Waterproof chargers are designed to charge one battery on each of their outputs. They are suitable for small fishing boats like bass boats or center console boats. They are for charging batteries that are not being used while they are charging. Dry-mount chargers are for boats with a shore power connection and AC distribution/breaker panels. They need to be mounted in a dry area where they will not get dripped on or sprayed with water. They can handle capacity batteries and/or charge batteries while they are under load. If you need advise on choosing the right charger, please contact our technical service at 1-800-307-6702 and we can help.

No. The waterproof chargers output 12 volts on each set of leads. With a 2 bank charger you can charge a 24v system by attaching a single set of leads to each 12v battery.
