This is an outstanding cell for those who like high capacity without sacrificing a lot of discharge/drain capability. This is cell is a competitor of the well-known Sony/MuRata VTC6 cell, in which the Samsung 30Q performs very similar and closely with. Many consumers will argue the better of the two, although that is subjective to each persons own demands and needs for their device. This cell has a high capacity of 3,000 mAh in energy and a true maximum continuous discharge/drain rating of 15 amps without any temperature cut involved. It has an outstanding cycle life as well and that should be definitely considered in your purchasing decision, along with its other attributes as well. This cell runs very efficiently and is very stable when used @ 15 amps. This is another great cell that many use in power packs, higher output power banks, BMS's, power tools, and high performance flashlights. This cell has proven itself time and again and is very versatile for may applications.
Got four of these 21700's and four 18650's. Charged them up and late the next day they all registered at 4.07+ volts, so very little loss in over 24 hours - miniscule. Will buy more.
Batteries arrived on time and work. Very good thank you
Good quality and great capacity. What more could you want?
researched 18650 batteries this was one of the five best recommended, working great.
Quick shipping, friendly service, batteries work great. Thanks!
Excellent batteries! Bright flashlight!
Great batteries for flashlights. I use these in my Small Sun and they last a very long time on full power. Will be buying more of these from 18650batterystore as needed from now on.
Great customer service and fast delivery.
Great packaging and quality cells. Built a pack for my esk8 12s4p. No issues so far.
I bought these batteries with a charger. They are awesome thank you guys for a great product
Great Service, Awesome batteries
Both Samsung 30Q Batteries arrived earlier then expected and are working well so far. Thank you!
Great batteries. Well made.

took too long to delivery.
Excellent batteries. Works great, lasts long. Amazing price, thanks
Great battery. Good price. Exactly what I ordered
Great service. Fast and exactly what I ordered. Good job. You guys are the best. Thank you
Create a small battery pack as backup.
Until now these batteries do the job perfectly.
Always authentic batteries at a great price!
Really good price on these batteries and the shipping was really quick. I definitely recommend!
Original 3-year old batt pack in hand-held portable vacuum would run out of power in less than 5 minutes even with a full charge. Replaced those with these Samsung batts and now the hand-vac runs good as new, perhaps better !! Great batts, thanks !!
So far, so good! Came promptly and work great. No complaints. I did get confused and think they came in pairs, so I thought I had ordered 3 pairs and actually ended up with 3 single batteries, so learn from me and don't mess that up! ;)
Tracking information was available as soon as my order shipped and it arrived quickly and safely.
easy order, quick shipping. Very satisfied. thank you.
I didn’t realize how bad my old batteries were till I put these in. The last longer and stronger than I remember the others. May just be me but good product and fast shipping.
Quality batteries at a reasonable price. No complaints from me.
Have not yet implemented it into my project. It arrived in a timely fashion, was well-packaged, and is assembled with good fit and finish.
These batteries are amazing long lasting and power till it's completely exhausted
quality batteries ; fast shipping and professional support ! thanks
They were fast,easy,and had authentic batteries! Will buy again from here!
With 7 of these, I have managed to revive a stick vacuum, Electrolux EL3020A, with 25.2V battery.
The vacuum, seems like has even more power then when it was new. Last much longer as well.
Fits perfect for those mods with small battery compartments.
These batteries are perfect for under 45 watts. They go well with mouth to lung vaping, and can pair together in a dual battery mod, going up to 90 watts. I have only used these for a single 18650 battery mod, my Aegis Solo for mouth to lung vaping. The current Samsung 30Q I have in there isn't even halfway dead even though I vaped on it a good bit last night. I was recommended these batteries from one of Battery Mooch's videos. I highly recommend these batteries for mouth to lung vaping!
Very fast delivery just order was 12 cells short .I emailed them letting know the issue.fast reply saying sorry and extra cells were sent
Pretty great batteries for a flashlight. Can't really complain. Just make sure you really need unprotected cells.
I used these cells to rebuild and upgrade my DeWalt 20v Max battery packs that were too old to hold a charge. I now have 50% more run time over a new 2AH battery and I did it for about 1/4 the price of a new battery. I'll be back for 10 more batteries soon to rebuild 2 more 1.5AH packs. Double the runtime for 1/4 the price! Love them! Here's a video I made of the rebuild: https://youtu.be/91e9ZEGWulc it will be live on March 29th.
Excellent batteries, I never choose another 18650
Great battery would recommend to everyone
These batteries are superb. They lasted me two years the last time I purchased them so I’m sticking with them. Although the printing says “not for e-cig or vape” this is exactly why I use them and they have never given me a problem. Use a properly working vaporizer and they will work just fine. The price was decent and the shipping was fast. Thank you!
Excellent batteries. I usually get LG HG 2's but they weren't in stock. These are a prefect alternative.
Getting way better battery life on a certain device that produces vapor after replacing my crappy ones with these samsung ones.
always very fast shipping and excellent quality for use in my high output led flashlights

