Description
If you’ve upgraded to a lithium-ion battery system, your OEM regulator/rectifier is actively working against your investment. Stock voltage regulators are calibrated for lead-acid chemistry and will overcharge lithium cells, drastically reducing battery life and creating safety risks. Rick’s Motorsport Electric 14-503 is purpose-built with the correct 14V +/- .2 set point to protect and optimize lithium-ion performance, ensuring reliable charging cycles and maximum battery longevity.
This is a direct bolt-on replacement that requires no modifications to your existing wiring harness, making it an ideal upgrade for any Yamaha owner transitioning to lithium power.
