CALB L221N113 3.7 volt 113ah lithium nmc cells

LYTH Battery – The Best Partner for your Lithium Battery Solution & High Performance

The ternary material (NMC) is actually a synthesis of the advantages of LiCoO2、LiNiO2 and LiMnO2 materials. because of the obvious synergistic effect between Ni、Co and Mn, the properties of the NMC are better than that of a single set of layered cathode materials, which is considered to be one of the most promising new cathode materials.

CE, UL, MSDS, and UN38.3 have been approved. (L221N113)3.7V 113Ah NMC battery cells were already passed all of the safety tests(overcharge, over-discharge, over-temperature, short circuit, drop, crush tests, etc).
