ProMariner makes excellent chargers. The ProSport HD series is their 4th generation of chargers with full digital circuitry and advanced charging modes. You can select the battery chemistry via the pushbutton on the front, and from there it's fully automatic. It's storage recondition mode and Auto Maintain mode are safe for indefinite periods of time.
Distributed Charging means that unlike lower-quality chargers that will do maximum 10 amps down each of the 2 outputs, this charger will route all the power to the battery that's low. For example, if battery 1 is charged but battery 2 is drained, the charger will route 1-2 amps to battery 1 and 18-19 amps to battery 2. This is a significant advantage with multi-battery setups.
If you only have one battery, you can still use this charger! Just connect both positive and both ground leads to the same battery and the charger will operate normally without losing any features.
