Abstract
A battery pack provided with a current cut-off device connected in series with batteries, a tamper detector to detect tampering and issue a tamper signal, and a control circuit connected to the tamper detector. If the tamper detector detects tampering with the battery pack, the control circuit switches the current cut-off device off to shut off current to the batteries, or it issues a tamper signal.
