🔋 Introduction
There are three common battery types in energy storage:
- Lithium (LiFePO4)
- AGM
- Gel
Which one is best?
📊 Full Comparison Table
| Feature | LiFePO4 | AGM | Gel |
|---|---|---|---|
| Cycle Life | 4000–6000 | 300–500 | 500–800 |
| DOD | 80–100% | 50% | 50% |
| Efficiency | High | Medium | Medium |
| Lifespan | 10–15 years | 2–4 years | 3–5 years |
🔍 Key Differences
1️⃣ Lifespan
👉 Lithium lasts much longer
2️⃣ Usable Capacity
👉 Lithium provides more usable energy
3️⃣ Maintenance
- Lithium → maintenance-free
- AGM/Gel → periodic care required
4️⃣ Cost Efficiency
👉 Lithium = lowest long-term cost
⚖️ When to Choose Each
LiFePO4
- Best for long-term systems
AGM
- Lower upfront cost
Gel
- Better in deep-cycle than AGM
💡 Final Recommendation
👉 For most modern energy storage:
LiFePO4 is the optimal choice
