Do Not Order by Model Name Alone

Use the H9 model name only as a starting point. Confirm the physical battery system against your original bike before ordering. A matching 48V / 15Ah label is not enough by itself—the housing, rail, connector and polarity must also match.

01

Confirm the Bike Version

Check model generation, production year or version information where available.

02

Compare the Housing

Compare case shape and approximate dimensions with your original battery.

03

Check the Mounting Rail

The slide rail and locking points must align with your existing bike mount.

04

Verify Connector & Polarity

Connector shape and positive/negative polarity must match before installation.

Battery Check

Match the Physical Details

Look at the battery top, charge indicator, key position, charging port and case profile. Small hardware differences can matter even when voltage and capacity are the same.

Lock & Rail

Compare the Locking Side Before Purchase

Compare the lock position, side profile and lower mounting interface with your original battery. If the rail or latch differs, the battery may not seat correctly.

FAQ

Replacement Battery Questions

Is this battery guaranteed to fit every OUXI H9?

No. Model generations and component revisions can differ. Compare the original battery and mounting system before ordering.

Can I judge compatibility only by 48V 15Ah?

No. Voltage and capacity are only part of the check. Housing, rail, connector and polarity also matter.

Which charger voltage is used?

A 48V lithium-ion battery normally uses a 54.6V charger. Confirm the charging plug before use.

What if my battery case looks different?

Do not force installation. A different case or rail may indicate a different battery revision.
