Best for: Most applications including home storage, EVs, solar systems

LTO (Lithium Titanate)

Available in: Yinlong 12V 30Ah/40Ah packs

Advantages:

• Ultra-long life: 20,000-30,000+ cycles

• Lightning-fast charging: 6-15 minutes full charge

• Extreme temperature operation: -50°C to +60°C

• Superior safety: No thermal runaway risk

• Zero maintenance: Truly fit-and-forget

Trade-offs:

• Higher cost: 3-5x more expensive than LiFePO4

• Lower energy density: 50-80 Wh/kg

• Heavier for same capacity

Best for: Applications where extreme longevity, fast charging, or harsh conditions matter most

Step 3: Key Technical Specifications to Evaluate

1. Capacity Requirements

Calculate your needs:

Daily Energy Need (Wh) = Power Rating (W) × Usage Time (h)

Required Capacity (Ah) = Energy Need (Wh) ÷ System Voltage (V)

Add 20-30% safety margin for depth of discharge

Quick Reference:

• 100-105Ah: 320-336Wh per cell

• 230Ah: 736Wh per cell

• 280Ah: 896Wh per cell

• 314Ah: 1,004Wh per cell

2. Cycle Life Expectations

• Budget applications: 4,000+ cycles (EVE standard models)

• Premium applications: 6,000-7,000+ cycles (CATL, EVE 314Ah)

• Lifetime applications: 20,000+ cycles (Yinlong LTO)

3. Physical Constraints

Consider these dimensions:

• Compact: 130×38×130mm (100Ah/105Ah)

• Standard: 207×174×72mm (230Ah/280Ah/314Ah)

• Complete packs: 12V ready-to-use (Yinlong)

Weight considerations:

• Lightweight: 2.1kg (100Ah/105Ah)

• Moderate: 4.14-5.49kg (230Ah-314Ah)

• Complete systems: 4.2-5.1kg (Yinlong packs)

4. Performance Characteristics

Internal Resistance (Lower = Better):

• Excellent: ≤0.18mΩ (CATL, premium EVE)

• Good: ≤0.25-0.5mΩ (Standard EVE models)

• LTO advantage: Extremely low resistance

Energy Density:

• High: 162-177 Wh/kg (LiFePO4)

• Moderate: 50-80 Wh/kg (LTO)

• Ultra-high: Up to 270 Wh/kg (some Li-ion)

Step 4: Budget Considerations

Cost-Effective Options

For maximum value, choose:

• EVE 230Ah: Best cost per kWh ratio

• EVE 280Ah: Proven reliability at reasonable price

• EVE 100Ah/105Ah: Low entry cost for small projects

Premium Performance

When budget allows, upgrade to:

• CATL 280Ah/314Ah: Industry-leading quality

• EVE 314Ah: Maximum capacity in standard size

• Yinlong LTO: Lifetime investment with 30,000+ cycles

Total Cost of Ownership

Consider over 10 years:

• LiFePO4: Replace 1-2 times, lower upfront cost

• LTO: Buy once, higher initial investment, zero replacements

Step 5: Environmental & Operational Factors

Temperature Requirements

• Standard LiFePO4: -30°C to +60°C operating

• Premium LiFePO4: -40°C to +60°C (CATL)

• LTO extreme: -50°C to +60°C operation

Charging Speed Needs

• Standard charging: 4-6 hours (LiFePO4)

• Fast charging: 2-3 hours (Premium LiFePO4)

• Ultra-fast: 6-15 minutes (LTO)

Safety Priorities

All options offer excellent safety, but:

• LTO: Virtually impossible to cause thermal runaway

• LiFePO4: Extremely stable, non-toxic, safe for indoor use

Final Selection Checklist

Before making your final decision, confirm:

• Energy Requirements: Calculated daily kWh needs

• Physical Space: Available dimensions and weight capacity

• Budget Parameters: Upfront cost vs. total ownership

• Performance Needs: Charging speed, cycle life, temperature

• Future Expansion: Easy scaling possibilities

• Technical Support: Available expertise for installation

Pro Tips for Success

1. Start Small, Scale Up: Begin with fewer cells and expand as needed

2. Mix Capacities Carefully: Stick to same capacity within parallel strings

3. Plan Your Configuration: 16 cells for 48V, 8 cells for 24V, 4 cells for 12V

4. Invest in BMS: Never operate without proper battery management

5. Buy Authentic: Only purchase from authorized distributors
