Over the past 3 years I have purchased 164 cells. And I have been very satisfied every time. Still have over 100 in the future plans. And I will be buying them here.

Customer Reviews
Overall rating: 4.9 / 5 from 123 reviews.
This is my fourth order of the same cells. They were delivered quickly and undamaged. All cells were at 3.28 volts. I have not built the battery yet, but since it's my fourth I expect the same as all the rest well over the rated 280. Have never needed to contact the company for any problems. My only complaint is these cell cost half of my first build cost, great savings.
Great product, won't purchase these cells anywhere else
I was not really expecting you to replace the damaged battery as I am sure it will be fine but the fact that you did with no questions asked tells that this is the right place to buy. You will receive many more orders from me. Thank you so much.
Cells came on time, and package very well. These are the best Cells I've had so far. I will be ordering more really soon.
Came quickly and perfect. Thanks again
I'm using 4 of these cells with a BMS in a 300 W, 12 V off-grid solar project (Victron 100/30 solar charge controller). So far they are working flawlessly with ample reserve for several cloudy days in a row.
The box on one set of 4 got some abuse during shipment. I suggest more heavy grade cardboard.
As described, well packed.
Seem to be good cells
aaa
I received a order 0f 280 AH lifepoe4 batteries that was missing one for some reason I texted a few messages and finally called and talked to nick who resolved the issue and said a new battery was being shipped. This is a good business to do business with TOP NOTCH. Thank you
Great condition, brand new. It arrived the day after I ordered it. Always a great experience with this place.
First-time customer and great initial impression. Shipping was timely. Cell voltage and resistance appear matched. No capacity test yet. Company quick to correct an issue with shipment and promptly provided a replacement. Nice to have a trustworthy stateside company.
I got 16 280AH batteries and they were flawless. These are still the cheapest priced units within US stock at least from what I looked for. I’ve already gotten 32 of the same batteries and all have been perfect with fast delivery only about a week or little less. I’ll continue to purchase My batteries fro them.
Wonderful, professional group. As I build my battery bank I expect to work with them more!
Quality grade A product! No deformation
Fresh build and 3.28v.
Unbelievable customer service!
Everything is perfect, well packed and they look good. I recommend it.
Excellent value for large capacity cells!

(PRE-ORDER) EVE LF280K V3 Grade A Cells - 3.2V LiFePO4 280Ah Battery - ETA SEPT 28
The 18650 Battery Store delivers an excellent product, at the best price! I have ordered lithium batteries from this vendor on multiple occasions and always received the product on time, in excellent condition, with excellent packaging. I will never go anywhere else to buy lithium batteries again. This is the highest quality I have ever seen in EVE LIFEPO4 cells. Out of a total of 48, grade A cells that I have purchased in the past, every one of them were the same exact resistance and voltage, and were top balanced to within 1mv. I highly recommend the 18650 Battery Store to anyone needing this type of battery and misc. electrical supplies.
Best Price, Quality and Service Period! Building our 10kwh 36v nominal battery bank for our off grid homestead with these Excellent grade A 280 cells! We've researched worldwide for two years and 18650 proved Tops! Highly recommend and will buy from again! Thank you 18650!
Really are Class A. Exact same voltage and resistance for 8 cells. All charged to within 4AH of each other.
The team has been great to work with. Easy ordering and very fast shipment. Received in 1 day. That was good because I was replacing a weak LiFePO4 cell in my solar pack (not from 18650Batteries) and had to get it fast. Thanks, folks!
Batteries were promptly shipped and delivered. They were well packaged. Both packs of 4 (8 total) measured the exact same voltage and well balanced.
We order a lot batteries from 18650 and have great service from them. We are very happy with their service and products.
Ordered these cells and they arrived quickly! Original EVE cells which looked great and work even better!
First quality grade A batteries. Packed very well. Quick shipping.
