Y connector using 5.5 bullets.....

[ScarabChris]

.....and 8 gauge wire?

How should I do this as its obvious two twisted 8 gauge wires aren't going to solder into a 5.5mm bullet.

[Doug Smock]

Are you wanting to parallel packs?
Doug

[LarrysDrifter]

Use 8mm bullets

[BakedMopar]

I just solder them together without wire.

[Snowride]

Hmmm, why 8 gauge? Unless you are connecting both to a 6 gauge or bigger I do not see why you need such a large size. Explain the connection to us.

You dont need to use any wire to make a "Y" connector. All the wire amounts to is increased resistance. All you need is something like this. Unless you need additional wire length due to wire routing inside your hull.

Those are nice!

[ScarabChris]

John that is exactly what I need!! What is under the shrink wrap?

I want to make these connections so I can run two packs in parallel. These are 6s batteries and Leopard 5692 1340 KV motors. I went 8 gauge just to be safe.

Ya did you make those or they available somewhere?

Guy's they are easy to make. You just need a big enough soldering iron to get the solder to fill in the gaps. The basic method of construction is to take a piece of 10 ga copper wire, strip off the insulation, tin a 3" length to make it rigid, cut it in half. Take the 2 males and 1 female, lay them down flat on something insulating (dont burn your table!) and insert the 1 1/2" tinned wire to align the three bullets using the holes in each bullet connector. Solder that side in every nook and cranny the iron will reach. Let it cool and flip over. Do the other side the same. Using some dykes (is that spelling right?) to cut the wire protruding out of each side and clean it with isopropyl alcohol. Heat shrink it.

For the opposite side of your packs take 2 females and 1 male and repeat. I have them built for 4mm, 5.5mm, 6mm and 8mm. Very simple and I must admit I did copy them off someone from RRR but its been long enough I cant remember the originator. My hats off to him whom ever he is.

Excellent!

I'll be making some tomorrow!

Thanks for the tip!!

These are exactly how I do them. Here is a "T" version.

I tried making some almost like John's method, but the wire stands kept separating. I think the secret is to keep the wire longer like he described (I was using pieces about 1/2 inch long), solder them up, THEN cut them. I ended up using copper tubing left over from my refrigerator ice-maker hookup instead of wire.

Solid copper wire from hardware or boat store.

Thats what I was going to try, solid copper household wire like Romex. If it can handle 240 volts to run a dryer or oven it should hold up to this.

I also like the idea of soldering the bullets directly to each other.

Excellent ideas here guys.
