The Rolls deep cycle flooded battery bank is heart of your off-grid or backup power system. Combine the battery bank with our battery cables, inverters, controls, and solar modules for a complete solution.
The Rolls Batteries, made by the Surrette Battery Company in Canada, are a high performance flooded deep cycle battery designed to provide years of service. The 5000 Series of batteries are a good choice for medium and large sized battery banks for your solar or backup power system. The 4V, 6V, and 8V Batteries come in a wide range of amp hour capacities to allow you to design the right sized battery bank for your application. They can be wired in series to increase the voltage to 12/24/or 48 Volt and also wired in parallel to increase the amp hour capacity of the battery bank. We recommend no more than 3 or 4 strings of batteries in parallel. The 5000 Series of batteries feature a dual container construction to act as secondary containment for the acid and to protect the batteries from physical damage.
Cycle Life: 3200 Cycles at 50% Depth of Discharge
