3.2 Mounting Location
Choose a dry, cool, and well-ventilated location for mounting the battery. Ensure the location is free from direct sunlight, heat sources, and moisture. The battery is IP65 rated for dust and water resistance, but prolonged exposure to harsh conditions should be avoided.
3.3 Wiring Connections
- Ensure all power sources are disconnected before making any connections.
- Use appropriate gauge cables for your application to handle the expected current.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your load/charger.
- Connect the negative (-) terminal of the battery to the negative (-) terminal of your load/charger.
- Ensure all connections are tight and secure to prevent loose connections and potential arcing.
- If connecting multiple batteries in series or parallel, refer to the "Advanced Configurations" section.

3.4 Advanced Configurations (Series/Parallel)
The HumsiENK 12V 320Ah battery supports configurations up to 4S4P (4 series, 4 parallel) for increased voltage and capacity. This allows for a maximum system of 51.2V 1280Ah (65.5 kWh).
- Parallel Connection: Connect positive to positive and negative to negative terminals to increase capacity while maintaining the same voltage. Ensure all batteries are at a similar state of charge before connecting in parallel.
- Series Connection: Connect the positive terminal of one battery to the negative terminal of the next battery to increase voltage. Ensure all batteries have the same capacity and are fully charged before connecting in series.
- Always use a qualified electrician for complex wiring configurations.

4. Operating Instructions
This section details the general operation of your HumsiENK LiFePO4 battery, including charging, discharging, and using the Bluetooth monitoring feature.
4.1 Initial Charge
It is recommended to fully charge the battery before its first use. Use a LiFePO4 compatible charger with appropriate voltage and current settings.
4.2 Charging and Discharging
- Charging Voltage: Typically 14.2V - 14.6V for a 12V system. Consult your charger's manual for optimal settings.
- Charging Current: The maximum continuous charging current is 250A. Avoid exceeding this limit.
- Discharging Current: The maximum continuous discharging current is 250A. Peak discharge current is 300A for 10 seconds, or 600A for 1 second.
- Operating Temperature:
- Charge: 0°C to 45°C (32°F to 113°F)
- Discharge: -20°C to 65°C (-4°F to 149°F)
- Storage: 0°C to 60°C (32°F to 140°F)
- The BMS will automatically cut off charging if the temperature drops below 0°C (32°F) to protect the battery.
