Meet the ProMariner ProSport HD Gen4 8 Amp Battery Charger—your compact, high-performance solution for 12/24V vessels. This 2-bank charger stuffs true constant-current charging into a lightweight, rugged package that’s built to handle harsh marine environments while delivering precise, fast charging every time.
Smart, efficient charging that saves energy
-
Microprocessor and software controlled charging for fast, precise charging. 100% of all available charging amps are utilized by distributing unused amps to any one or combination of batteries as needed.
-
Five-stage automatic charging analyzes, charges, conditions, auto maintains, and reconditions batteries monthly during storage to extend life and performance.
- Automatic monitoring and maintenance only when needed minimizes AC power consumption while keeping batteries at peak state of charge.
Industry-leading cooling and design
-
Tri-surface heatsink design delivers optimal cooling and maintains true rated current during operation, while the unit remains up to 40% lighter than epoxy-filled chargers.
-
Two-charge-mode operation provides consistent, reliable current to keep both banks performing at their best.
- Harsh-environment rugged construction with industrial-grade jacketed DC/AC power cables and reinforced strain reliefs.
Clear status, safe operation, and broad compatibility
-
LED indicators include a fuel-gage style completion readout and a four-color multi-stage status bar showing Charge Mode, System Check OK, Battery Status, and Battery Type.
-
Protection features include dual inline waterproof fuses, reverse polarity, over-temperature, over-current, over-voltage, and ignition protection.
-
Battery compatibility supports Group 24–31 Flooded, AGM, Gel, and HP AGM configurations, enabling versatile use across common marine batteries.
- Certified and compliant: Marine UL 1236, CEC and DOE listed, and FCC Class B.
