100A Voltage Sensitive Relay - 24V Split Charge, Campervan & Commercial

100A Voltage Sensitive Relay (VSR) — a high quality 24V voltage sensitive relay designed to safely manage split charging between a primary (starter) battery and a secondary battery bank, without the risk of draining your main battery.

By monitoring system voltage, the relay automatically connects the secondary battery only when sufficient charging voltage is present. When voltage drops, it disconnects, ensuring the starter battery remains protected at all times.

Ideal for 24V campervans, commercial vehicles, trucks, and specialist conversions, this relay offers reliable, automatic operation with no manual switching required. A built-in red LED indicator provides clear visual confirmation of relay status.