This is the reason I use this service. I have ordered many times. I'm only here to say that I have always received prompt shipment with my orders.
Theu arrived promptly and work perfectly
Awesome batteries. Better than the green wrap Samsung's.
My Hoover LiNX vacuum cleaner battery pack was getting weak. It uses five Samsung INR18650-20Q 2Ah 15A cells. I thought I'd try the Samsung 30Q 3Ah 15A as an upgrade. Unfortunately they are soldered into the controller board. It took a lot of effort and care with a controlled temperature soldering iron to install them. But it works great now with much longer run time and apparently more delivered voltage to the motor based on the sound of the motor and effectiveness of the vacuum. I'll be buying a second set to upgrade the spare battery pack.
Fast shipping! Great customer service. Already placed a second order.
Great batteries at a great price. Bought to replace some batteries I've been using for a couple years and these are fantastic. Also came in battery cases to protect each set of 2. Awesome customer experience
Work well as expected.
Rechargeable and works great
Batteries came as expected, and they work great. Couldn't be happier.
Good place to buy 18650 batteries, but be careful when ordering - I accidentally bought batteries w/o "buttons" - my fault for not paying attention. I had to add a bead of solder to them to get them to work in anything I owned.
But, I can definitely recommend 18650BatteryStore.com - got exactly what I ordered and pretty fast. Just be sure to order what you really want.
I bought 26 of Samsung 30Q 18650 3000mAh 15A Battery and 18650 Battery Terminal Insulator Rings to build Li-Ion battery packs for my drones (3S and 4S packs). They performed really well and capacity of the Samsung 30Q 18650 3000mAh is (true) as stated in datasheet. Batteries were delivered fast and well packed. Satisfied. Will buy again.
It would be great if you sold the protection circuits, kapton and heat shrink. Maybe some chargers as well. Your service is fantastic. Thanks!
Great batteries, great shipping and great price!
Batteries seem to be in good condition. Just put it in my flashlight and it worked. It was on sale and the shipping fee was quite reasonable.
I received My order of samsung 30q 18650 batteries in 2 days made one 2cell for my hubsan 501s quad made a 3cell for My zeno quad flight time is as good as hubsan battery at a much lower price very best people order from will buy again
Great batteries, always fast delivery!
So far works great, charger rules
Arrived on time and as described! Great company to do business with!
Reasonable price with fast shipping. Have not tested capacity as of yet but the cells seem genuine.
Fairly easy website, good product.
Great place to get your 18650’s. Good price and quick delivery!
Tested battery capacity and it was 5% above the rating.
Almost went to another source because nobody answered and I thought a valid number would at least have an answering machine.
Shipping was fast despite the pandemic. And the batteries, in my opinion. Are perfect for my e-mountain board. Thank you again.
I removed old batteries, peeled off the connecting strips for use on the new batteries, positioned the new batteries to match the old pattern, soldered the connections while keeping the insulators intact, installed the assembled pack into the vacuum cleaner, and tested. Voila! perfect!
Great battery. The company is great to work with:pricing, selection, and shipping are awesome.
Great batteries, they last a long time!
Love them! I’m running a Valyrian II with the Valyrian 3 battery mod. This sucker now runs for 2 days + on a full charge. I bought 6 batteries. Came quick and brand new original product. Will definitely buy again.
They work great, long lasting!!

Very good batteries! Use them in my Vaporesso GenX! Last at least 4 tanks using Geek Vape Zeus!
Perfect size for my flashlight
They shipped the same day I ordered... I had a question for them so I called. It went to voice mail, so I hung up. I hate those things. A few minutes later the phone rang. I didn’t leave a message. I answered the phone it was support from 18650 Battery Store. He explained that he was on another call when I called and could he help me. I asked him what I needed and he took care of me right away. We ended up talking about batteries for 10 minutes or so. Of course I had bought the right batteries for my device.
Companies don’t do that much nowadays but it sure made me feel good to know they care about their customers that much.
Thank You to The 18650 Battery Store.
Bought them for my husband, they are what he wanted. They work great and do the job!!!
Quality batteries at a good price... Thanks!
Thank you! Batteries are all working perfect in my flashlight.
Delivery was quick. I have not yet assembled the product into a battery pack.
Used for vape...Batteries are great, price was about 1/3 of what we usually pay in the store.
Accurately described, came quickly, well and safely packaged.
Batteries are top notch!
The batteries work great everytime I get them
Excellent batteries from an excellent store. Thanks guys!
Jose ramon S.
Love this company! Fast shipping, great prices, would 1000% recommend!
Great battery and fast shipping
The batteries performed perfectly and had a higher capacity than the old ones.
Battery life is very good with both sets of batteries and I will be coming bk soon arrived very fast
I use these to rebuild all the battery packs for our bike lights. They transform our lights. Before on high, best case you would get an hour on high. Now with these batteries I have run them as long as 5 hours on high with no dimming. I have no idea how long they would last now. Simply amazing!!!
My order was a total of 3 days from ordering to delivering! I love this website!
Exactly what I needed & they work great!
