Introduction Introduction Key Features Four Charging Stages Lithium Activation Introduction Introduction The Renogy REGO DC-DC Battery Chargers save on installation time than traditional chargers. The pioneering bidirectional charging technology not only provides the most effective way to charge your house batteries from the starter battery on the go but also recharges and maintains your starter battery when the house batteries are full.
Introduction Introduction Key Features Four Charging Stages Lithium Activation Four Charging Stages REGO 12V 60A DC-DC Battery Charger has a four-stage battery charging algorithm for a rapid, efficient battery charging. They include Bulk Charge, Boost Charge, Float Charge, and Equalization Charge.
Introduction Introduction Key Features Four Charging Stages Lithium Activation voltage set point. Once the battery is fully charged, there will be no more chemical reactions and all the charge current would turn into heat or gas. In this case, the DC-DC Battery Charger will reduce the voltage charge to smaller quantity, while lightly charging the battery. The purpose for this is to offset the power consumption while maintaining a full battery storage capacity.
