Victron Energy Battery undervoltage protection BP-65i 12/24V 65A Bluetooth

Battery undervoltage protection BP-65i 12/24V 65A Bluetooth

The undervoltage protection disconnects the load from the batteries before the battery is completely discharged, which could quickly destroy the battery. Or it disconnects the battery before it has enough power to start the engine.

12/24V automatic setting.
BatteryProtect automatically detects the system voltage and adjusts to it.

Bluetooth technology: easily programmable
When using Bluetooth technology to program Smart BatteryProtect, arbitrary levels of connection / disconnection of the load from the battery can be set.
Alternatively, you can set one of the nine pre-set connection / disconnection levels (see manual). Bluetooth can be turned off if necessary.

Special settings for Li-Ion batteries
In this mode, BatteryProtect can be controlled via the VE.Bus BMS.
Note: BatteryProtect can also be used as a charge interrupter between the battery charger and the lithium ion battery.

Very low energy consumption
Low consumption is very important for Li-ion batteries, especially after switching off at low voltage.

Overvoltage protection.
BatteryProtect has a built-in overvoltage protection function, it disconnects the load at a voltage of 16.3V or 32.6V. This will protect sensitive devices.

No sparks.
The design of the undervoltage protection is an encapsulated MOSFET, so there is no sparking on the switching elements.

Output for alarm with delay.
This output can be used to power the alarm if the voltage drops below the set limit for a period longer than 12s. Therefore, starting the engine does not activate the alarm. It is typically used to turn on an alarm or light, but it can also be used to turn on a charger or generator. Relay output is max 500mA.

Disconnection of the load with a delay - after 90 seconds from the alarm, the load will be disconnected, if during this time there is an increase in voltage (start of the alternator, charger, etc.), the disconnection will not be activated.
