Victron Energy Battery monitor BatteryProtect

The BatteryProtect disconnects the battery from less important consumers before it is fully discharged (which would cause damage) or before it no longer has enough energy to start the engine. It features automatic detection of the voltage range for 12/24 V systems. The BatteryProtect automatically recognizes the system voltage. Easy programming allows the BatteryProtect to be set to turn on or off at various voltages. The seven-segment display indicates which setting has been selected. There is a special setting for lithium-ion batteries. In this mode, the BatteryProtect can be controlled by the VE.Bus BMS. Note: The BatteryProtect can also be used as a charge breaker between a battery charger and a lithium-ion battery. It has an extremely low power consumption, which is important for lithium-ion batteries, especially after being turned off due to a low voltage level. Please also refer to our data sheet on lithium-ion batteries and the VE.Bus BMS manual for more information. Overvoltage protection ensures that sensitive consumers are not damaged by overvoltage, as the load is always disconnected when the DC voltage exceeds 16 V or 32 V. Explosion protection is provided by using MOSFET switches instead of relays, eliminating the risk of sparking. There is an output for a delayed alarm. The alarm output is activated when the battery voltage falls below the preset cutoff value for more than 12 seconds. Therefore, starting the engine does not activate the alarm. The alarm output is a short-circuit protected open collector output connected to the negative (minus) rail, with a maximum current of 50 mA. The alarm output is typically used to activate an acoustic signal, an LED, or a relay. There is also a load disconnection and reconnection delay feature.
