Redarc SmartStart SBI Series

The Redarc SmartStart SBI series will help to manage your dual battery system. Only when the starting battery’s voltage reaches 13.2V will the auxiliary battery start charging, and if the system drops below 12.7V, the auxiliary battery disconnects, maintaining the main battery’s charge. With two models available, a 100 amp and a 200 amp, both have surge and spike protection, can be used with modern alternators, and are suitable if the two batteries are not the same (eg. cranking and deep cycle).
