Samsung INR21700-40T 4000mAh - 35A

Ordered 90 for 6p 14s battery, around 2/3 of them came with voltage 3.43, the rest was < 3.30, several were below 2 volts, and one was 0.8 v ! Which for me means that batteries haven't been stored in equal circumstances, or probably the seller has mixed old and new ones. Performed capacity test shows that average capacity is around 3750 mAh (discharging from 4.15 v to 2.5 v at 0.9A). The one which came at 0.8 v also scored near 3700 (at least it has some capacity left). Giving a 3 of 5 stars. Although fair is 2, voltage below 2 V is not healthy... Now looking for the LG cells but I really hesitate, I don't know what to expect... (Posted on 08-04-23)

Fantastic battery, good price, good store? Review by Frank

Hi I bought these cells, to build a 6s pack for a 7inch long range drone 1200kv motors. these cells offer more capacity / weight than lipo, but indeed discharge current is lower, so to be gentle on the throttle. For moderate flying and cruising this is perfectly fine. Maybe we can get current further down, by moving to drone setups and LION, become serious contenders against LIPO.

This Samsung 21700 battery is currentlyone of the best cell at the market, the other contender would be the Molicell INR21700. Both have better performances than 18650 or 26650 sizes.

NKON is a reliable source, quick shipping decent prices.
One advice, could you include the IR value for the cells in the specifications?

Superb battery for vapers but Samsung 30T is overall better for Mods with one battery. (Posted on 22-01-19)
