Shell Seeker - Charging Upgrade

Our 1998 Broom 34 had the standard engine-to-battery charging setup when we bought her - 12volt/70amp alternator with built-in regulator/controller and an X-Split charge splitter (to split the alternator output between the engine start battery and the domestic batter bank).

With an electric fridge, relatively small domestic battery bank (2 x 120 amp/hour batteries) and no shore-power at our mooring, I calculated that we were in danger of damaging the batteries through discharging them too deeply. The solution I selected was to install an external, digital alternator controller and to add an instrument to monitor all the charge going int and out of the batteries.

I thought this would be an easy 2-3 day job - HA! It actually took me 10 full days work from start to finish. However, the results have been worth it.
