Dual Pro PS4 Auto Charger with Three-Bank B.O.S.

The PS4 Auto and three-bank B.O.S. package is intended for a marine battery installation that needs both independent charging and balancing across a three-battery series pack. Its PS4 Auto charger handles four charging outputs. The separate B.O.S. module redistributes energy between the three connected batteries it monitors. That makes this different from the package containing a two-bank balancing unit.

AutoProfile technology allows the charger to select appropriate routines for supported lithium and AGM batteries. Charging is fully automatic and includes the manufacturer's onboard diagnostic features. The balancing unit employs the BSAP-24 selection process and a transfer capability listed at up to 7.5 amps. The systems work on complementary parts of battery care, rather than performing the same task twice.

This combination can be useful for a trolling motor bank that tends to become unevenly charged over repeated use. Waterproof construction and ignition protection are stated for the PS4 Auto charger. The battery arrangement must still be checked for chemistry, wiring and the correct number of series-connected batteries. See other onboard charger configurations for different power systems.
