Victron BatteryProtect BP-100 - 100AMP - 6-35 VDC

The Victron BatteryProtect BP-100 is a critical power management device designed for serious vehicle builders, off-road enthusiasts, and mobile workshop operators who demand precision battery protection. This 100-amp battery isolator prevents parasitic drain and protects auxiliary systems from catastrophic battery discharge—a concern every mechanic faces when running dual-battery setups, winches, auxiliary lighting, or inverter systems. Whether you're building a dedicated service vehicle, an overland expedition rig, or managing complex electrical architectures in modern trucks and vans, the Victron BatteryProtect BP-100 operates as an intelligent disconnect that safeguards both your primary and secondary power sources.

This device features voltage-sensitive relay technology that automatically disconnects load circuits when battery voltage drops below a preset threshold, protecting lithium and lead-acid chemistries from deep discharge damage. Rated for 6–35 VDC systems, the Victron BatteryProtect BP-100 accommodates 12V, 24V, and 36V configurations, making it versatile across diesel trucks, RVs, marine-based vehicles, and specialized equipment platforms. The compact 3×3×8-inch form factor (1.1 lbs) allows installation in tight engine bays or battery boxes, while the 100-amp capacity handles genuine auxiliary loads—not just trickle circuits. Its sealed, automotive-grade construction resists moisture and vibration, critical for vehicles that see genuine off-road use or high-temperature engine compartments.

Installers benefit from simple two-wire connectivity to auxiliary batteries and loads, eliminating complex relay logic or manual isolation switches. The Victron BatteryProtect BP-100 is ideal for dual-battery systems paired with lithium auxiliary batteries, compressor-driven air suspension, auxiliary winch circuits, or high-draw inverter installations. Technicians upgrading fleet vehicles, expedition builds, or service trucks will appreciate the intelligent protection—no more drained starter batteries after a night of running power tools or auxiliary heating systems. This device integrates seamlessly into Victron Energy systems but operates independently, making it a universal choice for any vehicle requiring voltage-sensitive load isolation.
