I set it up and ran it overnight. One of the channels read "END" after charging. The discharge and charge numbers were 3707mah and 5090 mah. I set the "CAPACITY CUTOFF" to 7500 mah. It never reached 7500 mah, so, why did it stop charging and end? And, if it had reached 7500 mah charge, the display would read, "CAPA". Another channel read, "FULL CHG". I was unable to read the charge and discharge capacity after getting this reading. The instruction sheet is poor and has errors.
I did think of a reason that it will stop discharging. If the voltage drops down to 6.2 volts (where I programmed it), that would end the cycle or cycles. Maybe it reads "CAPA" if it can charge to 7500 mah and not exceed 10 volts? I will monitor it closely to learn more.
