   * **theory** tells us that I=V/R.  This means that current will be the ([alternator voltage] - [resting voltage of the battery] / total resistance in the circuit.   We almost always know the voltage part but few know the resistance of their charging circuit.  After an observation we can back into that value.
   * an **often-repeated (and wrong)** answer is 200A, because the BMS cuts off at 1C.

     * current at middling states of charge averages ~0.2C, or 40A.
     * current at high states of charge((upper knee)) averages ~0.1C, or 20A.

 There is a good chance DC-DC will be required here to stay at our 50A continuous max.  But there is little harm in turning the key to take quick measurements since our wiring is fused at 75A.  If current is as high as predicted the fuse pops and we start thinking about a DC-DC.
