Optimize your time on the water with the Pro-Guide 3 Bank On-Board Battery Charger (PGC-21236)—a premium, marine-grade charging system engineered for anglers and boaters who demand reliable, efficient power management. Designed with three independent charging banks and a 30-amp total output, this onboard charger delivers precise, simultaneous charging for (1) 12V battery, (1) selectable 12V/16V battery, and (1) 36V battery system, making it ideal for complex trolling motor and accessory setups.

Built with advanced microprocessor-controlled smart charging technology, the PGC-21236 automatically detects battery voltage and condition, then adjusts charging modes to deliver the optimal charge cycle. This helps extend battery life, improve performance, and reduce downtime. Whether you're using AGM, flooded lead-acid, or compatible marine batteries, the charger ensures consistent, safe, and efficient charging every time.

The rugged, waterproof, and vibration-resistant housing is specifically designed to withstand harsh marine environments, including exposure to water, salt, and extreme temperatures. Its compact onboard design allows for permanent installation, eliminating the hassle of removing batteries for charging and ensuring your system is always ready to go.

Safety is a top priority with built-in protections against overcharging, reverse polarity, short circuits, and overheating, giving you peace of mind during every charge cycle. LED indicators provide clear, real-time charging status for each bank, so you can easily monitor performance at a glance.

Perfect for serious anglers running multi-battery trolling motor systems or boats with diverse power needs, the Pro-Guide PGC-21236 3 Bank Battery Charger delivers dependable, high-efficiency charging that keeps you on the water longer.

Core Technology & Performance

• Multi-Voltage Output: Unlike standard chargers, the PGC-21236 provides three distinct charging profiles across its banks: one 12V bank, one 12V/16V selectable bank, and one 36V bank.

• Intelligent Multi-Stage Charging: Each bank utilizes a micro-processor controlled 5-stage charging algorithm (Analyzing, Charging, Conditioning, Maintaining, and Storage) to maximize battery life and performance.

• Auto-Maintain & Recovery: The "Energy Saver" mode keeps batteries fully charged while in storage, and the unit is capable of recovering deeply discharged batteries that other chargers might reject.

• Built for Rigor: The charger is fully potted and waterproof (IP67 rated), providing protection against vibration, moisture, and saltwater corrosion in demanding marine environments.
