Samsung 40T 21700 4000mAh 35A Battery - INR21700-40T (40T3)
Samsung has really hit some "Grand Slams" just in the past couple of years with Li-Ion cells, this Samsung 40T is just one of those examples. What makes this cell so special is it's ability of having "Maximum Balance" with Very High Capacity and while having Ultra-High Discharging/Drain capabilities without any compromise, this was previously thought to be impossible as you have only so much room in a cell for either Capacity or High Drain, Not both. Samsung has become the leader in the R&D department as of lately, this Samsung 40T is just one shining example of that. Having a legitimate 4,000 mAh in capacity with a 35 Amp True Constant Discharge Rating without involving a temperature limit cutoff and not making the cell over worked, is nothing short of Amazing. This is the hardest initial hitting cell made that has a legitimate 4,000 mAh or greater in capacity. With this cell you can have a true "Peace of Mind" that your demanding needs and wants will be more than satisfied and met with no problems. This is a truly a Phenomenal cell in the 21700 form factor size.

Can’t say enough good things about these cells. Purchased to build my own 10s2p battery pack for my Meepo v3. Over 100 miles post build and no issues whatsoever. I was so pleased with my first set of 20 cells that I purchased and other 20 to build another pack for my brothers board. 10/10 would highly recommend this company and cells.
John S.
The Samsung 40 T is definitely one of the best 21700 batteries on the market and i highly recommend it. I also highly recommend the 18650 battery store because of their excellent pricing and fast shipping.

21700 battery were not packaged correctly
Ordered 6/ 21700 batteries..they were put in cases and thrown in a big box without any bubble wrap of any kind..they were banging around during shipping and all the cases were shattered..they don't seem to care about safety or that you spent $ with this company..I will not be buying from them again.

Long range batteries for FPV
This is one of the best Li-ion batteries available for long range FPV. Light weight, 35 amp constant discharge, even though I mostly am pulling 10-12 amps flying long range I can still punch the power or fly quickly without stressing the batteries.
Don

I have very fast received the batteries ! As well I had a small issue which was promptly fixed by support team ! Strongly recommend to buy from this place ! Thanks
Tim
Not 4000mAh
These are really good batteries but they are more like 3800mAh of useable capacity. Very low internal resistance means they stay cool when charging fast, my charger can do 3A and they could handle at least another 2A before getting too warm while charging. Overall one of the best 21700 you can get and at a great price.
Richard James

Samsung 40T Battery Review

Ryan McManus
Wrong batteries, need a return
I ordered the wrong batteries and contacted the company to request a return. It’s been 2 weeks and I haven’t received an email back. But they emailed me to request I do a review. It’s not the companies fault that I ordered the wrong batteries but I would appreciate an response to my original email requesting a return.
Jason T.

Nice batteries, nice price, super fast shipping. 18650 Battery Store is no joke. I always buy my batteries here.

Unsure
Unfortunately, I only purchased one of the two batteries I needed, so I havent been able to use it yet. But I can say the package came quickly and in perfect condition. Im sure I will be ordering the second battery soon!
Chris Eck
Very happy
I am very happy I found this site. I ordered 2 of these batteries for a vape mod. 21700 batteries are not cheap in a vape shop. They usually don't have much of a selection either. These batteries were a great value. They have a high mAH and still don't sacrifice too much when it comes to discharge amps. They last a really long time. I bought 2 of these for less than the price of one that I've seen 21700's anywhere else and these are a better battery than most places have
Kenny Schiller

Samsung 40T Battery Review
The batteries are definitely genuine Samsung cells and they work fantastically.

Wrong batteries, need a return
I ordered the wrong batteries and contacted the company to request a return. It’s been 2 weeks and I haven’t received an email back. But they emailed me to request I do a review. It’s not the companies fault that I ordered the wrong batteries but I would appreciate an response to my original email requesting a return.

Can’t go wrong
Nice batteries, nice price, super fast shipping. 18650 Battery Store is no joke. I always buy my batteries here.

Unsure
Unfortunately, I only purchased one of the two batteries I needed, so I havent been able to use it yet. But I can say the package came quickly and in perfect condition. Im sure I will be ordering the second battery soon!

Very happy
I am very happy I found this site. I ordered 2 of these batteries for a vape mod. 21700 batteries are not cheap in a vape shop. They usually don't have much of a selection either. These batteries were a great value. They have a high mAH and still don't sacrifice too much when it comes to discharge amps. They last a really long time. I bought 2 of these for less than the price of one that I've seen 21700's anywhere else and these are a better battery than most places have
