Perfect Review by Cannabiz
These are the best Batteries for Ezigarettes and for both Mech Mods + Normal ????????????????????

Really Good for Mods with 1 Cells. Top ???? (Posted on 02-03-20)
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?

Samsung 21700 40T Review by Alain
Très bonnes batteries reçues en quelques jours, bonne tenue, bon ampérage permettant des résistances basses. NKon est vraiment un fournisseur incontournable avec des prix très compétitifs !

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