Power distribution board

The backbone of your power system.

Low-impedance power paths and a high-current copper structure that keep the rail from sagging even under sudden draw. This is not a connection plate.

What matters

Multiple high-current outputs

Feeds motor driver, control board and auxiliary systems from one battery, on one board, without them disturbing each other.

Buffer capacitance

An on-board capacitor bank that steps in before the battery rail sags on launch or on a sudden throttle command.

Thermally optimised copper

Power planes are sized to spread the heat that high current produces. They do not build hot spots.

Field-durable mechanics

Mounting and connector layout laid out to keep working under vibration, dust and heat.

Questions about this product

What exactly does the power distribution board do?
It takes a single high-current line from the battery and distributes it across the consumers in the system with low loss and in balance. Its buffer capacitance steps in before the battery rail sags on a sudden draw, and the copper power planes are sized to spread the heat that high current produces without creating a hot spot. In short, it is not a connection plate — it is the backbone of the power system.
Do I have to buy both products together?
No. The two work independently. If your system has a single motor and no distribution need, the motor driver alone may be enough; if you feed several consumers from one battery, the power distribution board alone may be. Tell us your application and we will work out together which one you need.
Do you design boards for a specific application?
Yes. On most projects one of our existing boards fits with a small adaptation on the connector and mounting side. Where it does not, we design from scratch — schematic, layout, power plane sizing and thermal check included.
What vehicles and platforms are the boards used in?
Electric race cars, unmanned aerial vehicles, underwater systems, autonomous ground platforms, and industrial drives and test benches. What they share is having to manage high current in a limited volume and in demanding conditions.
