- Use appropriate gauge cables for parallel connections to handle increased current.
4.4 Initial Charging
It is recommended to fully charge the battery before its first use.
- Connect the charger to the battery's charging port.
- Plug the charger into a standard AC power outlet.
- The charger will indicate charging status (refer to charger's specific indicators).

5. Operation
5.1 Powering On/Off
Once installed and connected, the battery is ready for use. The BMS automatically manages power delivery and protection. There is no manual power button on the battery itself; it activates upon connection to a load.
5.2 Monitoring Battery Status
You can monitor the battery's status through two methods:
- Integrated Touch Monitor: The battery features a built-in touch screen display that shows real-time information such as State of Charge (SOC), voltage, current, temperature, and individual cell voltages.
- Bluetooth App: Use the LOSSIGY smartphone app to remotely view detailed battery parameters and historical data.
5.3 Usage Guidelines
- The battery is designed for deep cycle applications, offering 100% Depth of Discharge (DOD).
- The 200A BMS provides a peak current of 1000A (for 3-5 seconds), suitable for demanding applications like golf cart acceleration or trolling motor bursts.
- Ensure the continuous load does not exceed the maximum continuous current of 150A (5760W).
- For optimal lifespan, avoid consistently discharging the battery to its absolute minimum.
