Introduction
Incorrect battery connections can cause imbalance, overheating, and premature battery failure. Proper series and parallel configuration is essential.
1. Series Connection Rules
Used to increase system voltage:
- Batteries must be identical (brand, capacity, age)
- Uneven batteries cause voltage imbalance
2. Parallel Connection Rules
Used to increase capacity:
- Cable lengths must be equal
- Use busbars for large battery banks
3. Avoid Mixed Configurations
Never mix old and new batteries or different battery models in the same system.
4. Balancing and Monitoring
Battery monitoring systems help detect voltage deviation early and prevent irreversible damage.
Conclusion
Proper wiring design maximizes energy efficiency and prevents costly system failures.
