48V 15Ah Replacement Battery for OUXI H9
Replacement lithium battery for compatible OUXI H9 fatbikes. Confirm the original battery system before ordering.
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.
Confirm the Bike Version
Check model generation, production year or version information where available.
Compare the Housing
Compare case shape and approximate dimensions with your original battery.
Check the Mounting Rail
The slide rail and locking points must align with your existing bike mount.
Verify Connector & Polarity
Connector shape and positive/negative polarity must match before installation.
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.
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.
Confirm Your Bike Before Ordering
Use your bike and original battery together as the reference. Do not rely only on the H9 logo or model name.
