Battery Charge #28

August 15, 2011:   This Ford Ranger Electric Vehicle drove 9 miles today.  It arrived home with a state of charge of 60% or 152.8 Volts.  Started charge PFC 30 Manzanita Micro Charger at 7:15 PM:
Set charger at 28 Amps.
38 minutes later I returned to see the charger cutting back current to 20 Amps.  Maximum pack voltage was 174.4V.
9 minutes later the the charger cut back to 17 Amps. 
At that time, I changed the PFC 30 charger timer from 1 PM setting to one click further to 30 minutes total because I observe the charger cutting off too early before equlaization occurs with lower voltage batteries.
Set at 12 Amps, 18 minutes later, the blue light started blinking and timer started.  30 minutes later, the charger shut off.  Final voltages were similar to charge #27. 
Charge time was 1 hour 36 minutes.
