Battery Pack Requirement Sheet Template (PDF + Word Download)

This requirement sheet is a template. The figures below are example values, chosen to show how each field is filled in. Download the PDF or the Word file, replace the numbers with yours, and send it with your drawing.

How to use this sheet

A blank field means undecided, not "no requirement". Every blank becomes a supplier default, and that default turns into your specification once you accept the quote. Fill in what you know, then send it rather than leaving gaps to be interpreted.

Keep the structure and the units. Change the numbers to yours. Do not drop units, and do not write "per national standard" where a number belongs.

The first four sections move the price. The last four decide the risk. Sections 1 to 4 tell a supplier what to build. Sections 5 to 8 decide whether the units come back from the field during the warranty.

1 · Commercial

2 · Application

3 · Cells and configuration

4 · Electrical

5 · Protection and monitoring

6 · Interfaces

7 · Mechanical and environment

8 · Certification

Derived values worth checking before you send it

The 108 Wh figure crosses the 100 Wh line that separates the lighter shipping regime from the full one. Add another cell and the pack moves into a different transport class.

Seven fields left to decide

1. Life requirement: calendar life, cycle count, retained capacity at end of warranty

2. Maximum instantaneous discharge current, and how long it lasts

3. Size envelope in mm, or the internal dimensions of the enclosure you plan to reuse

4. Operation mode: pick one of the three stated above

5. Fuel gauge output: add bus lanes for I2C or SMBUS, or voltage indication only

6. Charging behavior below 0 °C: cutoff temperature and behavior at -10 °C

7. Certification list, including transport
