Battery Packs for UAVs

The bare-bones NCA battery cells made by Panasonic at the former Sanyo factory in Japan.

NCR18650GA (NCR18650G-H0ExA) has the specific energy of more than 250 Wh/kg and energy density of about 700Wh/L. The cell specs help us to build highly most efficient and extremely balanced battery packs.
NCR20700B (NCR20700B-H00Bx) is so far the most cost-effective cell created by the Japanese, offering an average of 30% more performance as opposed to its NCR18650GA counterpart while sacrificing just under a 10% increase in size! The internal resistance of this cell is less than 20mΩ. The bigger cells (20,3mm in diameter and 70,3mm long) enabled CMIUTA Electric Co. to optimize volumetric energy density into a new battery module.
NCR20700A  (NCR20700A-H00xA) is capable of a continuous discharge of 30 amps, with a staggering peak potential of up to 45 amps, in certain conditions (with an active cooling system).

These all cells incorporate several electrochemical elements that contribute to their safety. LiNi0.8Co0.15Al0.05O2 (NCA) is a highly thermally stable cathode material used in lithium-ion batteries. Doping the lithium nickel cobalt oxide with aluminum both stabilizes it’s thermal and charge transfer resistance.
