SBS-EquaLink Battery Monitoring System

Easy to setup and configure, EquaLink is a complete Battery Management System with active voltage balancing.

EquaLink is an Ethernet-based battery management system that monitors the voltage, internal resistance, and temperature of each battery in a stationary, telecom or UPS battery system. Through a patented balancing process, EquaLink actively regulates the float charging current of each battery, ensuring all batteries charge at their optimal voltage. This system is designed for many battery applications including lead acid (flooded/wet, VRLA, gel, AGM, etc.) as well as nickel cadmium (Ni-Cd) and nickel metal hydride (NiMH).
