Choose Your BMS Version: 30A or 40A Continuous Discharge
Our batteries come with two BMS options. The continuous discharge current determines what motor power your battery can safely support:
🔋 30A BMS Version
Recommended for: 500W - 750W motors
Power Output: 48V × 30A = 1,440W peak power
Ideal For: Standard e-bikes, city commuters, flat terrain riders
Perfect for daily commuting and casual riding where extreme power isn't needed.
⚡ 40A BMS Version
Recommended for: 750W - 1,200W motors
Power Output: 48V × 40A = 1,920W peak power
Ideal For: High-performance e-bikes, cargo bikes, steep hills, off-road riding
Choose this for demanding conditions where extra power and headroom are essential.
📋 How to Choose:
- Check your motor's wattage rating (usually printed on the motor)
- Consider your typical terrain - hills need more power
- Factor in your weight plus any cargo you carry
- When in doubt, choose the 40A version for future-proofing
Note: Both versions include all the smart Bluetooth features above. The only difference is the maximum continuous discharge current.
Professional Cell Mounting System
Our 48V 20Ah battery features a precision-engineered frame that securely holds each Samsung 50G cell in place. This rigid structure provides essential protection against vibration, impacts, and physical stress during rides.
The individual cell compartments maintain proper spacing for optimal heat dissipation and prevent cell-to-cell contact. This design ensures long-term structural integrity and minimizes the risk of damage from expansion or movement.
By using a professional frame instead of simple tape wrapping, we deliver enhanced safety, extended battery lifespan, and consistent performance—key factors that distinguish premium e-bike batteries from basic alternatives.
