    Reserve Capacity - Another Battery Question

    I have 2 12-volt trolling batteries for my 24 volt Ultrex. Each battery has 175 minutes reserve capacity. Is my Reserve Capacity 175 minutes or 350 minutes? Thanks.

    I'm just guessing, but I'd say 175, since you're using them in series for 24 volts.

    175. Series doubles voltage. Parallel doubles capacity.

    We have had this discussion before and some will say capacity is slightly increased but I am with the majority...capacity stays the same and voltage is doubled when two 12V batteries are in a 24V series connection

    You have more run time in series,as the % of voltage loss is half that of a 12v system.
