Reliable voltage regulation for modern and classic motorcycles - now suitable for lithium-ion batteries

• Plug & Play replacement for SH632-12, SH633-12, SH638-12, SH639-12, SH609-12, SH701-12, SH691-12, among others
• MOSFET technology: more stable, cooler, and suitable for lithium-ion batteries
• Built-in temperature protection prevents overloading
• Perfect protection for your battery, alternator, and onboard electronics
• Ideal to combine with the Shido LTX9 HP Lithium-Ion battery

Are you looking for a regulator / rectifier for your Honda that is not only reliable but also ready for the future? The Carmo CARR581 is a direct, plug-and-play replacement for the SH632-12, SH633-12, SH638-12, SH639-12, SH609-12, SH701-12 and SH691-12 regulator / rectifiers, among others. But with modern MOSFET technology and compatibility with lithium-ion batteries.

This MOSFET regulator / rectifier is designed with reliability, heat management, and electrical stability in mind. While conventional regulator / rectifiers often become hot and allow voltage to pass through when faulty, the CARR581 continues to operate safely and coolly thanks to built-in temperature protection. If the regulator / rectifier does become too hot, it temporarily switches itself off to prevent damage to your battery or electronics. Once the temperature drops, it automatically resumes the charging process - without any intervention from the rider. Safety and convenience in one!

Why MOSFET? Traditional regulator / rectifiers use thyristor technology, which works but is inefficient. A MOSFET regulator / rectifier such as the CARR581 switches much more precisely and produces less heat. The result: less energy loss, more stable charging voltage, and less battery wear. This also makes the regulator / rectifier particularly suitable for use with modern lithium-ion batteries, which are sensitive to voltage spikes and overcharging.

Protect your motorcycle and electronics

A faulty or overloaded regulator / rectifier can cause serious damage. Excessive charging voltage can permanently damage electronic components, ECUs, or even batteries. The Carmo CARR581 provides active protection against this. The temperature-sensitive cutoff acts as a last line of defense against overloading and is an essential safety mechanism missing from many standard regulator / rectifiers.

Easy installation and guaranteed fit

The CARR581 is fully Plug & Play: no modifications are required, and the connectors fit directly. For optimal operation, preferably mount the regulator / rectifier on a well-cooled surface, such as the original mounting point. If the regulator / rectifier still becomes too hot during normal use, this is often a sign of a problem elsewhere - such as a faulty battery, alternator, or poor ground connection.

Which models is it suitable for?

This regulator / rectifier is suitable for a wide range of Honda motorcycles, including models that are fitted with an SH632-12, SH638-12, or SH701-12 as standard. Always consult the original specifications or contact us to confirm compatibility.

You receive a standard 3-year warranty on this quality product from Carmo Electronics - Dutch craftsmanship with a worldwide reputation.
