Observe → D1 (STAT) ON

Open JP4 (set fast charge)

Measure → I(J2(VBAT)) = 2A ± 200mA

Observe → D1 (STAT) ON

Open 2-3 of JP1 (external TS)

Measure → I(J2(VBAT)) = 0A ± 100mA

Observe → D1 (STAT) BLINK

Connect 2-3 of JP1 (Internal TS)

Measure → I(J2(VBAT)) = 2A ± 200mA

Observe → D1 (STAT) ON

5. Charge Voltage Regulation

Observe → I(J2(VBAT)) decreases from 2A while V(J2(VBAT)) becomes constant.

6. Test Complete

Turn off the power supply and remove all connections from the unit under test (UUT).
