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).

  • Patented voltage balancing process
  • Pinpoints poorly performing cells
  • Regulates charging (prevents overcharging and undercharging)
  • Advanced warning system
  • Remote or local log in
  • Email and SMS text alerts
  • Detailed trend and graph analysis software
  • Downloadable battery history (CSV file format)
  • SNMP, Modbus and DNP3 communication
  • Compatible with batteries 2V to 16V
  • Thermal runaway prevention
  • Listed to UL 60950 standards
  • Prevents unexpected battery failure
  • Eliminates undercharge and overcharge which lead to almost all battery problems
  • Increased battery capacity
  • Extends battery service life
  • Easy access to battery data via web browser
  • Automate data collection for NERC requirement
