Meta Description: Discover whether connecting two 36V lithium batteries in series is safe and efficient. Learn technical requirements, applications, and best practices for industrial and renewable energy systems.
Understanding Series Connections for 36V Lithium Batteries
Connecting two 36V energy storage lithium batteries in series is a common question among engineers and renewable energy enthusiasts. While series connections can boost voltage, they require careful planning to avoid safety risks like overheating or battery degradation.
💡 Pro Tip: Always check your battery manufacturer's specifications before attempting series connections. Not all lithium batteries support this configuration.
Key Considerations for Safe Series Connections
- Voltage Doubling: Two 36V batteries in series create 72V – ideal for high-power industrial equipment.
- Capacity Consistency: Both batteries should have identical Ah ratings (e.g., two 100Ah units).
- BMS Compatibility: Battery Management Systems must communicate effectively in series setups.
Industry Applications & Market Demand
Series-connected 36V lithium battery systems are transforming multiple sectors:
| Industry | Application | Market Growth (2023-2030) |
|---|---|---|
| Solar Energy Storage | Residential power walls | 18.3% CAGR* |
| Telecom Infrastructure | Backup power systems | 9.7% CAGR |

Real-World Case: Solar Farm Optimization
A recent project using EK SOLAR's 36V lithium batteries achieved 22% efficiency improvement through series-connected storage. The system now powers 50kW irrigation pumps during peak demand hours.
⚠️ Critical Safety Note: Never mix batteries from different manufacturers in series configurations. Internal resistance mismatches can cause catastrophic failures.
Implementation Best Practices
- Use matched battery pairs from the same production batch
- Install voltage balancing circuits
- Monitor temperature differentials (keep below 5°C variation)

FAQ: Series Connection Essentials
Can I connect different capacity batteries in series?
No – capacity mismatches cause accelerated degradation. Always use identical Ah-rated units.
What happens if one battery fails in series?
The entire circuit fails. Implement redundant monitoring systems to prevent cascade failures.
