ECO-WORTHY 20A Dual-cell solar charge controller takes over the charging process of 2 batteries with priority to battery 1#. When charging conditions allow, the controller will charge battery 1# first and then start charging battery 2# after battery 1# exceeds the set proportion of electric capacity (70% by default, 10% - 90% adjustable) until the set proportion of electric capacity of battery 2# is achieved. After that, the controller will charge both batteries by turns.
