Prototype under test...
Charging starts with constant current up to approximately 80-85% and top-up is achieved with constant voltage until the pack reaches full charge and current drops to zero.

As can be seen, 12.6V charging voltage is right on target... :-)

Next stop: Two color LED to indicate charge and full charge status.
