Distributed-On-Demand™ Charging Technology

The ProMariner ProSport HD8 uses Distributed-On-Demand™ Charging Technology to manage charging power efficiently across two battery banks.

Instead of permanently dividing output equally between batteries, the charger automatically allocates available charging current based on each bank's needs.

For example, if one battery is nearly fully charged while another requires additional charging, the system can direct more of its available output to the battery that needs it.

Important: The ProSport HD8 delivers 8 amps total across two banks, not 8 amps per bank.

Automatic Multi-Stage Charging & Battery Maintenance

The ProSport HD8 uses digital charging technology to automatically manage the charging process.

Its charging and maintenance functions help:

• Recharge batteries after use
• Complete the charging process through controlled charging stages
• Monitor batteries after reaching a full charge
• Provide maintenance charging when needed
• Reduce unnecessary power consumption during storage

These features make the ProSport HD8 a convenient option for boat owners who want to maintain their batteries without constantly monitoring the charging process.
