Setup
Series & Parallel Battery Connection
The CyperOcean 12V 314Ah LiFePO4 battery supports configurations up to 4 Series (Max) and 4 Parallel (Max). This allows for expandable energy storage up to 51.2V 1256Ah, providing a massive 63.48kWh energy system.
Warning:
When connecting batteries in series or parallel, use a multimeter to measure the battery voltage. It must be ensured that the voltages of all batteries are consistent, or the voltage difference is less than 0.2V. Connecting batteries beyond this range is prohibited.
For example, taking a 12.8V 200Ah battery:
- Series: Four 12.8V 200AH batteries in series equal 51.2V 200AH.
- Parallel: Four 12.8V 200AH batteries in Parallel equal 12.8V 800AH.
- Max. Connection in Series & Parallel (4S4P): A 4S4P configuration of 12.8V 200Ah batteries gives 51.2V 800Ah.

Maintenance
Storage Guidelines
- Charge the battery to 50% capacity before storage.
- Disconnect all load connections when storing.
- Store in a dry, well-ventilated area with temperatures between 0°C~60°C (32°F~140°F), avoiding extreme heat or cold.
- Recharge to 50% capacity every 3 months if stored long-term to prevent over-discharge.
Low-Temperature Protection
The integrated BMS automatically cuts off charging in low-temperature conditions (below -4°F / -20°C) to prevent irreversible battery damage and ensure longevity, especially in extreme climates. The maximum discharge temperature is 158°F (70°C).
Multi-layered Protection
The battery is designed with robust protection features:
- IP65 Waterproof: Provides protection against dust and water jets.
- Dust Protection: Prevents ingress of dust particles.
- Low-temp Cut Off Protection: Automatically stops charging in cold conditions.
Troubleshooting
The built-in 200A Battery Management System (BMS) provides all-round protection against common issues. If the battery is not functioning as expected, the BMS may have activated one of its protection mechanisms:
- Over-Voltage Protection: Prevents charging beyond safe voltage levels.
- Over-Current Protection: Shuts down if current draw exceeds safe limits.
- Short-Circuit Protection: Protects against damage from short circuits.
- Over-Charge Protection: Prevents damage from excessive charging.
- Over-Discharge Protection: Prevents the battery from being drained too low, which can cause irreversible damage.
- High/Low-Temperature Protection: Regulates operation within safe temperature ranges, cutting off charging/discharging if temperatures are too extreme.
If a protection is triggered, disconnect the load or charger, allow the battery to return to normal operating conditions (e.g., temperature), and then attempt to restart. If issues persist, consult the full technical manual or contact support.
User Tips
- Users have reported this to be an excellent product, highlighting its reliability and performance.
- Always verify the voltage of individual batteries with a multimeter before connecting them in series or parallel to ensure they are within 0.2V of each other. This prevents damage and ensures balanced operation.
- For optimal battery life, avoid consistently discharging the battery to 0% DOD. While the battery supports nearly 100% DOD, shallower discharges can extend overall cycle life.
- When storing the battery for extended periods, ensure it is charged to approximately 50% capacity and recharged every three months to prevent deep discharge and maintain health.
- Take advantage of the low-temperature cut-off feature. If operating in cold environments, ensure the battery is not charged below -4°F (-20°C) to protect its internal chemistry.
