5. Setup and Installation
5.1 Unpacking and Initial Inspection
Carefully remove the battery from its packaging. Inspect the battery for any visible damage. If damage is found, contact customer support immediately and do not attempt to use the battery.
5.2 Connection
The Oasesenergy 24V 200Ah LiFePO4 battery uses M8 terminals. Ensure all connections are secure and properly tightened to prevent arcing and ensure efficient power transfer.
- Single Battery Connection: Connect the positive (+) terminal of the battery to the positive input of your load/charger and the negative (-) terminal to the negative input.
- Parallel Connection (for increased capacity): Connect positive terminals together and negative terminals together. Ensure all batteries are at a similar state of charge before connecting in parallel.
- Series Connection (for increased voltage): Connect the positive terminal of one battery to the negative terminal of the next. For a 48V system, connect two 24V batteries in series. Ensure all batteries are of the same model and capacity.
When connecting batteries in series and parallel, it is crucial to follow the manufacturer's guidelines for maximum configurations (e.g., 4P2S for 48V 820Ah). Incorrect wiring can lead to severe damage or safety hazards.
5.3 Mounting
Mount the battery in a stable, dry, and well-ventilated area. Ensure it is secured to prevent movement or vibration, especially in mobile applications like RVs or boats. Avoid mounting in direct sunlight or areas prone to extreme temperatures.
6. Operating Instructions
6.1 Charging
Use a LiFePO4 compatible charger with appropriate voltage and current settings. The recommended charging temperature range is 32°F (0°C) to 113°F (45°C). The integrated BMS will protect the battery from charging outside this range.
6.2 Discharging
The battery can be discharged within the temperature range of -4°F (-20°C) to 140°F (60°C). The 200A BMS provides protection against over-discharge, overcurrent, and short circuits.
