I thought it did well once it leveled out, I asked my daughter to stay away from the battery while it was discharging, she asked me are we going to pop it dad lolls it did get bloody hot but did well.
Charged the batteries yesterday let the batteries rest over night then today discharged. (remember all my test since post number 85 have been with the protection PCB,s removed)
Cell Adischarged from 4.15 volt to 2.5 volt at 0.5 amps
In your first test with the PCB and 0.5A discharge, the cell was charged to 4.2V.
This one is starting from 4.15V, so theoretically the 3100mAh should have been achieved if the cell was charged to 4.2V
But for those charging to 4.15V is a good reference point.
Looks like we have some good cells with POS PCB's! The protected are useless for most of us unless running them in parallel or in a low draw/high capacity uses.
If you can get these cells with a kallie's pcb you will own the market!
To be honest with these cell after being rested from a full charger the voltage is around 4.18, the rested voltage of this cell was 4.159 after being rested, it might of droped 0.021 volt or so for sitting on the charger to long, before i removed it.
It would be a good test for people say using xtar chargers like the one i test a little while back they seam to cut out around 4.15 volt, better then over charging and the cells would last bit longer, but from 4.18 or 4.20 they would hit 3100 mAh no problem.
Im doing a 0.2 amp discharge from 4.163 volt to 2.5 volt for you now ill post the results tomorrow after work, the starting voltage of the discharge was 4.163 volt with a 0.2 amp load, i know its not 4.18 or 4.2 volt but that was the rested voltage after i charged it yesterday for this test, i thought it best not to try and top it up the rest it again.
I hope you still find the test useful.
What alarmed me was the such low mah testing with the pcb,s.
redilast and aw sell the same cell,s with good pcb,s but the price is higher.
Charged the batteries sunday let the batteries rest over night then yesterday discharged, this test took almost 15 hours just to discharge. (remember all my test since post number 85 have been with the protection PCB,s removed)
Cell Bdischarged from 4.163 volt to 3 volt at 0.2 amps
Data table
Volts Vs mAh
Volts Vs Wh
The cells starting voltage was 4.163v with a 0.2 amp load, the cells resting voltage after a few hours was 3.24 volt, it almost gave 15 hours of run time, but this test was ment to be to 2.5 volt not 3 volt, my bad.
just stumbled on this thread! A lot of useful info here... I don't mind unprotected batteries, but I'll keep an eye on this thread to see if intl-outdoor get's these ncr18650a with better quality protection circuits. If so, they're a great buy.
