Context/Background

• The system’s energy is supplied by a rechargeable onboard battery provided by an external supplier that is mechanically attached to a circuit board.
• The current version of that board fits only batteries of ONE specific supplier.

Product management has decided to reduce dependency of this specific supplier and to modify the circuit board.

Metric/Acceptance Criteria

• The circuit board (thus the system) shall be compatible with battery models from the five preferred battery suppliers.
• The system shall successfully operate with battery models from all these five suppliers without requiring any hardware modifications.
• The system shall pass functional tests with each battery model under standard operating conditions.
• The system’s performance, especially battery life, shall vary by less than 10% across the different battery models.
