The Ukrainian design bureau LOCKER has unveiled its latest innovation, the MZAK1 mobile workshop designed for charging drone batteries. This was announced in a press release from the bureau.
The workshop is based on a standard 20-foot container and is capable of charging batteries under field conditions. The dimensions of the container are 6 meters in length, 2.6 meters in width, and 2.59 meters in height, weighing approximately 5 tons.
Inside the container, there are cabinets for charging batteries with a capacity of 66,000 mAh, typically used for heavy drones like the "Vampir" and "Baba Yaga".
Additionally, it features a three-phase generator with a power output of 50 kW, providing voltages of 230 or 400 volts. The generator operates using 12 fuel canisters, each with a capacity of 20 liters, giving an overall fuel reserve of 240 liters. This setup allows for the simultaneous charging of 84 batteries.
There is also an external 380-volt socket, enabling power supply from an external source if the workshop is stationed at a permanent location.
The system can charge batteries ranging from 2S (composed of two cells) to 6S (composed of six cells).
The workshop features a table, tool storage, two internal 220-volt sockets, a first aid kit, an air conditioner, and a sleeping area. 
It is noteworthy that the workshop was developed from scratch in just two months.
Earlier, it was reported that a modular factory was established in the Czech Republic, producing UAVs in combat zones. This factory is also built using shipping containers and is capable of 3D printing drones.
