Safely Charge Lithium From Your Alternator
The RCB+ Charge Relay is designed to share the charging power of an alternator between a starting battery and a service battery, in both 12VDC and 24VDC systems. You can use the RCB+ to regulate the current being delivered to your service battery using the rotary wheel, setting it between 50 and 120A (adjustable model).
The RCB+ is also compatible with lithium batteries, allowing you to safely use your alternator to charge lithium batteries without risking damage to your alternator.
Prevents Alternator Overload: Built-in low-frequency switching mode stabilizes output current and prevents reverse voltage damage.
Fully Adjustable (30A - 120A): Manually set the maximum charge limit to perfectly match your specific alternator size.
12V & 24V Auto-Detect: Compatible out of the box with both 12VDC and 24VDC marine electrical systems.
Heavy Duty Capability: Can be safely used with high-output marine alternators up to 200A.
Marine-Grade Build: Compact, lightweight, and ruggedly designed for the harsh marine engine room environment.
