■ The SP1470 series has been specifically designed to reliably withstand the very high and low
temperatures experienced in street cabinets.
■ The battery management system enhances the life of the batteries by controlling the charging
current and avoiding deep discharge.
■ Regular battery test loading monitors battery health without risk of system failure.
