yes, this is (almost) how i do it I use full tabs and route the awg through one hole and solder the copper flat to the middle part with lots of solder, works under hard conditions.
haha, nice. I thought about using the full tab as well in that way but Iām trying to double the number of connections I can make
Just make sure that you donāt lose the full contact patch to the screw terminal
Just a quick note. Soldering is by far worst way to make connections. Signal wires, ~ok, but power connections best to be avoided. Solder has poor conductivity and is hard, so it might break. I have stopped soldering. Got couple cheap crimpers and use non insulated terminals everywhere. I dont say ādont do itā only explaining the right way of doing it
Are you talking about for this application, or in general?
This is a very tricky subject youāre taking a hard stance onā¦
If you want to find something i usually do google search and not on site. Enter āM5 ring tube lugs amazone.comā in google, then switch to image view and check the ones that look similar of what i have. Imperial should be 1/5" if there is such thing
I see a1parts have some, part DK1359D

In general which includes this application
Well, Iāll have to say youāre wrong.
What you meant to say is, itās probably a bad idea to use solder for power connections because itās very hard to do well, but when done well itās better than a cold weld crimp.
I did not meant that. If you look arround all wire terminals from oemās are crimped and not soldered. Automotive, general electronics, etc. Again, solder is a bad conductor, it breakes, it can go loose if power flowing exeds safe operating limits and cable heats up. I am ok if you have another view on that but my science does not go with that.
I agree with all these points and I know that all high power applications use bolt on connections.
But for the conductivity argument, I am skeptical.
Yes, in vibration prone settings, such as in Automotive, a cold weld crimp is better.
However - solder IS better for power connections. Unless we have a different meaning of ābetterā
Itās really a situational thing. But in a vacuum where nothing is movingā¦ solder is a better power conductor than a crimp.
Thereās cold flow.
OK, vacuum is happening in space I guess you would agree that scateboards would have far greater vibrations than vehicles on suspension? And my initial argument was valid? @mishrasubhransu, please do look at this: https://www.google.lt/url?sa=t&rct=j&q=&esrc=s&source=web&cd=22&ved=2ahUKEwjM0_DGibXiAhUhlYsKHWIfC6kQFjAVegQICBAC&url=https%3A%2F%2Fwww.avoutlet.com%2Fimages%2Fproduct%2Fadditional%2Ff%2Fiacs_of_metals_n_solder.pdf&usg=AOvVaw2-5EpyP-XhRNWmL2iRpZVr Now answer if its better that coductor is touching connector wall and in between strands or it touches in places with a mix of solder? Maybe my logic is flawed but i have not come to that conclusion yet.
I think in EU soldered connections are not allowed. Thats why Prusa started doing crimped bed heater connections on their printers
If u get a good crimp connection itās copper on copper with no air and not with low conductivity solder between. Lower elec resistance. And less likely to break or no cold flow. If u get a fancy crimper they will literally press the materials together making essentially one wire
Yeah - I have the 20 ton hydraulic china crimpers flooding amazon for like $30-40.
Using tinned copper lugs on 2/0 welding wire, it literally becomes a solid piece of copper, even when looking under a microscope. Pretty dope for how cheap the crimper is.
wow did you really look with a microscope? I wouldnāt know what to look for. I remember finding a tool that was stated to crimp hard enough to fuse the metal and it was thousands of bucks. Maybe for 40$ yours does it. doesnt matter the canbus will fail first.
anyone use any other svelte connectors instead of the screw terminals?
People have been soldering cables to bullet connectors for a very long time in the RC world, I donāt see much difference in this situation. Maybe both methods are good enough?
Best practice and method wad discussed. Both are good enough. This is my recent build and i have 2 soldered connections to charger connector
Anyone using Inventor or Solid works here?
