Ninebot Segway ZT3 PRO FAST Charger

Ninebot Segway ZT3 PRO Charger – 48V (54.6V) 4A – Fast charging with active ventilation

High-performance 54.6V – 4A charger for Ninebot Segway ZT3 PRO electric scooters equipped with a 48V (13S) lithium-ion battery . This Source'IT fast charger halves the charging time compared to the original standard charger, while maintaining a controlled temperature and perfectly regulated voltage to preserve the battery's lifespan.

🔧 Technical specifications

• Output Voltage: 54.6V DC (full charge of a 13S pack at 4.2V per cell)
• Charging current: 4A (fast version – 4× faster than a standard 1.3A charger)
• Connections: Specific connector for Ninebot Segway ZT3 PRO
• Cooling: active ventilation
• LED indicator: red = charging / green = charging complete
• Built-in protections: overvoltage, overload, overheating, short circuit, reverse polarity
• Compatibility: Ninebot Segway ZT3 PRO (48V – 13S Li-ion)

📌 Original 53.6V vs. 54.6V: Why it matters

The original charger of the Ninebot Segway ZT3 PRO is limited to ≈ 53.6 V to reduce the float voltage during storage. However, this value prevents a full charge of the pack and limits performance:

• At 53.6 V , the battery only reaches 95% of its useful capacity: immediate loss of autonomy.
• The BMS (Battery Management System) only balances the cells near 54.6 V. At 53.6 V, balancing remains incomplete, promoting internal imbalances.
• A full charge to 54.6V is only harmful if the battery is stored for several days in a full state. If you ride immediately afterward, this is the optimal voltage.

The Source'IT 54.6V charger provides full capacity and complete cell balancing , maximizing the runtime and life of your ZT3 PRO battery.

Tip: Fully charge to 54.6V before each use, and for long-term storage, keep the battery between 30% and 60% .

❓ FAQ – Ninebot Segway ZT3 PRO charger (48V – 54.6V 4A)

➡️ Is the 4A charger safe for my battery?

Yes. 48V (13S) lithium batteries can easily handle a 4A charge. The Source'IT charger incorporates intelligent electronic regulation and active cooling to limit overheating.

➡️ What is the difference between 2A and 4A?

2A charges slowly, making it ideal for occasional use. 4A charges about 4 times faster : for example, a 12.5 Ah battery charges in ≈ 3 hours instead of 10 hours.

➡️ Can I replace my 53.6V charger with a 54.6V one?

Yes, without risk. 54.6V corresponds to the full charge voltage intended for 13S lithium batteries. This guarantees perfect balancing of the BMS and maximum autonomy .

➡️ Should I unplug as soon as the LED turns green?

Not necessarily. The green light indicates the end of the main charge, but the BMS continues to balance the cells. Leave the charger connected for an additional 30 to 60 minutes from time to time.

➡️ Temperature and safety

Thanks to its integrated active ventilation , the Source'IT 4A charger maintains a low temperature even at full power, preventing overheating and extending battery life.
