What is the typical stopping voltage to set your tester when capacity testing 18650 cells ?
Thanx

Depends on chemistry

LFP = 2.5V
LTO = ?
NCA/NMC/LMO = 3.0V

Ok, thanks. I checked the datasheet for Samsung 30Q and they state 2.5v. I'm using ZB2L3 tester. The listing page of the seller says
stopping voltage is set with + - buttons with voltage after P. Default shows P3.0 but it doesn't stop at 3v. Latest test, it stopped at 3.25v.
I've also had it stop at 3.4v. Well, I'm not building battery packs so capacity isn't that important. But I did want some idea about how much
of original capacity was left.

If your tester is the 2 wire variety, the voltage sag on the wire from the load often causes the test to stop prematurely.
The 4 wire tester alleviates this issue, somewhat.

My tester stops at 3.0 volts
