Description

Samsung 30Q Li-ion INR 18650 Battery

Huge Capacity = Less Charging

With a 3000mAh capacity that makes other 18650s look like pipsqueaks, Samsung's 30Q is a never-ending well of power. You'll recharge this massive power tank less often than any other battery you've used in the past. Free yourself from the USB cords and wall chargers! For powering electronics at lower amperages (15-20A), you'd be hard-pressed to find a finer battery.

The best Yet for the Money
I purchased these, with the intention of building USB charging banks out of them. They seem to be really good batteries. I test all of my cells before I install them in a power bank and these are true to their rated capacity. Most were at 3,000 MAH or a little under or over that capacity. For the money I think that these are pretty good quality. I would recommend them, at least for a battery bank. Not sure if they would be good for a Vape product.
ProsCheap Price. Good power reserve. Not over rated.
ConsNone that come to mind.

Hold a Charge well!
So far so good, my first time using these type of batteries, but do far they work like a charm. They seem to hold a Charge really well, but they don't last real long. I'll probably look at something with a little more holding power. Overall they seem to be ok.

Couldn't get anyone to rebuild the battery pack for my electric screwdriver. So I did it myself.
Replaced the lithium batteries in my cordless screwdriver and now it works like it's brand new.
