Power that
flows.

Superstream builds modular, connected battery systems for electric vehicles and machines in motion — designed, engineered and programmed end-to-end in Finland.

Superstream modular battery module
Scroll

Batteries have been black boxes. Heavy, silent, sealed away.

We think energy should move with you — modular, intelligent and built to be seen.

01 — The module

One module.
4.99 kWh of flow.

A rugged, sealed enclosure with an integrated handle and high-current connectors. Everything you need, nothing you don't.

02 — The system

Stack it.
Scale without limits.

Modules link side by side into one system — grow capacity with your needs, swap a module in seconds.

03 — The engineering

Built to be seen.

High-density cylindrical cells, laser-welded interconnects and a thermally optimised layout — mechanical and PCB design done fully in-house.

04 — The intelligence

Live telemetry,
built in.

An onboard display and connected BMS stream charge, voltage and health in real time — on the device and in your applications.

By the numbers

Compact outside.
Serious inside.

Two models, one platform — the same technology and footprint, in your choice of voltage and capacity.

Mechanical & PCB design

From enclosure to copper trace — our hardware is designed as one system, optimised for vibration, thermals and serviceability.

Embedded software

Battery management, safety and control firmware written in-house — deterministic, tested and field-updatable.

Connected applications

Every module speaks to the internet. Fleet views, live telemetry and integrations for the systems you already run.
