The BatteryProtect BP-100 automatically disconnects non-essential loads to prevent battery damage or preserve power for engine cranking. Designed as a uni-directional device, it handles current flow in only one direction—either from battery to load or from charger to battery. Current flows exclusively from the Battery terminal to the Load terminal, ensuring safe and reliable operation whether protecting loads or managing charging systems.
Product Features:
- 12/24V Auto Ranging: Automatically detects system voltage for hassle-free installation.
- Easy Programming: Allows selection of various engage/disengage voltages, displayed via a built-in seven-segment indicator.
- Li-ion Battery Compatibility: Includes a special setting for use with VE.Bus BMS; can also act as a charge interrupter between a charger and a Li-ion battery.
- Ultra Low Current Consumption: Minimizes power draw—especially important for Li-ion batteries after low voltage shutdown.
- Over Voltage Protection: Automatically disconnects the load if voltage exceeds 16V (12V systems) or 32V (24V systems) to protect sensitive electronics.
- Ignition Proof: Uses MOSFET switches instead of relays—eliminating sparks for safer operation.
-
Delayed Alarm Output: Triggers after 12 seconds of low voltage to avoid false alarms; ideal for use with buzzers, LEDs, or relays (max 50 mA).
