The LinkPRO can measure currents up to 10,000 Amps. It selectively displays voltage, charge and discharge current, consumed amphours, remaining battery capacity and the time remaining of your battery bank. It is equipped with an internal programmable alarm relay, to run a generator when needed or to turn off devices when the battery voltage exceeds programmable boundaries. Note: The LinkPRO Battery Monitor is the direct replacement of XBM Battery Monitor with expanded features.
