The Dometic PLB40 has powerful, integrated Lithium Iron Phosphate (LiFePO4) battery cells, providing an energy supply of 40Ah/512 Wh. Ideal for powered coolers and other 12 V appliances while on adventures, the PLB40 provides a weekend of power or longer for a Dometic CFX on a single charge. The integrated DC-DC charger offers three convenient ways to charge via: the vehicle's 12 V DC socket, a solar panel or AC home power. The battery’s integrated Battery Management System protects the PLB40 from under-voltage, over-voltage, short circuiting and overheating for optimum charge time, performance and storage. With this power management system, the Dometic PLB40 has a cycle of life up to four times longer than more commonly used lithium ion batteries.
