1. A battery monitoring system, comprising:
- a self-contained measurement device configured to mount to a battery cell, wherein the self-contained measurement device comprises;
a first lead configured to couple to a positive terminal of the battery cell and a second lead configured to couple to a negative terminal of the battery cell to enable the self-contained measurement device to operate using first electrical power received from the battery cell via the positive terminal and the negative terminal while the battery cell outputs second electrical power used to operate a battery management unit;
a sensor configured to monitor an operational parameter of the battery cell; and
a communication module configured to output a signal indicative of the operational parameter to the battery management unit via the first lead and the second lead.
