Just when I thought I was ready to splash BIANKA for the season I made a disturbing discovery concerning one of the batteries in the 48 volt propulsion bank. The Dual Pro PS4 battery charger showed battery number four with a blinking green light where as all the others were steady after having been charged. This was a new development as for the past several weeks all the batteries had been charging normally on my visits. For some reason the charger thinks battery four is not yet fully charged. I disconnected the power from the charger to let the batteries sit overnight and make sure it would not fire up when I plugged the extension cord back on my return in the morning.
The next morning I went into the cockpit and threw the switch on the helm instrumentation panel that powers the individual battery meters. My suspicions were confirmed. Battery four is not being charged properly:
As you can see the bottom meter which is reading battery four is only 11.1 volts where the other three batteries are much closer to each other in voltage. So it looks like I will have to forget about launching the boat until I can investigate what it is going on with this battery. TO BE CONTINUED.
