They really, really are not (more than sufficient), Andria.
When it's time to buy new batteries, take our advice and a get a couple of those:
They are generally considered the best and safest for vaping. You want to be safe.
I have Samsung and LG HG2 and I'm very happy with them. I've also used the AW IMR (orange) batteries in my Provari for years because ProVape recommends them, but the Sammy and the LG are much better.
I get my batteries from RTD Vapor--I trust them and I've been using them forever.
I get AWs from sweet-vapes.
