Ensure your batteries are always ready for action with the Minn Kota On-Board Precision Charger MK-318 PCL 3-Bank × 6 AMP LI Optimized Charger (1833181) — a premium marine charging solution engineered for durability, performance, and optimized battery health. Designed for anglers, boaters, and outdoor enthusiasts who demand reliable power, this onboard charger delivers precise, multi-stage charging for a variety of 12 V battery types, including Lithium (LiFePO₄), AGM, gel, and flooded lead-acid batteries.
Built with advanced digital control and automatic charging technology, the MK-318 PCL intelligently adjusts the charge profile for each bank to maximize battery life and minimize charge time. Its three independent charging banks let you simultaneously charge multiple batteries with 6 amps per bank, ensuring balanced power across your system.
This rugged unit is engineered for marine conditions: waterproof, shock-resistant, and vibration-resistant — perfect for boats, fishing vessels, and other outdoor environments. LED indicators provide clear charge status at a glance, and automatic temperature and low-line voltage compensation keep the charger performing consistently in variable conditions.

| Feature | Specification |
| Banks | 3 |
| Output Per Bank | 6 Amps |
| Total Output | 18 Amps |
| Charge Profile | Multi-Stage (Bulk, Absorption, Maintenance) |
| Battery Types | Lithium (LiFePO4), AGM, Gel, Flooded Lead-Acid |
| Dimensions | 9-1/4" L x 9-1/2" W x 3" H |
The "6-Amp" Advantage: While lower than the 10-amp PCL models, the 6-amp output is gentler on battery health over the long term and is perfect for overnight charging when you aren't in a "rapid-recharge" hurry.
True Lithium Profile: Specifically designed to reach the higher voltage levels required to fully top off Lithium (LiFePO4) batteries and balance their internal cells.
Zero Spark Technology: Protects against accidental reverse polarity connections, ensuring you don't fry your batteries or the charger if you mix up the leads.
Automatic Temperature Compensation: The charger senses ambient temperature changes and adjusts the voltage output to prevent overcharging in the heat or undercharging in the cold.
