How To: Make a Y Balancer Harness - Page 2 - RC-Monster Forums

[QUOTE=BrianG;157499]
The only way I'd parallel charge is 1) if the packs were always hooked in parallel when run and charged since they were new, or 2) balance offline (not hooked to a charger) in series first. Once all cells are balanced, then hook them in parallel to charge. Kind of a PITA IMO.

I want to build a saddle pack for a micro vehicle and due to space constraints I would like to solder the main wires together to make a 2s 2p
7.4 pack rather than making a paralell harness I would also like to balance via a 4s align plug to make it 2am in the morning proof can you advise which wires would need to be connected to the 4s balance tap and in which order packs are new Identical and balanced

Brian,
Happy birthday. I just want to say I always pay close attention to your posts as they have the most comprehensive knowledge I have seen yet. Always informative and willing to help. I gotta give it up to one of the forums most beneficial members.
That balancing bit was exactly what I was looking for.
Thanks

Is it safe to say that is also a good diagram for running a dual pack (y adapter) into a single pack lead ESC?

yes, that is it.

Alright BrianG I will get that picture taken tonight after i get out of class. Do you want the full sized immage because it will be very large. Thanks, Trever

**Lipo Configuration Question -** 11.14.2009, 01:40 AM

Brian,

I have some questions regarding your schematic under "Lipo Wiring" on your website. The example I'm using is a 5S2P lipo configuration. I want to know what is represented by the wiring where the positive and negative junctions of each pack seem to be bridged to another adjacent pack? In the attached photo it is circled in green if you can make it out lol.

I also noticed that there is only one balance tap for this entire configuration. It seems to be independent of the number of packs that are put in parallel provided that each pack has the same number of cells. I changed the cell parameters just to makes sure for myself. This seems to contradict your instructions on how to make a Y harness, where there are two balancing taps, one for each pack.

Hope you can clarify this for me.

Thanks!

Hey Brian, Thanks for all your help but it doesent work lol. Here is what i have. The pack had a kokam tap on it which i switched to a hyperion tap. I wired it like you said (+on the lone black wire than the -on the other black wire reads 3.7 -on the red wire reads 7.4 on a volt meter). I pluged it in to the hyperion balancing adapter that comes with the EOS610i and it doesent recognize anything is there. Just be aware i am charging through the main leads while using the tap for balancing. Also after i get thoes to work i need to work on getting a y-balance harnes to work so i can balance both as one! Thanks Man, Trever

P.S. I want to balance them tomorrow so if its possible for you to call i will send you my number in a PM. Thanks

Trever007 · 03.28.2008, 08:12 PM

Also what kind of resistance numbers should i be getting on a 2s lipo pack with my EOS610i? Thanks

This thread should be a sticky!!!

BrianG · 03.31.2008, 01:05 AM

@Trever007: If it doesn't work, there must be a wiring issue. I saw your PM, but have been away from the internet for the majority of the weekend. At any rate, it's hard to go over wiring over the phone. The best thing to do is take a large clear picture of your wiring. Make sure that the picture shows each individual wire. I can then Photoshop whatever is wrong and re-post it. That's probably the easiest/best way to do this without seeing it in person.

@Mahazael: Yes, that's a typical Y adaptor and can be used to charge two seperate packs as one AND run two seperate packs as one.

@E-Revonut: I suppose it could be, but how would it look if a mod stickied their own threads? As it is, there are already a few threads of mine stickied!

Bigger is better in this case, so yes. You might have to email the picture to me as there are image size/dimension guidelines in this forum...

Right on Brian, my thoughts exactly!

Glad I read the rest of this thread before this post, or I may have been mislead by its obvious sexual conatations!

BrianG · 03.31.2008, 10:25 AM

lol, only you (and other like-minded people) would derive some sexual innuendo out of that last statement...

Trever007 · 04.06.2008, 02:21 AM

i now have the taps out of the batteries working. I just needed to connect the red wire to a black one, black to a black, black to a red. Might make no sense but it works lol. Now i just need to make the Y-Harnes which i think will be difficult lol. We'll see. I might be sending you some pics of what i have! Thanks, Trever.

P.S. Do you have a starting point for making the Y-Harness using the colors of wires coming out of the Neu Pack and the voltages they should read?
