The fully-automatic battery charger uses an intelligent, multi-stage charging program that can be set to a wide variety of battery types using easy, one-button programming and features a full suite of electronic protections.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThis system is ideal for caravans, campervans, motorhomes or boats, where the alternator charging can be shared between the starter and leisure batteries while the engine is running, then the leisure battery can be kept topped up from solar power while the vehicle is parked. By combining two chargers into one unit the set-up and operation are made simple, allowing you to easily share an existing charging source between two batteries or battery banks and utilise solar power to extend your off-grid runtime.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eKey Features:\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\r\n\r\n\u003cul class=\"bullet\"\u003e\r\n\t\u003cli\u003e\r\n\t\u003cp\u003e\u003cstrong\u003ePowerful MPPT solar charge controller with overload protection:\u003c\/strong\u003e compatible with solar panel(s) up to 40A at 16-25V, automatically activates when there is no battery-to-battery charging.\u003c\/p\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\u003cp\u003e\u003cstrong\u003eFully-automatic, high-frequency, multi-stage charging:\u003c\/strong\u003e ensures the battery is charged safely and quickly.
