Can anyone recommend a good crimper?

[guerney]

20-28AWG: small signal wires.
The die is the key, they have specific size and shape. 20AWG = 0.81mm, 28AWG=0.32mm in diameter.
you need the right crimper to do a good job.
Show us pictures of the connectors you want to work with, I can make recommendations.

...and here are photos of the ends - they do look about 3.9mm or 4mm in diameter. What crimpers do you use at the Woosh factory?

I'm going to figure out this hands on ebike electronics stuff, even if it kills me.

So this crimper quotes AWG 24-14:

...sorry, it says it's a IWS-2820M, further down the page. I may well buy this one, thank you.

Would love to know what this means:

"Crimping Range: 28-20AWG (0.08-0.5mm2) "

Typically battery wires should be 14 or 12 awg.

Typically battery wires should be 14 or 12 awg.

The red one is thicker than the black one, I'll measure them when my new electronic guage arrives. Can't see any markings.

If you are useless at soldering that must mean you own one, so practice, it's a much better skill to have than the best pair of crimpers. I'm sure there are plenty of tutorials on Youtube.

I'm feeling intense pressure from the experts to learn soldering, and it's good - I'll crack this soldering lark! Even if I burn another dozen controllers! Horrible disasters like the one I've just had can be instructive. I might crimp AND solder connectors. Is there a particular solder brand and/or type you would recommend? I'm hearing that a tin/lead mix is better, also thicker solder is better. What about flux? Do you use flux which isn't integral within the solder?
