APPLICATIONS: The Link 20 provides instrumentation of two banks of
batteries. The Link 20 does not control an inverter/charger. For installations
involving a Freedom inverter/charger and two battery banks, the Link 2000

the Link 1000 is recommended. For instrumentation of a single battery bank
with no inverter/charger controls, the Link 10 is ideal.
