72V e-scooter batteries require an 84V charger. Here's the complete guide.
Why 84V?
72V Li-ion battery = 20S pack. Full charge = 20 x 4.2V = 84V.
Current Selection
- 84V 2A: Standard charging for 20Ah battery (10+ hours)
- 84V 5A: Fast charging for 20Ah battery (4-5 hours)
- 84V 10A: Ultra-fast for 40Ah+ batteries
Connector Types
- XT60: High-current standard for e-scooters
- Aviation plug: Industrial-grade secure connection
- 3-pin XLR: Some scooter models
Safety Considerations
- 84V is high voltage - ensure proper insulation
- BMS must support the charging current
- Use thick enough cables (min 14AWG for 5A+)
- Always include over-voltage and over-temperature protection
