BatteryProtect 12/24V-100A

Victron Energy’s BatteryProtect 12/24V-100A is a protection device designed to automatically disconnect non-essential loads from the battery. This prevents a full discharge that could damage the battery or ensures sufficient power remains to start an engine, for example.

The BatteryProtect 12/24V-100A automatically detects the system voltage (12V or 24V) on first power-up. It is compatible with systems operating at both voltages.

The BatteryProtect 12/24V-100A has an ultra-low current draw. It consumes 1.5 mA when running and only 0.6 mA in standby mode or during a low-voltage cut-off.

Yes, the BatteryProtect includes overvoltage protection. It disconnects the load if the continuous voltage exceeds 16V for a 12V system, or 32V for a 24V system, to protect sensitive equipment.

The BatteryProtect 12/24V-100A can handle a maximum continuous charging current of 100 amperes.

Yes, the BatteryProtect is ignition-proof. It uses MOSFET switches instead of relays, ensuring no sparks during operation.

The low-voltage alarm is triggered if the battery voltage drops below the preset disconnect level for more than 12 seconds. This prevents the engine start from triggering the alarm. The alarm output is an open-collector output protected against short circuits, with a maximum current of 50 mA.

The default thresholds for BatteryProtect are as follows:

Disconnect: 10.5V for a 12V system or 21V for a 24V system. Reconnect: 12V for a 12V system or 24V for a 24V system.

The dimensions of the BatteryProtect 12/24V-100A are 59 x 42 x 115 mm (height x width x depth). Its weight is 0.5 kg.

The BatteryProtect can operate at full load within a temperature range of -40°C to +40°C. It can handle up to 60% of its rated load at 50°C.

The BatteryProtect must be installed in a well-ventilated area, preferably close to the battery, within a maximum distance of 50 cm. It should not be installed directly above the battery due to potential corrosive gases.

Yes, a properly sized fuse must be inserted in the cable between the battery and the BatteryProtect, in accordance with local regulations. Additionally, the ground (GND) cable must be protected by a 300mA fuse.

The BatteryProtect is a unidirectional device. Current must flow only from the "IN" terminal (input, connected to the battery) to the "OUT" terminal (output, connected to the load). Reverse currents from the "OUT" terminal to the "IN" terminal are strictly prohibited and will damage the device.

The 1.5 mm² ground cable provided must be connected directly to the negative terminal of the battery (or to the vehicle chassis). No other equipment must be connected to this wire. This cable must also be protected; a 300 mA fuse is sufficient.

The recommended tightening torque for the connections (M8 terminals) of the BatteryProtect 12/24V-100A is 9 Nm.

Yes, the BatteryProtect 12/24V-100A has a special setting for Li-ion batteries. In this mode, it can be directly controlled by an external BMS such as the VE.Bus BMS or the Lynx Smart BMS for optimized discharge management.

It is strictly forbidden to directly connect inverters or inverter-chargers to the BatteryProtect DC inputs, as backfeed current could damage the device. To control such equipment, you must use the BatteryProtect to manage its remote control port.

Yes, a remote on/off switch can be connected between the two pins of the 2-pin remote terminal. Alternatively, the terminal labeled "REMOTE" can be powered (connected to the battery positive) to activate the BatteryProtect.

Yes, the BatteryProtect can also be used as a charging switch between a battery charger and a Li-ion battery. It is important to refer to the connection diagram in the manual for this configuration.

Yes, the BatteryProtect is compatible with lead-acid batteries (including AGM, Gel, and flooded) in 12V and 24V systems, thanks to its programmable disconnect and reconnect thresholds.
