SW5 is definitely OFF (Up) for Lithium battery
SW3 and SW4 are therefore set to ON (Down) to disregard float voltage
SW2 and SW1 set the bulk or constant voltage for your battery, so if you are needing to set 14.4 volts, then yes, SW1 would be OFF (Up) and SW2 would be ON (Down)
Wow! I don’t like DIP switches where ON is down, and I really don’t like Renogy’s instructions for installing the charger. :W :B
I can understand why it might be hard to understand. :h
