I will be switching out batteries this week to 4 Trogan T-105's and will go from there,
be sure to set batt type flooded. you can add a coin cell battery so the controller remembers your setting if you ever disconnect the controller from your batteries.
If the default settings don't suit your needs, program what ya want with the 'other' type.
I like to monitor PV voltage, when it exceeds batt voltage, ya know that the panel can make more power than needed and PWM is limiting power to the batt to maintain batt voltage.
