Discover cordless machines powered by CAS
Cordless Alliance System (CAS) is a cross-manufacturer battery pack system of leading power tool brands, initiated by Metabo. What does it mean that PROMOTECH belongs to CAS? For end-user it means that the same battery and charger can be used to power over 300 machines from more than 40 brands.

Inter-brand compatibility
Thanks to the multi-brand battery system, one benefits from maximum flexibility and compatibility. Machine operators can conveniently interchange batteries and chargers among different power tools, regardless of the brand, as long as they are part of the CAS alliance. Everything fits everything: machines, batteries, and chargers.

Cut the cord – keep the power
CAS enables a variety of professional applications in battery technology, including standard tasks and special assignments in metalworking, construction, plumbing, woodworking, and other industries. The focus, however, is on 18V – the most important application range for professional users. LiHD – the most powerful battery pack technology in the world is 100% CAS compatible. The technology covers a performance range of 400 to 3200W and thus, offers enough power even for very energy-intense applications.
Being the CAS member PROMOTECH implements battery pack system in various products such as:
| Welding and cutting tractors | Mag drills | Bevellers |
|---|---|---|
| GECKO Battery 2 >> Mini SPIDER Battery >> SCORPIO Battery >> DRAGON Battery >> MANTIS Battery >> | PRO-36 Battery >> PRO-36PM Battery >> PRO-36R Battery >> | BM-6 Battery>> PRO-2 PB >> PRO-5 PB >> |

LiHD (High Density Lithium Ion) battery packs used in PROMOTECH machines feature:
| MORE POWER | than standard Lithium batteries thanks to busbars and larger contacts capable of handling high currents. 3x better conductivity is achieved thanks to cell connectors made of a specialized copper alloy |
| LONGER RUN TIME | than standard Lithium batteries thanks to more active material in the new 21700 cells and use of higher-quality materials (silver and copper) |
| LONGER SERVICE LIFE AND EXTREMELY ROBUST DESIGN | than standard Lithium batteries thanks optimal protection against internal contamination through complete grouting and full protective coating on the electronic components, as well as an optimal seal on the top structure. – The cells are protected by a rubber buffer and exterior rubber coating on the battery pack provides secure, non-slip stability and protects against impacts. – The battery requires less frequent charging thanks to more usable cell energy |
| INCREASED PRODUCTIVITY | – Patented Air Cooled charging technology enables the hot battery to be placed on the charger immediately – The charger’s built-in Air-cooled system quickly cools the battery as the pack begins its charging cycle |
| EXTENDED THE LIFESPAN | – A permanent Electronic Single Cell Protection when charging, which is designed to extend the lifespan of the battery – Because each cell in the pack charges and discharges evenly |

One battery, many possibilities
PROMOTECH cordless machines represent a comprehensive solution for professionals, offering flexibility, performance, and long-term value through its unique inter-brand compatibility.
There is no doubt that the demand for battery-operated tools will increase among professionals in the near future. Applications that were previously reserved for the most powerful mains-powered machines are now possible without mains power. Providing higher safety and comfort of use.

Greater flexibility and portability
Cordless machines allow you to maneuver and move about freely without the hazard of tripping or tangling a cord. They are well-suited for the outdoor work in remote areas, where no power supply is available and battery-operated tools are more convenient to operate.
With dual batteries one can easy swab batteries and do your work without interruption. While you are using the tool, the other battery is being charged. Further developments in battery technology will facilitate even longer operating times and higher loads being possible with cordless power tools.

Cost savings
By using the same set of batteries and chargers for different tools, users can save on purchasing batteries and chargers dedicated for each tool or each brand.

Future-proof investment
High-quality and high-performance batteries ensure prolonged operation even in challenging conditions. Guaranteed compatibility with future products introduced to the market, makes the CAS system a long-term investment.
Everything fits everything: machines, batteries, and chargers from 40 respected power tool manufacturers, making operating with PROMOTECH machines even more user-friendly.
