Hi everyone.
I have a K&W BC-20 charger in my 72V Electric Geo Metro runabout.

Lately, the charger only goes at full amperage very briefly, maybe ten minutes or so (this is with the batteries needing a charge.)
After that, the amperage drops down to fairly low, as though it's finishing off the charge.

Both the voltage and amperage pots are turned all the way up, and it has the correct resistor installed to select for a 72V system.

It is used batteries in the car, and I DON"T have INDIVIDUAL battery monitoring, just one pack voltmeter. When I check the batteries individually with my multimeter, none of them are that far off from each other.

Any idea what's going on here?

Thanks in advance.
