I bought a couple VTC4 batteries earlier this month, they worked great until this morning.... I popped them both in my Sig 150 (only device I use them in) this morning, I capped for about twenty minutes before I noticed the power being cut off half way though a vape. When I looked at the screen it said my batteries had a 40% charge left. I took them out and put them in my charger. One was down to 3.43 volts, the other was still at 4.07 volts. What's the deal!? Is the battery just a dud, or is the Sig draining one more than the other?

Are they a properly "married" pair? Small differences (internal resistance, age, capacity) are amplified and heavily consequential when batteries are stacked -- eg: way imbalanced draining. I assume you've got them marked "A" and "B" or some such, so that you can exchange their relative position inside your mod on the regular. And that you're always charging them together and fully, with each cycle....

Otherwise, sounds like one of them is older/lazier than the other.
