Charging lithium batteries with solar
I've got lithium camera batteries and a lithium jump starter battery pack. All charge via 12v auto circuits, i.e. they have their own chargers, they aren't bare batteries. They all work up to at least...

Why can't your PWM controller sense anyting?
If the battery voltage is low
(under 12.5V - this test will not work if the SunGuard is regulating
in PWM), then measure the solar voltage and battery
voltage close to the SunGuard. If the voltages are within a few
tenths of volts, the array is charging the battery. If the solar
voltage is close to 20 volts and the battery voltage is low, the
controller is not charging the battery and may be damaged.
I get it there is something between the batter and the controller:S
