Battery Charge #4

July 13, 2011:

Re- Installed PFC 30 charger tonight:

Started charging and ramped to 29 Amps (initial voltage 150 VDC).  At about 30 minutes in, the yellow charger light was blinking without the blue (161 Volts).  This was indicating charger was getting warm.  Therefore, I turned it down to 25 Amps.  Yellow light went off.  I charged for another 20 minutes at 25 Amps, then turned back the amps to zero.  I decided to stop charging at 166 VDC (warm).
