What gauge wire is used in your batteries?

Post by marcsg »

Hi, I previously purchased this 3.7V 2500 mAh lipo battery (https://www.adafruit.com/product/328) and I was wondering what gauge wire it uses. It looks like 30 AWG, but it doesn't say anywhere.

I ask because I removed the connector and placed the individual wires in terminal blocks, but the blocks have chopped off some of the wire strands (and I will need to continue to remove and reinsert the wires for charging). Regarding a permanent solution, I've read that tinning is a bad idea because of the mechanical pressure from the blocks, and instead I should use ferrules. These are the smallest ferrules I could find, (https://www.digikey.com/en/products/det ... 014/266404), but they only go up to 28 AWG. Thanks!

Those use 24 gauge wire.. twice the diameter of 30 gauge, and four times the cross-sectional area.

For terminal block connections, yes: ferrules are probably the best choice of wire termination.

Note that we recently added a ferrule assortment to the store: https://www.adafruit.com/product/5131
