Silicone Stranded WIre Guage

by TheNationalBureau on Mon Dec 23, 2019 1:06 pm

Hi all, I have these battery packs.

https://www.adafruit.com/product/4193

They each power an LED. I needed to do an extension of the wire from LED to battery pack and wanted to solder in some extension wire. It was recommended that i use silicone stranded wire for the flexibility/strength. Like this: https://www.adafruit.com/?q=silicone%20stranded%20wire

My question is what guage of wire do I buy? I wanted to match the wire that's already part of the battery pack.

Thanks!

Ryan

How long of an extension? There's always https://www.adafruit.com/product/1131 is the length is right.

The stranded silicon coated wire is amazing stuff. For power use, I recommend 26AWG (which will handle up to 3ish Amps). For logic signal connections you want the 30AWG stuff. Even the 30AWG wire will handle 800 mA so will be fine for a single LED.

Thank you Dave! You rock. One more quick question. That 26AWG wire.... Will it handle a 4 AA battery pack as well? I also have a small fan powered by this pack that I need to extend.

Thanks again.

It depends on current, but AAs will be well short of the 3A rating on that wire.
