charging 3 2s lipos wired parallel

[Badcopyinc]

I searched for a while on this subject. and all i turn up is wiring diagrams.

I took two 3s 500mah lipos apart and made three 2s lipos and want to wire them all together parallel.

I wired each set with a 2s balance plug because i have a bad habit of never charging without it pluged in on my b6 charger.

My only concern is how to charge these because i would like to solder all three together in parallel to a deans connector. Im just not sure if it will charge just two cells through balance while having the deans plugged in?

am i forced to keep the main leads separated and make a y harness for when im using them in my crawler?

So after extensive research I realize I'm stuck making a harness and charging separately .. Sorry for wasting anyone's time if you read this.

If you have the main leads permanently soldered into parallel it's no sweat to also have the balance leads in parallel.
You'll end up with a 2S3P battery pack.

All cells will thus get balanced correctly!

Thank you I was thinking I was stuck waiting for my connectors to come in the mail before I got to drive this thing I did do a search this morning and found this it includes a diagram

Can you post some detailed pic's of your wiring to help anyone else who's looking for this info? Thanks"thumbsup"

let me start off by saying i had to pull all my foil tape off to get these pics and any electrical tape still on is just solder underneath.

this pic is of the original zippy 3cell pcb i de-soldered the middle cell and ran a jumper to replace the missing cell

I left the original cells balance connectors in tact and moved the white balance wire to the jumper plate.

you can also see the balance wires going down to the removed cells where they where soldered in parallel with those balance wires

This one is the removed cells and the wiriing is exactly the same concept positive and negative with a jumper in between both cells going from one cells negative to the others positive tab.

You can also see my white red and black wires from the first cells balance wires connecting to this cells balance wires which are red black and orange.

these last three basically tie everything together that i was explaining above and shows the main leads coming together in parallel and the balance wires tying into the last set.

Nice way to reuse a lipo. I've got one cell kicking around that I got from one of my puffed 2s batts. I've considered making a 3s or 4s by adding the one cell to another pack.
But I don't like having just electrical tape keeping all those amps contained.

Yeah I used heat shrink to wrap the whole thing up when it is finished. First time foil tape but I'd rather to be able to keep an eye on my cells if they start puffing.
