Limitless Soldering wires together

[Fenwick17]

I'm gonna add some wire to the battery side of my esc. Not sure if I should twist the wires together and then solder or just butt them together and solder. Does it matter?

Put em together and solder...never seen any other way to be honest

I would use 8mm bullet connectors but that is just me, this route also makes it easier to switch to batteries with different plugs, go from 1 batter to 2 ect. A solder joint creates a weak point in the cables that is susceptible to breakage and idk how well butt connectors would do.

This is what I am talking about doing.

Thank you, I didn't mean butter connectors. What I meant was sticking the ends of the wires together and soldering together vs. twisting them together and then soldering. I think I will take your advice and use bullet connectors. For future jobs would you twist together and solder or just stick ends together and solder. I have lots of experience with wire nuts, butt connectors, etc. Not so much soldering wires together.

I think twist.

Thank.you again

I use female 6.5mm bullets and solder in wire to both ends on each pre-tinned bullet, then heat shrink it all together. Tried twist soldering bare 10awg wire the first time, not as clean and greater opportunity for cold solder for the inexperienced. With snake clamps you can create radii or straights much easier depending on location of extension point .

I had to do it like this once because I didn't have any bullets to use & the tp motor wires are already tinned. This is Jay's Budweiser Buggy & it's held up so far Not sure if that is recommended or not

Great idea...thanks

That's good to know..thanks

Have the wires already been tinned? Or still open stranded wire?

If still open stranded wire, face the two at each other end to end..
slowly massage the strands into each other keeping the wires in line..
pinch the strands once they are mated to make them uniform, solder and heat shrink..

makes for a much cleaner looking solder joint compared to a side by side solder joint, especially in the larger gauge wires..

It will usually pull solder quicker and flow better throughout the joint as well..

Camaroboy hit it perfect... example here:

This is an incredibly robust method for soldering two low gauge wires together. It definitely addresses the issue of solder joints creating a weak spot along a wire. Video is under two minutes.

Excellent!!!
