CMEC Li-ion battery packs are engineered to power the electric propelled unmanned aerial vehicles (UAVs) commonly known as a drone. The configurations on demand can start from 4s3p to 12s12p, customized on the aircraft specs for a maximum yield and long-range flight.

Inside the battery pack.

The Sanyo NCR18650GA are top-grade cylindrical lithium-ion battery cells with specific energy more than 250 Wh/kg, and energy density about 700Wh/L. They are produced by Panasonic at factories in Hyogo and Osaka, Japan ジャパン (Panasonic Corporation bought the Sanyo Energy Co. in 2011).

パナソニック NCR20700B is currently 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 NCR20700B is less than 20mΩ. The bigger cells (20,3mm in diameter and 70,3mm long) enabled CMEC to optimize volumetric energy density into a new pack.

Another cell type, NCR20700A, is capable of a continuous discharge of 30A with a staggering peak potential of 45A. Battery packs in large configurations, engineered with this kind of cells can instantly deliver hundreds of ampere and will help for example, in a fast take-off of the VTOLs type unmanned aircraft, or electric missile.

Sanyo-Panasonic NCR18650GA Li-ion battery cells

These all cells incorporate several thermal, chemical and mechanical elements that contribute to their safety in the CMEC battery packs. Lithium Nickel Cobalt Aluminum Oxide (LiNi0.8Co0.15Al0.05O2) is a highly thermally stable cathode material used lithium-ion batteries. Doping the lithium nickel cobalt oxide with aluminum both stabilizes it’s thermal and charge transfer resistance.


Serial and Parallel Configurations

Safe, higher performing battery design – many cylindrical cells connected in series and parallel, the best solution state-of-the-artThe Tesla Model S all-electric car has about seven thousand of NCR18650 cells inside the battery housing, these are split into many packages. CMIUTA Electric Company uses almost the same recipe, in smaller-scale and specially optimized for large unmanned aircraft used on endurance flight or heavy payloads.
