Excellent and genuine Samsung 30Q's
March 1, 2019
I ordered 4 of these to build a portable charge pack for a heated jacket. I tested them in a LiitoKala Lii-500 4 Slots Smart Intelligent Battery Charger bought from Banggood.com. All four batteries tested at or above the 3000 mAh nominal rating. Some in the 3200 to 3400 range after cycling them a couple of times to condition them.

Beware of buying these from Chinese companies or on Amazon; many are counterfeit in that channel. It appears BatteryJunction carries the real goods at a good price point.

The best Yet for the Money
December 22, 2016
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.

Good quality batteries. Easy to solder.

High capacity, high drain batteries. They worked with the dustbuster as expected. They hold the charge well. So far so good. Time will tell the longevity.

Good replacement for a solar yard light
November 26, 2019
I got a bunch of solar powered motion sensing yard lights that came with underpowered batteries that wouldn't last very long. I use this battery to replace them and now these lights work nearly all night! Very pleased with the price and performance.
