BatteryProtect 220A

The BatteryProtect 220A is designed to disconnect non-essential loads from the battery before it is fully discharged. This protects the battery from potential damage and ensures there is enough power left to start the engine.

The BatteryProtect 220A can handle a continuous maximum charge current of 220 amperes. It is also capable of supporting a peak current of 600 amperes for a duration of 30 seconds.

Yes, the BatteryProtect 220A features automatic voltage detection, making it compatible with both 12V and 24V systems. Its operating voltage range is 6 to 35V.

The current draw of the BatteryProtect 220A is very low:

1.5 mA in normal operation0.6 mA in stop mode or after a low-voltage cutoffThis low consumption is particularly important for Li-ion batteries, especially after a shutdown due to low voltage.

Yes, the BatteryProtect 220A includes overvoltage protection. It automatically disconnects the load if the DC voltage exceeds:

16V for a 12V system32V for a 24V systemThis feature is essential to prevent damage to sensitive loads.

The BatteryProtect 220A features a timed alarm output. This alarm activates if the battery voltage drops below the predefined disconnect level for more than 12 seconds. The delay prevents false alarms, for example during engine start-up.

The default thresholds for the BatteryProtect 220A are as follows:

Disconnect threshold: 10.5V or 21VDisconnect threshold: 12V or 24VThese thresholds are automatically adjusted based on the detected system voltage (12V or 24V).

The BatteryProtect 220A can operate at full load within a temperature range from -40°C to +40°C. It can support up to 60% of its nominal load at 50°C.

Yes, the BatteryProtect 220A is flame-resistant. It uses MOSFET switches instead of mechanical relays, eliminating spark generation and improving installation safety.

Yes, the BatteryProtect 220A comes with a pre-assembled DC ground cable and connector, simplifying installation.

Yes, the BatteryProtect 220A has a dedicated setting for Li-ion batteries. In this mode, it can be controlled by an external battery management system (BMS) such as the VE.Bus BMS or the Lynx Smart BMS. If the BMS signal becomes floating, the load disconnection is immediate and without delay.

The BatteryProtect 220A is not designed to be directly connected to the DC inputs of inverters or chargers due to the risk of reverse currents that could damage it. To control these devices, it is imperative to use the BatteryProtect to command their remote control port.

No, the BatteryProtect is a unidirectional device. It is designed to allow current to flow only from the IN terminal to the OUT terminal. It can handle current to a load or from a charger (if oriented correctly), but not both simultaneously. It is not designed for reverse currents from charging sources.

The BatteryProtect 220A must be installed in a well-ventilated area, preferably within 50 cm of the battery. However, do not install it directly above the battery due to potential corrosive gases.

During wiring, it is crucial to:

Choose the correct cable size and length to match the load to avoid voltage drops. Insert a properly rated fuse between the battery and the BatteryProtect, in compliance with local regulations. Respect the correct current flow direction (IN to OUT). Use the supplied 1.5mm² wire for the GND connection, which must be directly connected to the battery’s negative terminal.

The BatteryProtect 220A automatically detects system voltage (12V or 24V) only once during the initial power-up. The selected voltage is then stored, and further automatic detection is disabled.

To reset the voltage detection and allow the BatteryProtect to detect the system voltage again, you must follow the specific programming procedure outlined in the manual, using parameter "d" from the programming table.

The BatteryProtect 220A uses M8 terminals for power connections. The recommended torque for these terminals is 9 Nm.

The BatteryProtect 220A has two IP classifications:

IP67 for the electronics: This means the internal electronics are fully protected against dust and can withstand temporary immersion in water. IP00 for the connections: This indicates the connection terminals are not protected against contact with fingers or solid objects and require adequate protection during installation.

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 driven high (connected to the battery positive) to activate the BatteryProtect.
