Test 2:

The same test was repeated using a

Fluke 80i-110s AC/DC Current Probe

in ‘High Current’ mode.

Results:

The power at the first voltage and current intercept was around 500 Watts.
The current peaked at over 100 Amps.

(Happily, it is only for about 50 microseconds.)

22.4. Miscellaneous

When the internal fan (the one that is on the module itself) is turned on, a fan icon will be displayed.

Minimum battery voltage: 500mV
