Stop burning your voltage regulator rectifier! It is time to update or replace your voltage regulator with the advanced MOSFET type.

It runs cooler than all SCR diode-style OEM regulators. In addition this rectifier has overheat protection rather than burn up it will simply turn off for a while and cool off.

Top Features:

• Direct replacement to your original unit
• Plug-and-play direct fit easy installation
• The quality exceeds the OEM part
• Higher grade of electric components

Opposite connector (main harness side) included as we know these are often melted/corroded/defective and a major cause for repetitive electrical issues.

Why do you need a different voltage regulator for lithium batteries?

Lithium batteries have different charging requirements than Lead Acid or AGM batteries that can severely affect their lifespan and performance. The key factors in safe and reliable lithium battery charging are the output DC voltage ripple and average output voltage. The RMSTATOR regulator is designed around the optimal parameters for these factors.

The ripple effect is all that matters

Charging voltage ripple in a Powersports application is the difference between the highest and lowest voltages from the voltage regulator output. By nature a common shunt style voltage regulator will have a fairly high voltage ripple due to the regulation shunt switches opening and closing frequently. Each on/off transition will cause some variation in the output voltage this is unavoidable. Keeping this to a minimum is critical for Lithium batteries and the RMSTATOR Lithium regulator is designed around this feature.

In a perfect world a ripple of less than 10% of the output voltage (~1.5V for a typical regulator) would be ideal however is not practical for this type of regulator. The RMSTATOR Lithium regulator is able to maintain a less than 4 Volts output ripple compared to verified test results of our competitors 8 volts. Keep in mind this ripple voltage is only seen via an Oscilloscope sampling the voltage 1000’s of times a second and is not the same as your average charging voltage as measured by a multimeter.
