2. Safety Information
Your DC HOUSE lithium battery is engineered with multiple safety features to ensure reliable and secure operation. Please read and understand all safety instructions before installation and use.
2.1 Metal Case & Dual Safety Design
The battery features a durable metal case, which provides superior protection compared to traditional ABS cases. In the event of thermal runaway, the metal case effectively contains flames and high-temperature molten materials, preventing fire spread. It is also equipped with a pressure relief valve and a power safety switch for increased battery safety and reduced energy consumption.
- Pressure Relief Valve: Automatically opens in extreme conditions (e.g., thermal runaway, short circuit) to prevent hazards.
- Power Safety Switch:
- Turns off output when unused for extended periods, preventing over-discharge and extending battery life.
- Allows for safer installation and maintenance by cutting off voltage.

5. Operating Instructions
5.1 Powering On/Off
To power on the battery, ensure the safety switch is in the "ON" position. To power off, switch it to "OFF". It is recommended to turn off the battery when not in use for extended periods to conserve energy and prolong battery life.
5.2 Monitoring Battery Status
The DC HOUSE battery offers two methods for real-time monitoring of its status:
- Bluetooth APP: Download the dedicated DC HOUSE app to your mobile phone. Connect to the battery via Bluetooth to view data such as State of Charge (SOC), voltage, current, and temperature. The app allows monitoring within a 15-meter range.
- LCD Monitor: The included LCD monitor (dimensions: 2.76*0.98*1.77 inches) can be connected to the battery to display key information.
Note: The mobile APP and LCD display are both connected via Bluetooth and cannot be used simultaneously. Choose one method for monitoring at a time.
