What is CAS?
The Cordless Alliance System is the first cross-manufacturer 18 Volt battery system on the market. Since its launch by Metabo in 2018, 50+ brands from a wide range of trades have joined.
All of the now more than 500 machines within the system are 100 % compatible — from classic power tools to specialized industrial products. For professionals, this means fewer chargers, lower costs, and maximum flexibility on the jobsite.
One battery
Fifty brands
Anyone who owns Rokamat batteries can also use machines from 50+ other brands — and vice versa. One jobsite, one battery fleet.

Advantages
Top technology
CAS uses Metabo battery technology — over 45 years of pursuing the vision of the “cordless jobsite”. Developed in Germany, it withstands the toughest use.
Complete freedom of movement
No cables in the way. Faster, more flexible, even in the tightest spaces — with no tripping hazards or hunting for power outlets.
Resource-efficient
One battery system for 500+ machines instead of 50 different chargers. Less material, less waste, less storage space.
Time- and cost-saving
No buying duplicate batteries for every brand. Charging time is jobsite time — the CAS system is designed for fast charging.
