Victron BatteryProtect 12/24V-100A

12/24V Auto-Ranging

• Automatically detects whether the system is 12V or 24V.

Easy Programming

• Set custom engage/disengage voltage levels.
• A clear seven-segment display shows which setting is selected.

Optimised for Li-ion Batteries

• Includes a special mode for Li-ion systems, allowing control via the VE.Bus BMS.
• Can also function as a charge interrupter between a charger and a Li-ion battery (see manual for wiring diagram).

Ultra-Low Current Consumption

• Particularly important for Li-ion batteries after a low-voltage shutdown. See the Li-ion battery datasheet and VE.Bus BMS manual for details.

Over-Voltage Protection

• Automatically disconnects loads if DC voltage rises above 16V (12V systems) or 32V (24V systems), preventing damage to sensitive equipment.

Ignition Proof

• Uses MOSFET switching instead of relays—no sparks.

Delayed Alarm Output

• Alarm triggers only if voltage remains below the disconnect threshold for more than 12 seconds, preventing false alarms during engine cranking.
• Short-circuit proof open collector output (max. 50 mA) for driving a relay, LED, or buzzer.

Delayed Disconnect & Reconnect

• Loads disconnect 90 seconds after the alarm activates, unless voltage recovers within that time.
• Loads automatically reconnect 30 seconds after voltage rises above the preset reconnect level.
