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.

Excellent and genuine Samsung 30Q's
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
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.

Samsung Battery
At first the battery lasted about 7 hours but shortly after would only last about 4 hours.

Exactly as described
They charge up quick and seem to hold their charge well. Im using them in wireless desktop fans... get an easy 4 hours out of each battery, at full power.

Almost the Best On The Market For Power Tools..
I call the 30Q "LGH2's little brother." ;) Put them in my Milwaukee m12 battery pack and I can't complain a bit about performance or capacity. Also I use it with my impact gun and hackzall and it powers both beautifully.
