Pack requirements Estimates are welcome

Fill in what you know. Leave the rest blank. These are targets for us to review, not confirmed pack ratings.

Voltage and current

Nominal voltage is the target operating voltage. Maximum voltage is the highest your equipment can accept. Peak current is a short burst, such as motor start-up.

Space and weight

Enter usable space inside the enclosure. We also need room for wiring, insulation and protection.

Runtime and priorities

Runtime depends on the load. An estimate of how the equipment will be used helps us review it.

Tell us what needs to fit

Use the requirements form above for voltage, current, enclosure space and weight. Early estimates are fine.

Choose your main priority. If space is fixed, say so. If a larger pack is acceptable for more runtime, we can review that option with you.
