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 4000 Series of batteries are a good choice for small and medium sized battery banks for your solar or backup power system. The L-16 sized, 6 Volt batteries come in capacities of 460, 530, or 600 amp hours (100 hour rate). 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 strings of batteries in parallel. If you need higher capacity, see the 5000 Series of 2V, 4V, 6V, or 8V larger batteries.
