The Shift to Electric: Performance Meets Responsibility
The marine industry is undergoing a quiet, powerful revolution. As boating enthusiasts and commercial operators prioritize sustainability and seek quieter, maintenance-free alternatives, electric outboard motors are quickly becoming the propulsion of choice. This shift, however, presents a critical challenge: Power Management.
A high-performance electric outboard motor demands a sophisticated charging solution—one that can deliver the required power (42V 5A and 10A in this case) efficiently, safely, and repeatedly, often in harsh marine environments.
At Henryuan, we understand that when your motor is running silent, your power supply should be too. Our commitment is to ensure the power management is as reliable as the motor itself. The image above, shared by one of our valued European partners, perfectly captures this commitment: a sleek, modern electric outboard drawing essential power from a robust, fully certified Henryuan 42V Lithium battery charger.

Engineered for Excellence: The Henryuan Difference
Henryuan battery chargers are not entry-level commodities. They are precision instruments designed for the mid-to-high-end market, where failure is not an option.
1. Unwavering Quality: Power Delivery You Can Trust
For marine and high-draw applications, charging stability is paramount. Our 42V lithium battery chargers utilize an advanced CC/CV (Constant Current/Constant Voltage) and trickle charging algorithm, specifically tuned for 10S (10-series) Lithium-ion battery packs, the configuration for many electric marine batteries.
Precision Charging: We guarantee an output voltage tolerance tighter than +/- 0.2V of the target 42V peak, ensuring the battery reaches its optimal charge level without stress.
Thermal Management: Our chargers are designed to dissipate heat efficiently, minimizing energy loss and preventing thermal degradation of both the charger and the costly battery pack—a common vulnerability in lower-quality units.
Low Ripple, Clean Power: In sensitive marine electronics environments, high ripple current can cause system noise and data errors. Henryuan chargers are engineered for exceptionally low output ripple, providing clean, stable power that won't interfere with navigation systems or onboard communication.
2. Global Compliance: Ready for Any Port of Call
For manufacturers of electric outboards and their battery systems, navigating the complex web of international safety regulations is a major hurdle. Henryuan eliminates this challenge by ensuring comprehensive global certification from the design stage.
Our 42V charger series holds a full spectrum of globally recognized safety marks, making your final product instantly marketable across major continents:

North America: UL, cUL, FCC, ETL
Europe & UK: CE, GS, UKCA (LVD, EMC Directives)
Asia & Oceania: SAA, PSE, KC, CCC
By choosing Henryuan, you are not just buying a charger; you are buying market readiness. This level of certification guarantees that your electric outboard system meets the highest safety standards required by regulatory bodies worldwide, assuring end-users and simplifying your logistics chain.
3. Safety First: Protecting Your Investment

A lithium battery pack for a marine motor represents a significant investment. Henryuan chargers incorporate robust, multi-layer protection features to guarantee the longevity and safety of that investment:
Over-Voltage Protection (OVP): Essential for preventing permanent cell damage due to overcharging.
Over-Current Protection (OCP): Shuts down if the battery attempts to draw excessive current.
Short-Circuit Protection (SCP): Immediate shutdown upon detecting a short in the charging circuit.
Reverse Polarity Protection: A feature to prevent catastrophic damage if the user incorrectly connects the charging leads.
