Wakespeed WS500

WS500 charge regulator

The WS500 is the only alternator regulator available that can utilize current, voltage and temperature to deliver the most precise and effective charging possible for 12V, 24V and 48V battery systems – with configurability for voltages in between – making it the perfect solution for charging lead acid based, or new generation LiFePO4 lithium-ion battery banks.

• Wide ranging support for both traditional lead acid and new lithium battery technologies
• Advanced, multi-PID engine control provides the most accurate charging available
• Easy to install, configure and operate
• Best charge control for lithium battery chemistries
• Superior protection for your investment

Wakespeed WS500: The Benchmark Advanced Marine Alternator Regulator

The Wakespeed WS500 is one of the most advanced and intelligent external alternator regulators available for the marine market. Engineered to maximize onboard charging performance, it stands out for its exceptional capability to manage complex electrical systems and next-generation battery banks with extreme precision.

• Multi-Parameter Control (Voltage, Current, and Temperature): Unlike traditional regulators that rely solely on voltage, the WS500 simultaneously monitors voltage, current (via a shunt), and temperatures (both alternator and battery bank) to optimize charging in real-time and prevent overheating.
• Full Compatibility with Lithium (LiFePO4) and Traditional Batteries: It natively supports AGM, Gel, Flooded, and advanced lithium systems, applying tailored and protective charge profiles (including specialized profiles for safeguarding lithium cells).
• Voltage Versatility: Automatically recognizes 12V, 24V, and 48V systems, making it highly adaptable for custom high-output and off-grid setups.
• CAN Bus and BMS Integration: Featuring CAN connectivity (J1939 protocol / compatible with systems like Victron Cerbo GX), it can interface directly with Battery Management Systems (BMS) for a fully closed-loop, safe charging process.
• Smart Built-In Technologies:
  • Adaptive Idle Technology: Dynamically reduces the alternator load at low RPMs (idle) to prevent engine strain or stalling.
  • Thermal Management: Actively throttles output based on alternator temperature to protect against thermal stress and damage.
