We design and manufacture smart DC charge control systems for the marine, RV and commercial transportation industries. Our WS500 Advanced Alternator Regulator is the first of its kind to determine battery charge state by factoring battery voltage, amps-in and amps-out, and alternator and battery temperature – and it's the first regulator on the market to communicate with engine and battery BMS systems via CAN communication.

Wakespeed is pleased to announce the availability of user-installable configuration files on the Technical Page of the website. Instructions for the use of these configuration files, and the accompanying installer utility, can be found in the Configuration Utility User Guide.

Firmware V2.2.2 Release


Version 2.2.2 firmware improves coordination between multiple WS500 regulators in twin installs while communicating via CANbus. In addition, Version 2.2.2 firmware offers support for LUX-branded BMS and the ability to invert the meaning of FEATURE-IN port when used with CPE #8 (ref: $SCO command).

The ability to redefine the battery temperature sensor for use with a second alternator is also included in this version. (This can be used in applications where battery temperature is available via CAN, and where dual alternators are being driven by a single WS500 on a single engine. (ref: $SCA command) This new firmware is packaged in a ZIP file, and is available for download on the Technical Page on this website.

REC-BMS Integration


Wakespeed has completed live testing of its integration with the REC Active BMS. The cooperative effort between Wakespeed and Slovenian BMS manufacturer REC enables Wakespeed's WS500 alternator to share connectivity with the REC BMS via a CANbus interface. Through this CANbus connection, the BMS can actively control alternator-based charging to ensure safe and optimal charging of LiFeP04 battery banks.

This marks the third case of successful integration between the Wakespeed WS500 and factory BMS systems — the other proofed integrations are with Lithionics Batteries' Never-Die BMS and MG Energy's MG Master BMS.

Wakespeed Offshore regulators deliver unsurpassed quality and performance for a wide range of applications — our simple WS100 multi-stage voltage regulator offers excellent support for most lead acid battery types in 12-volt systems. The advanced WS500 alternator regulator, with its unique ability to regulate based on voltage, current, and alternator temperature, is by far the most capable charging source for both traditional lead acid and new generation LiFePo4 lithium ion batteries.

All Wakespeed regulators are made in the USA.
