Home made Parallel "Y" Connector

I'm using three 3S batts for my scaler, but space is becoming an issue.

Instead of making a Y connector with all of the batteries going to one plug, I want to solder the deans in-line with each other to save space. I will hook all + together and all - together to keep them parallel.

Will this type of setup drain one pack faster than the others?

So you want to run the 3 packs "+" to one deans pin and 3 packs "-" to the other deans plug?
That is a parallel circuit, the packs should drain fairly evenly PROVIDED they have the same specs (mah & "C").

Why not just either get a bigger mah pack, or swap them out (as 3S packs) a little more often???


Ummmm...sorta stupid question, how are you going to charge them back up?? The charger will see a "9S" pack, that is a lot. You have also limited how to balance them.

Just something to consider.:roll:

I just want solder the male deans plugs in line, + to + and - to - all running to the same dean plug at the esc end. The batts will still have their original female plugs soldered on to them. (I can still unplug and charge them independently).
Kind of like a fuel rail for a fuel injected car.

Because of the amount of space I have, I can't get 1 large pack in the truck. 3 small packs will let me up the mah, and not have to change packs in the field. 3 1300mah 3s packs will give me 3900mah! not bad.

I made a 2p adapter like this.
I put a pair of male plugs next to each other with a drop of glue between the housings to keep them aligned. then put a female plug opposite the pair so that the + and - terminals were all as close as possible. I soldered the matching terminals together, I think I wound up needing a piece of 12G wire because the terminals wound up just a bit too far apart to use only solder.
once the adapter had cooled I had a single solid adapter that connects 2 packs in parallel to 1 esc. I wrapped the exposed plug ends with masking tape and used a liberal amount of "liquid electrical tape" in the middle to seal and insulate the assembly.

Thanks Chris! That's exactly what I was going for. I just wanted to make sure on the draw between the packs.
I appreciate the phone call too.

BTW:
Your avatar is mesmerizing!

Interesting. Might be difficult with 3 batteries.... makin my brain hurt just thinkin about it....

you could do it like this, assuming you use heavier wire than the 26g I used for the mock-up and use the proper polarity of connectors.

Creative, but won't work for my setup because I have the power routed to the rear so I can unplug it while I'm in the field.
Good idea though
