BatteryProtect 12/24V 100A protection – is an intelligent electronic switch that disconnects the battery from consumers when the voltage drops below the permissible level. This protects both AGM / GEL and LiFePO₄ batteries from deep discharge, which can seriously reduce the service life or completely destroy the battery.
Thanks to MOSFET technology, the device is silent, does not spark, and also has low internal energy consumption. Automatically recognizes a 12V or 24V system and allows you to set different shutdown/on thresholds via a convenient LED display.
Battery protection against deep discharge is an indispensable component in motorhomes and all their varieties, special streetcars, as well as in sea and river boats, boats and yachts, where batteries are constantly discharged by DC loads.
Key advantages of the BatteryProtec electronic switch
- Automatic detection of a 12/24V system
- Battery protection against deep discharge
- Support for working with lithium batteries (LiFePO₄) – via VE.Bus BMS
- Low current consumption:only 1.5 mA in active mode
- MOSFET switch – no relay, no sparks, silent operation
- Integration with alarm – output for connecting relay, buzzer or LED
- Overvoltage protection – shutdown at >16 V (12V system), >32 V (24V)
- Programmable shutdown/on thresholds via 7-segment LED display
- Load disconnection delay function – 90 s, with warning
- Charging switch mode – for LiFePO₄ via VE.Bus BMS
