real price difference because the Turnigys are available from the US warehouse, whereas the Zippys are not.

Is 12awg wire good for my setup being the batteries 8000mah ?

[/quote]
I think so. When I originaly went with 12S/10Ah, I was 14Ga. all the way to the Cycle Analyst shunt and when removing the batteries, I noticed the wires were warm. Since going to 12 Ga., I haven't noticed that at all.

Are you talking about these Turningy pack?
http://www.hobbyking.com/hobbyking/stor ... ouse_.html

If so, you wouldn't find anything cheaper for the money. I thing these are the best bang for the buck in term of lipo lol.


And I suppose it's these Zippy 6s?
http://www.hobbyking.com/hobbyking/stor ... oduct=7639

At 22.55Oz/pack, it's lighter than what is advertised. So maybe not the right pack

No, I'm refering to these;

Note that they are in stock in the US warehouse.

And yes, I was comparing them to these'

Thanks Momotech. The same turningy pack on the EU warehouse is 65$. Way more expensive I don't know why lol. Doesn't make sense for me to get them.

Hey guys ,One more question whats a good fuse to use with this setup ?

[motomech]

I use one of these;

That's the beauty of 44.4V, you can use standard off-the-shelf HD auto. stuff.

[wesnewell]

That's what I use too except from Walmart $1.28 ea. But i use a 40A fuse in it with 24s. A short might blow the fuse and fuse holder up, But it's so cheap I don't care.. It has 12awg wire and the rest of my wiring is 10awg with 60A connectors.

[icecube57]

I melted Maxi fuses with these type of holder under sustained load. To the point I couldnt get it open. When I finally got it open i couldnt pull the fuse.. out. I threw it away eventually.

[Ossielocal]

Howdy fellas , finely getting my shit together ..lol got the lipos all hook up was a little scared doing it for the first time just like i had sex for the first time ..lol just need to do the balance wires for charging and waiting on the power supply ,for the power supply i brought my self a HK Turnigy 1080W 220~240V Power Supply (13.8V~18V - 60amp) .

[Ossielocal]

Hi guys ,still learning stuff i want to charge 2 lipos at once just to test the charger out how would i go at connecting 2x6s 8000mah lipos ..which harness ? Hyperion EOS 1420i NET3 14s Balance Charger..

[wesnewell]

http://www.youtube.com/watch?v=7I76y8ei ... re=related
Just plug the black of one into the red of the other to make a 12s pack, You will have to split the connector on one pack to do this.
