CDR = continuous discharge rate. This value represents the safe level of amps that can be drawn constantly from the cell. For vaping this the
only value worth adhering to. Some companies will show pulse ratings on their products. This value should be ignored.
I'm not going to provide proof, you are just going to have to trust me on this. Efest are one of many companies that take B or C grade castoffs from Sony, LG and Samsung, put their own wrappers on them, then inflate the price and specifications. These cells are then aggressively marketed at vapers who trust the specs, and use them way beyond their capabilities. Needless to say this is a truly sh*tty way to do business.
Efest are one of the worst offenders. I personally boycott all their products and encourage others to do the same.
We are in the highly privileged position of having ECF member Mooch, who tests batteries and publishes their true CDR values allowing them to be safely used.
Here is his test of the cell you are using. Initially found to have a 20 amp CDR, he later tested another of the same and found that they had (unannounced) changed the cell under the wrapper to one that only had a 10 amp CDR. Draw 35 amps from a 10 amp cell and you stand a high chance of picking teeth out of your cheeks.
NB. Don't
'toss' any build on a mechanical mod without fully understanding their use. Used incorrectly they can be hazardous. Make sure you do all the required reading and research first. Anything you are unsure of, just ask.
