Upgrade your marine charging system with the Balmar Regulator Kit for Valeo Alternators (MC-618-VL-01), engineered to deliver precise, multi-stage voltage regulation for improved battery performance and longer battery life. This complete kit pairs Balmar’s advanced MC-618 external voltage regulator with the correct wiring harness and mounting hardware for seamless integration with Valeo alternators.
Designed for marine and RV electrical systems, the MC-618 regulator provides smart charging profiles, temperature compensation, and customizable programming to safely charge AGM, gel, and flooded lead-acid batteries. By optimizing alternator output, this regulator kit helps prevent overcharging, reduces heat stress on your alternator, and ensures faster, more efficient battery replenishment—ideal for cruising, liveaboard, and off-grid power setups.
Multi-Stage Charging: Features 8 selectable programs to optimize bulk, absorption, and float stages for various battery chemistries.
Valeo-Specific Integration: Includes the custom VL-01 harness, making it compatible with Valeo 60A, 80A, and 120A alternators.
Lithium Ready: Includes a pre-set Lithium profile to ensure safe and efficient charging of LiFePO4 house banks.
Belt Load Manager: Allows you to reduce the alternator's horsepower draw to protect your engine belts from premature wear or slippage.
Smart Dash Integration: Compatible with the Balmar SG200 Battery Monitor for real-time alternator data on your smartphone or MFD.
