Custom Lipo Series Parallel Harnesses & More!

[icecube57]

OK I have one power supply ready to go with a connector of your choice on the output. This on is non Isolate.. There is an automatic fan mod and the power supply automatically comes on when activated. This unit has a voltage of 11.9. The back panel where the connections are made is filled/covered with hotmelt to prevent shorts across the outputs. Its rated for 12v 57A =700w. You could run two IChargers off this or whatever you can think of. The going price on this is 45 plus shipping. The Isolated unit is 60 plus shipping. Both units combined for 24v is 90 Plus shipping.

Hi mate,

Are you able to get these in 24V? I thinking of running a Hyperion 1420i off of one. Great price too by the way.

Cheers, Tom.

Two of these in series will give 24+v to run a hyperion at full power.

Hi Ice
I need a wire for the following battery pack:
1) 28S2P 8x - http://www.hobbyking.com/hobbyking/stor ... duct=21384
2) The following charger 14S: http://www.ebay.co.uk/itm/300684982361? ... 1439.l2649
3) Motor Crystalite 5403
4) Lyen 24Fet FreeWay controller

So i need harness for all this staff... Maybe including balance leads.
Please PM me for the details.
I`m in Russia...

Hi mare I have just purchased a CroMotor and a 24 FET 4115 MOSFET 84-132V Freeway Speed LYEN Edition Controller and 12 packs of ZIPPY Flightmax 8000mAh 6S1P 30C, 6 Packs in series 2 in parallel for a total of 36s2p 16Ah 151.2V, can you hook me up? cheers.

^There's a more important customer post right above mine,


but, I just wanted to express some concern if your two power supplies in series are not isolated in the right. Not sure if you knew that could be a problem if things go wrong, but you might want to put together a case so that if they do fault and run hot ac on the case, then you can't easily touch it. [though in general I've seen your posts around here being very knowledgeable, i just wanted to make sure since I read the post above and don't have any background as to how you make them ] And/or, some people put a neon light wired between the two cases and if that lights up you know there's an AC current flowing and shit got real.

[icecube57]

Thanks for your concern. The DC ground is floated on one. The AC ground hasnt been clipped. They both retain AC ground. Ive touched both of them together. Ive touched them both with my hands... as a matter of fact they are taped together right now and the cases arent insulated and they arent faulting out. Im not selling these or anymore and keeping them for personal use. They are selling on ebay for lower than what I would like sell them for... even though ive gone the extra mile and these are adjustable and the fan mod has been applied for quieter start up operation.


Its funny I was gonna make an instructable on how to make them when I was going to sell them cause there isnt any truely clear info in one spot then i figure it would prob need to be proprietary info but since im not selling them Ill see if i can scoop up two more and atleast make a picture video on the dc ground isolation and fan mod and what pins to short out. As a matter of fact here are the links I used.

I hope you are going to under charge you packs cause it could potentially be to hot off the charger at full charge and could cause the mosfets to fail but im sure you already talked it over in a thread with Lyen. Ill pm you with a rate.

[Olly3012]

Yeh all good cheers ay.

[RallySTX]

Well I'm sorry you decided stop, as I was looking to get a set from ya in a month or so. I'm in the process of paying for a van now, but need a setup like that for my 6S packs when I get them.

Apparently I was false advertising... you cant connect these directly to packs but they still will power a i charger or hyperion to its full potential. Plus there are vendors on ebay selling a nice combo cheaper... not as many mids but its a nice package .... Remember my time is valuable and if my projected price does not fall inline with market price or demand i dont have the money to venture in it to deeply. I threw it out there to see if there was a bite... not much going on.. time to shelve it keep it for future use until someone in the future wants... I originall was going to buy 8 sets but im glad I tested the water otherwise i would have been sitting on some power supplies.

In other news i finsihed up a 5s3p harness.

[icecube57]

All things consider maybe I was pricing the supplies a little high I could probably do 60 plus shipping for a set. The sister model without the pop was throwing me for loops because it was isolated before i put the top cover on but afterwards i had continuity again. I know for a fact that when i buy them off of ebay i must request I get two of the AB model instead of the non adjustable bastard model. I just bough 100 pcs of fiberboard washers. Considering the power supplies are 28 for a pair and the resistors are less than a buck all and all 35 goes into two and since i know how to do it now it should take far less time to do it now that i thorougly know what to do.


Anways These two power supplies i have modded someone can pick them up at the new price of 60 plus priority mail shipping. I have to get my money correct and stacked up so i can buy a motorcycle... time to cash in on these side projects that got my bank stash side tracked. I wont have a ebike until like fall maybe these will just be collecting dust in the mean time.

