4th Battery for 272 Sailfish

[grady33]

Anyone ever add a 4th Battery to 272 Sailfish? If so, where exactly did you put the battery. Was thinking of adding one to power underwater lights at night and extra juice for electronics.

My 1998 272 has a 4 battery configuration installed by the dealer.
All 4 batts sit on a shelf under the rear seat.
The 2 engine batts have individual switches. the 2 house batts are served by a Perko 2 batt switch. The charger is a 3 bank, 10,5,5. The 2 5s each serve the starting batts, the 10 serves the house batts through the selector switch.
Hope this helps.
