No, I’ve been buying 2500 mAH batteries rated for 20A draw for 5.50 a piece, mostly Sony and Panasonic from illumn

I am curious, what kind of projects do you do with those batteries, what is their use for? Thank you

E-cigarettes or cannabis vaper if I were to guess, this is (other than RC drones) the only thing where you need the rated discharge current.

They’re very popular in the boutique flashlight industry

Bingo, it’s the nicotine vapor

I use 18650 cells over pocket cells in my hobby projects if possible: partly because I find it easier to get consistent quality 18650's in my local market (shipping lithium ion batteries is a hassle), partly because it allows me to use the same pool of batteries across many things (power banks, torches, different DIY-projects).

What battery holders do you tend to use?
