I ordered 5Ah pack. It has vtc4 5s2p with ZK05 date (05th of Nov. 2017) that makes it 4.2Ah, basically 4Ah battery. I would expect Samsung 25r to make it 5Ah battery. At least it has Sony cells (hopefully genuine) instead of some no name Chinese battery. 3 out of 4 bars were on at 18.95Vs. which means 3.79V per cell. Close to storage voltage. that pack could theoretically give out 60A (but I doubt

zsd Martin,thanks for the info, even though it is disappointing. I'm not sure whether the good reviews are from people who only try to draw 20 mA or people who don't know that they are getting oscillating voltage. Or maybe you had bad luck and got a defective one. I bought one but have not tested it yet, I was hoping to do so soon. I plan to submit my review when I test it.

Unfortunately, there is very little to recommend for this module. For a load current of only 1A, I tested the buck, boost and current-limit performance. In buck mode, output voltage was very noisy however the module did appear to be stable. In boost mode, with the output voltage set 3V higher than the input voltage, the module began sinking a ridiculous large amount of current from the input. Current-limit

zsd This review looks like something translated from another language by a computer. I'd love to know what you really meant!

The drills were in intense contact in the plastic bag: the result is unpredictable; the blades are non-extinguished, the helix blade on each drill bit bruised - holes. Under no circumstances is HSS material very soft when removing burrs and surpluses after scraping. In no case does the surface finish correspond to the picture. The enclosed sheet lists in part other drill bit diameters than actually
