Authentic 30Q, 3.7V Flat Top Real 3000mAh 18650 Battery Rechargeable Samsung30Q(4 Pack)

This is my 4th set and they are great little batteries for the price and definitely genuine.f I did have one die on me after about a year but, that is something that can happen with any battery. I use these in my vape and also in a rekon 35 drone. I can easily get 14 minutes on my drone with my vtx set to 100 mw. I can get aroung 11 minutes with it on 200mw so these are great.

Appears to be genuine and charged well. Fit my pack nicely.

I have used them to repair two Dewalt batteries? The batteries are working great.

Works perfectly

Not the best, a lot better than the worst ones I've bought here as far as capacity, and life cycle goes. The worst ones were the ones that claim a ridiculously exaggerated capacity.

By a review on P.F. This was one of the better brands he tested. But, one, only charged 1 time, and nothing after that. The other 2, I used longer. Recharges 3, maybe 4 times, and they died. Seller trys to tell me I discharged them too far. Well, was using in flashlight, and the power button would flash RED when battery was getting low, so, I would remove them, and put on the charger, OR charge in the flashlight. But, they quit taking a charged. Seller DID replaced the 1st bad one. But not the other 2. The 4th battery, is in a flashlight I just dont use hardly any, So, it hasnt had the cycles the other 3 have had. And the replacement battery, I believe, has died also now. I had them marked.

Bought two packs (8 batteries total)Arrived in a few USPS/FedEx insulated bags wrapped into each other.. Inside of that were the plastic containers holding the batteries. Those were a bit smashed. But the batteries inside had no dents, scratches, oddities otherwise.Physically, the batteries look like legit Samsung 30QsDid some measurements on the batteries:Weight was around 45grams per each battery ✓Voltage was good ✓ (~3.55v out of the plastic container, charged up to 4.2v, 3.6v nominal after that)Charge was good ✓ (charged to near ~3k mah or above on each battery)I didn't check amperage (15amps) out on the batteries, but I would assume it should be fine. If that turns out not to be the case, I'll report back here.I charged one slow at 0.5amps (approximately 5.5-6 hours), and later on I upped the voltage a bit to 2 amps (wasn't paying attention here but less than 2 hours I think). No issues.

There are no batteries higher than 3000, bc it’s the max the technology will go. 9900 mAh batteries are fake. These are the real deal and as high as current tech can go in milliamp hours.
