Powerful Battery Tech: Power Without Limits

Watermeln sets the standard for mobile power supply. Our battery systems are built for heavy-duty performance: from construction sites and festivals to the maritime sector. We deliver guaranteed continuity, whether you are working fully off-grid or need to reinforce your grid connection.

Smart Battery Swap: Zero waiting time

Don't have time for long charging sessions? With our unique swappable design, you can exchange an empty unit for a full one within 10 minutes. This keeps your project moving constantly, without any dependence on local charging infrastructure.

WM-DC5: Smart modular setup

What truly sets this system apart is its unique modular design: you only get and pay for exactly what you need. Because the AC box and DC CCS charging box are supplied externally, they stay on-site and do not need to be transported back and forth with every battery swap—saving you unnecessary logistics and costs.

Output variants:

AC 100 kW & 240 kW

DC CCS 2 sockets 120 kW

WM-AC5: The solution to grid congestion

In addition to our swap proposition, the WM-AC5 is exceptionally well-suited for grid-connected projects. Dealing with grid congestion or limited capacity? The battery acts as a powerful buffer (peak shaving), ensuring you have the required power without overloading your grid connection.