[RallySTX]

All I'm lookin for is a way to power my i-charger. I need another one of those as well as batteries, boxes, frame bags, and hardware. Today I'm gonna give what I hope is my last full payment for the van. Next month I shouldn't be so broke. What kind of bike er motorcycle, are you lookin at?
Brian L.

[icecube57]

Still have these two supplies i need to get rid of. Make a reasonable offer and its yours.

[icecube57]

New additions to the family 4s 4p inline fuse no connectors on pack side no precharge.

[RallySTX]

Nice lookin work as usual. I'll let you know next month if I have something to offer you for the supplies.
Gotta tagle with a court battle now, pesky creditors.

I just did chapter 7 here to stop garnishment.. money hasnt been right for 5 years. Making 1/3 of what i was making then.

Anyways I got a jacked up question. HAS ANYONE HAD PROBLEMS WITH THEIR PRECHARGE resistor. Im thinking the fine wire on the resistor is a weak link and I thought i was putting enough strain relief on the wire with the heat shrink on it so that it doesnt wiggle... I only have 1 incident out of like 20-25 where it has broken off in the field.... Trust me when Im making the harnesses its a PITA. If you guys have any problems im willing to look at repairing or redesign the way I do stuff. Id rather have it known and get slammed than send continue to send out garbage.

[Alan B]

I don't have one of your precharge resistors so can't comment on those, but when I did one was concerned about the leads failing, so I set it up such that the resistor's wire leads didn't flex. I attached stranded wires to the resistor's leads, and then attached those to the resistor body with heatshrink. So the resistor leads curved around and then were clamped to the resistor body. So there is no flexing of those resistor leads, all the flexing is in the stranded wire which can take it. Resistor leads are not designed for any flexing or they will eventually break.

[fractal]

my pre charge resistor works great on the 24s 3p harness you made for me. no sparks!!!

I actually had a problem with my prewire resister. In working with an 18 fet controller from Lyen who he has now for repairs on hooking it up it blew the fuse in the harness (brand new controller)
and after replacing that fuse for some reason the voltage is never right. So I don't know if there's more resistance where the fuse is or what. I took it apart cleaned off residue from the previous
blown fuse - took apart everything to check connections looked good. Ended up dismantling the resister and it looked like I "may" have had a bad connection where it enters the ceramic.

So lately I have just been running without the fuse/resister. Figure if I mess up my 12 fet I have a couple spares ready to go.

I still don't think this is anything you did wrong and just a combination of something that happened to me and I only posted because you specifically asked.

I have never gotten this 18 fet controller to work from Lyen and he's looking at it once again. The behavior on the controller is when I hook it up to a battery it's just like connecting the
positive to negative on a battery.. 1st time It vaporized my andersons.. 2nd time after he fixed it it blew the fuse.

[icecube57]

Atleast there was a fuse... and it did come in handy cause it sounds like it could be much worse.. Sounds like something else but its odd for a mosfet to be shorted(which is what it sounds like or the controller is having a problem starting up with the precharge. Is your ignition line hooked up to the positive or switched separately. Ask lyen if this interfers with the smps that hee uses on his controllers now. I just started soldering the precharges a different way you prob had an earlier version where i was just really over complicating it lol . I doubt it was polarity problem cause ur using it on another controller. Let me know what I can do to make it right. I remember castle creation controllers will blow with a precharge. The precharge is sized correctly for the voltage.

Did the fuse explode or something. I chose the AGU fuses so they wouldnt charr do something damaging. I have a really bad memory and since I delete most of my pics you have to remind me which fuse holder you have.


Alan B thanks for the insight I may start doing it like you suggest. I did have strain relief in mind when is started using the precharge resistors. I used 2-3 layers of heat shrink to prevent flex. but i may start doing the fold over method so that it doesnt bend or flex at all. What im doing now is stripping 2-3mm wire then inserting the leads in to the stands and insulation and fluxing and soldering it and heat shrinking. I know the leads will eventually break.. i cursed at my several first attempts. and wasted 3-4 on my first few attempts.

1st time when it vaporized the andersons- did the fuse not blow, or was that before you had the fuse? eitherway, the main reason why a thing acts like a short circuit, is because there's a short circuit (:P. A least, in my experience). And I guess I'm surprised the andersons blew before whatever component inside the controller was shorting (though I've never used andersons for high power and don't know if they're as resilient as 4mm bullets).

[ohzee]

ba-bump

[Kin]

Oh! Ohzee, sorry, I'm no expert. I was just trying to troubleshoot to understand a bit. Very confusing behavior there. Lyen is a better guy than most to be dealing with, and I am surprised you found it a bit haphazard. Hard to see the full picture without actually having your equipment on hand. There's a possibility what is going wrong is caused by your motor, and that is why it would develop the problems again even after Lyen repaired it once.

Uhhhh, to icecube, thread bump!
