Blue Sea Systems continues to introduce a variety of different components to help improve a boat’s onboard electrical system. Among the latest is the BatteryLink waterproof charger suitable for flooded, AGM and TPPL batteries, a compact piece of kit that will be especially useful aboard smaller vessels. Measuring 6.7in-by-4.9in-by-2.1in, it incorporates an internal 65 amp ACR (Automatic Charging Relay) allowing two separate batteries to be charged simultaneously, connecting them when a DC charge above 13 volts is applied to either battery and disconnecting, or isolating them when there is no charging voltage or the load on a battery causes its voltage to drop below 12.75 volts. When connected to shore power it also functions as a 10 amp three-stage charger. Replacing what would be two separate components in most boats, this neat little unit will be especially well suited for use aboard small cruisers and weekender daysailers with two battery banks. Blue Sea Systems recommends bank sizes of 60 amp hours minimum to 120 amp hours maximum for optimum charging efficiency.
