Description
If you’ve upgraded to a lithium-ion battery system, your stock regulator/rectifier is working against you—it’s calibrated for lead-acid chemistry and will either undercharge or overcharge your lithium cells, drastically shortening battery life and risking electrical system damage. Rick’s Motorsport Electric Regulator/Rectifier is engineered specifically for lithium-ion applications, delivering precise voltage regulation that maximizes battery performance and longevity. This is a direct bolt-on replacement that requires zero fabrication, making it the essential component for any serious lithium upgrade.
