• Isolation -- we need to measure millivolts on cells more than 300V apart
• Measure cell voltage with 10mV (?) precision
• Survive cell voltages as low as 1.5V -- under acceleration cells may sag to half their normal voltage.
• Measure bypass energy. If we can count amp-hours bypassed then we can more easily write algorithms that predict what to do based on past behaviour.
