Red Machined Lithium-Ion Battery Compatible Regulator for Honda Kawasaki Polaris Suzuki Triumph Yamaha 1993-2025
Red Machined Lithium-Ion Battery Compatible Regulator for Honda Kawasaki Polaris Suzuki Triumph Yamaha 1993-2025
PLEASE NOTE : This voltage regulator is ONLY for lithium batteries THIS IS NOT FOR LEAD ACID BATTERIES. Output Voltage is the key factor in a voltage regulator designed specifically for Lithium batteries. The ideal charging voltage for Lithium batteries is 13.9-14.2VDC. The RMSTATOR regulator has a carefully set output voltage of 14.1VDC (+/- 0.1VDC). This stable and ideal output voltage carefully keeps a lithium battery in it’s ideal charging range.
Please contact the manufacturer of your Lithium Ion Battery to ensure our product has the correct set point for their product
Protect your investment in an expensive lithium battery with our lithium battery voltage regulator!
Battery condition is extremely important. No stator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.

Brand new Lithium-Ion Batteries Compatible MOSFET Voltage Regulator (CNC)
WORKS WITH LITHIUM BATTERIES ONLY
Our new red machined aluminum MOSFET voltage regulator is a great upgrade for heat dissipation in any powersports charging system. After 10 minutes of use, our billet aluminum heatsink runs cooler by 33% than standard cast regulator housings. Our new red regulator, equipped with the renowned Mosfet regulation technology, is an added value to any three-phase permanent magnet charging system.
STOP BURNING YOUR REGULATOR RECTIFIER !
It is time to update or replace your voltage regulator with the advanced MOSFET type.
It runs cooler than all OEM diode style regulators. In addition, this rectifier has overheat protection, rather than burn up, it will simply turn off for a while and cool off.
- Direct replacement to your original unit
- Plug-and-play, direct fit, easy installation
- The quality exceeds the OEM equipment
- Improved heat sink and charging capabilities
- Higher grade of electric components
- All shipped products are tested
We have even included the opposite connector (main harness side) as we know these are often melted / corroded / defective and a major cause of repetitive electrical issues.
*All item pictures are accurate, if in doubt, do not hesitate and compare our item to your original part.
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 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.
Why use Mosfet Enhanced technology?


Runs cooler
Runs much cooler than the traditional Shunt voltage regulator rectifier.

Saves gas
Less load on the stator, less work, less fuel is used and you save.

Regulated energy
The power charging your battery is steadier and smooth.

Extended battery life
Extends the battery’s life and cold cranking capacity.

More engine power
Removes stator load resulting in more engine power.

Optimized power
Optimize power delivery by switching the stator coils on or off.
How does a Mosfet regulator rectifier work?
With design
This product is an advanced design that lowers operating temperatures for extended longevity and better performance than the OEM part.
