📌 Original 53.6V vs. 54.6V: Why it Changes Everything

On the Xiaomi Scooter 4 Pro Plus electric scooter , the charger supplied by the manufacturer is often set to ≈ 53.6V instead of 54.6V. The idea is to prevent a battery stored just after charging from remaining at 100% for too long. In reality:

• Charging to 100% for immediate driving is no problem; it is prolonged storage at 100% that accelerates aging.
• At 53.6V , you never start with 100% usable capacity : part of the full tank is missing.
• Most BMS only balance the cells near the maximum voltage . If 54.6V is never reached, the balancing remains incomplete, which causes imbalances and cuts in the long term.

A 54.6V charger therefore allows 100% capacity to be recovered , the pack to be correctly rebalanced and the battery life to be extended .

Tip: Fully charge to 54.6V before riding . For extended storage, keep the battery between 30% and 60% .

❓ FAQ – Xiaomi Scooter 4 Pro Plus (48V – 54.6V 2A)

➡️ 53.6V vs 54.6V: what's the difference and why is it important?

53.6V (original charger) keeps the battery just under full charge to limit wear in storage, but reduces the usable capacity and prevents complete balancing of the BMS . Conversely, 54.6V (maximum voltage of a 13S pack) ensures a complete charge and perfect balancing , essential to preserve performance and avoid premature shutdowns.

➡️ Can I use both chargers?

Yes, occasionally. To maintain good balance:

• Perform a full charge to 54.6V every 2–3 weeks .
• After the green light turns green, leave the charger connected for 30–60 min for the BMS maintenance phase.

➡️ Is 2A suitable?

Yes. 2A is the standard current for the Xiaomi 4 Pro Plus's 48V/13S batteries: safe charging, controlled heating, and optimal longevity.

➡️ Best practices?

Recharge before every ride. For extended breaks, keep the battery between 40% and 60% and periodically charge to 54.6V to rebalance.

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

Not necessarily. The red → green transition marks the end of the main charge, but the BMS continues to balance. Leave the charger for an additional 30–60 minutes from time to time.

➡️ Typical charging time?

At 2A , count approximately capacity (Ah) ÷ 2 hours (e.g.: 12 Ah ≈ 6 h). The final balancing phase may extend the duration slightly.

➡️ Compatibility:

This model is for the Xiaomi Scooter 4 Pro Plus . It is compatible with: Xiaomi MI4 Pro Plus , Xiaomi 4 Pro Max , Xiaomi 5 MAX and Segway ZT3 Pro .
