As expected, the highest quality! I ordered 2 single, they were delivered as a pack in a practical battery box, really good! The batteries find their place in the ThruNite TN12, therefore expect the raw power of this quality cells! In ThruNite MCC-2 charger, this began to load with 3.7 V, rising slowly but surely to 4.2 V peak ... !!!
Addendum: The TN12 was (1050 lumens) tested between 800 lumens and the brightest mode about 30 minutes, the battery showed in the charging station even 4.1 V to. Madness battery! Absolute recommendation !!!
