1. The Charging Algorithm Revolution

1.1 Lithium Chemistry Dynamics

• Partial charging (20-80%) extends cycle life by 400% vs full cycles
• Voltage sweet spots:
  • 3.92V/cell (optimal storage)
  • 4.10V/cell (daily use max)

2. Thermal Management Science

2.1 Temperature Impact Data

• Capacity loss per 10°C above 25°C (77°F):
  • 1 month exposure: 3.2% irreversible
  • 12 months: 35% capacity degradation

2.2 Seasonal Protection

• Winter protocol:
  • Pre-heat to 15°C before charging
  • Insulated battery blankets
• Summer solutions:
  • Ceramic-coated battery cases
  • Nighttime charging only

3. Connection Maintenance

3.1 Terminal Care

• Quarterly maintenance:
  1. Deoxit D5 spray application
  2. Brass brush cleaning
  3. No-Ox-ID grease application

3.2 Wiring Inspection

• Critical checkpoints:
  • 14AWG minimum for 20A systems
  • Voltage drop <0.3V under load
  • Corrosion indicators:
    • White powder (lead sulfate)
    • Blue-green (copper oxide)

4. Usage Optimization

4.1 Terrain Intelligence

• Grade resistance calculations:

  InclineEnergy Multiplier5°1.8×10°3.2×15°5.7x

4.2 Regenerative Braking

• Proper technique recovers 12-15% energy
• Optimal descent speed: 0.75 x max speed

5. Advanced Diagnostics

5.1 Quarterly Checkups

• Essential metrics:
  • Cell balance variance (<50mV)
  • Internal resistance delta (<15%)
  • Capacity fade rate (%/month)

5.2 Replacement Triggers

• 70% original capacity = end of service life
• Swelling >3mm = immediate replacement

Emergency Protocols

1. Water Exposure:
   • Disconnect within 30 seconds
   • Dry for 72 hours at 35% RH
2. Thermal Runaway:
   • Class D fire extinguisher required
   • 48-hour quarantine after incident
