The BatteryProtect Smart BP-220A disconnects non-essential loads from the battery before it is completely discharged. 

BatteryProtect Smart BP-220A

The BatteryProtect Smart BP-220A is an advanced device designed to protect batteries by disconnecting non-essential loads before the battery becomes completely discharged. This prevents battery damage and ensures sufficient energy is available for critical functions, such as starting the engine. It is ideal for 12/24V systems and compatible with LiFePO4 lithium batteries, thanks to its auto-regulated design and advanced features.

Applications of the BatteryProtect Smart BP-220A

1. Battery protection: Prevents deep discharges that can damage lead-acid or lithium (LiFePO4) batteries.
2. Solar and wind systems: Perfect for safeguarding batteries in off-grid solar installations.
3. Vehicles and boats: Ensures batteries retain enough power to start engines.
4. Backup power systems: Automatically disconnects non-essential loads during prolonged power outages.
5. Lithium battery systems: Compatible with Battery Management Systems (BMS) for efficient lithium battery management.

Advantages and benefits of the BatteryProtect Smart BP-220A

1. Automatic and programmable disconnection:

   • Protects the battery by disconnecting non-critical loads when a low voltage threshold is reached.
   • Automatically reconnects when the voltage rises above the pre-set level.

2. LiFePO4 lithium battery compatibility:

   • Features a special mode for lithium batteries controlled by a BMS.
   • Supports direct control through the VE.Bus BMS system.

3. 12/24V auto-regulation:

   • Automatically detects system voltage, eliminating the need for manual setup.

4. Ultra-low power consumption:

   • Ideal for lithium systems, minimizing power draw after a low-voltage disconnection.

5. Overvoltage protection:

   • Disconnects loads if the voltage exceeds 16V (12V systems) or 32V (24V systems) to protect sensitive devices.

6. Fireproof design:

   • Utilizes MOSFET switches instead of mechanical relays, eliminating sparks and enhancing safety.

7. Delayed alarm output:

   • Activates an alarm only if low voltage persists for over 12 seconds, preventing false alarms when starting an engine.

8. Delayed load disconnection and reconnection:

   • Disconnects the load 90 seconds after the alarm is activated. If voltage recovers during this time (e.g., after starting the engine), the load will not be disconnected.
   • Reconnects 30 seconds after the voltage exceeds the reconnection threshold.
