Commercial Battery Conditioning and Monitoring

Take control of your battery power system by monitoring your battery State of Charge and State of Health with HDM’s Battery Fuel Gauge. HDM’s Battery Equalizer maintains an equal voltage across series-connected batteries.

Battery Equalizer - EQ48-12

HDM’s EQ48-12 Battery Equalizer is a bi-directional circuit that balances the voltage between four or more individual batteries connected in series during charge, discharge, and idle periods. EQ48-12 prevents severe under and over voltage, common in series connections, which can compromise the performance, reliability, and life of your battery system. Equalized batteries are able to receive a full, clean charge, increasing battery pack power, capacity, and life, therefore supporting your mission much better.

  • Available in 24V/12V, 48V/12V, & 48V/24V configurations

  • Up to 5ADC maximum equalization pulse current

  • Advanced bi-directional circuitry provides automatic equalization during charge, discharge, or idling

  • Utilizes patented passive energy transfer technology

  • Ideal for high voltage systems in series-connected string

  • LED status indicator with battery diagnostic scheme

  • Protection against under/over voltage and over current conditions

  • Easy installation and maintenance-free operation

  • Meets IP65 ingress protection requirements

Battery Equalizer - EQ48-24

HDM’s EQ48-24 Battery Equalizer is a bi-directional circuit that balances the voltage between four or more individual batteries connected in series during charge, discharge, and idle periods. EQ48-24 prevents severe under and over voltage, common in series connections, which can compromise the performance, reliability, and life of your battery system. Equalized batteries are able to receive a full, clean charge, increasing battery pack power, capacity, and life, therefore supporting your mission much better.

Battery Separator - BAS200-12D

HDM’s BAS200-12 Battery Separator is your intelligent charge priority system at sea and on the road.

This product uses a solenoid priority system to control multi-bank charging, assist in on-demand engine starting, and protect respective batteries from the excessive drain. Compact and economical, the BAS Series battery separator is the ultimate solution to your multi- bank battery systems.

BAS200-12 Battery Separator will ensure the Main bank is fully charged before charging the Auxiliary bank. BAS200-12 Battery Separator will automatically deactivate during low voltage conditions to prevent the main battery from becoming over drained. Auxiliary Start feature combines the two banks (Main + Auxiliary) for the additional engine starting boost.

  • Available up to 500ADC continuous 12VDC

  • Uni or bi-directional configuration

  • Automatic under/over voltage protection

  • Auxiliary start feature - combines the main and auxiliary bank

  • Voltage transient protection Ignition-proof construction

  • Available with IP65 option
