Xiaomi Pro 2 / 1S Replacement Battery: Which Fits Your Model?
Xiaomi's electric scooters look almost identical from the outside, which is exactly why so many people order the wrong replacement battery. The truth is that models like the 1S and the Pro 2 use different batteries — and fitting the wrong one means it either won't secure in place or won't deliver the range you expect.
This guide makes it simple. We'll show you the two Xiaomi battery "families", which one fits your exact model, and how to choose the right replacement first time.
Xiaomi Scooters Use Two Battery Families
Almost every popular Xiaomi scooter runs on a 36V battery and charges with the same 42V charger. The difference is the capacity and physical size of the pack, which splits the range into two groups:
- Standard family — around 7.8Ah / 280Wh. Fits the M365, 1S, Essential and Mi 3.
- Pro (long-range) family — around 12.4Ah / 474Wh. A larger pack that fits the M365 Pro and Pro 2.
Key point: The Pro-family battery is physically bigger. It won't sit securely in a standard M365/1S, and a standard battery won't fill the Pro's larger battery bay. Always match to your exact model.
Quick compatibility guide
| Your scooter | Battery family | Typical spec |
|---|---|---|
| M365 / 1S / Essential / Mi 3 | Standard | 36V, ~7.8Ah (280Wh) |
| M365 Pro / Pro 2 | Pro / long-range | 36V, ~12.4Ah (474Wh) |
Specs can vary slightly by version, so always confirm against the label on your existing battery.
Which Battery Fits the Xiaomi 1S?
The Xiaomi 1S uses a standard-family 36V battery (around 7.8Ah / 280Wh). The same pack is shared with the M365, Essential and Mi 3, so a battery listed for any of those will fit your 1S.
Good news: you can also choose a higher-capacity standard-family battery (for example a 9.6Ah or 10.5Ah pack) to get noticeably more range, while keeping the same 36V voltage and connector. That means it's still plug-and-play with your original charger — no modifications needed.
Which battery fits the Xiaomi Pro 2?
The Xiaomi Pro 2 uses the larger Pro-family 36V battery (around 12.4Ah / 474Wh). This is the same pack used by the M365 Pro, so a battery listed for the Pro/Pro 2 is what you need.
Because the Pro 2's battery bay is bigger, do not fit a standard M365/1S battery — it won't secure correctly. Stick to a Pro-family replacement designed for your model.

Can I upgrade my range?
Yes — the easiest, safest upgrade is to fit a higher-capacity battery in the same 36V voltage and the same family as your scooter. This boosts range with no firmware changes and works with your standard charger.
You may see 48V "upgrade" batteries advertised. These can increase top speed but require a different controller and custom firmware, and they need a different charger — so for most riders, staying with a higher-capacity 36V pack is the simpler, hassle-free choice.
What about the charger?
All of these Xiaomi models charge with the standard 42V output charger (for the 36V battery), using the same barrel connector. So if you keep the same voltage, your existing charger will still work. If you've lost or damaged yours, you can pick up a compatible one from our chargers collection.
How to order the right one (checklist)
- Confirm your model — 1S, M365, Essential, Mi 3 (standard) or M365 Pro / Pro 2 (Pro family).
- Match the family — standard (~280Wh) or Pro (~474Wh).
- Check the label — voltage (36V) and capacity (Ah/Wh).
- Decide on range — same capacity, or a higher-Ah pack in the same family for more miles.

Frequently asked questions
Is the Xiaomi 1S battery the same as the M365?
Yes. The 1S, M365, Essential and Mi 3 all use the same standard-family 36V battery, so they're interchangeable.
Can I put a Pro 2 battery in a 1S (or vice versa)?
No. The Pro-family battery is physically larger and won't secure in a standard scooter, and a standard battery won't fit the Pro's larger bay. Match the correct family.
Will a higher-capacity battery work with my original charger?
Yes, as long as you stay at 36V and the same family. A higher-Ah 36V battery gives more range and still uses your standard 42V charger.
How do I know my exact model?
Check the model name printed on the stem or deck, or the label on your existing battery. If in doubt, send us a photo and we'll identify it.
