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.
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-art. The 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.
Technicality |Precise Handcrafting.
The CMEC batteries are simple and powerful – have a low internal resistance, high output, and a long lifespan. We don’t secretly keep the way how they are built! Every cell in a battery pack comes from the same lot, rank, and we use original techniques to ensure maximum quality and performances – learn more >>>
In short, our advantages: Flexibility, and react to the market | Custom configuration on-demand | In-house manufacturing & rapid prototyping, using only top quality materials | Lower cost when producing in low volumes.
