The listing advertises direct factory delivery in 7 to 10 working days and a direct supplier warranty. These conditions come from the source; confirm current timing and terms with the shop before ordering.
The supplier table also covers 36V/48V, several wheel sizes and different configurations. Check the ordered variant: front, rear cassette and threaded-freewheel figures refer to distinct configurations.
Advertised battery: 48V 15Ah, dimensions 365 × 90 × 110 mm. The overview describes a black hard-plastic shell, a lightweight battery that is easy to fit and remove, an LED charge indicator, a USB port for devices and a mounting base with key-operated lock.
The source advertises overvoltage protection and a sealed casing for difficult conditions, plus a BMS against overcharging, overdischarging, excessive current and short circuits. It describes stable input/output and capacity for extended use. These statements are not a certification verified here.
The mounting base is described as fitting most bottle-cage mounting holes. The battery is offered for 48V electric bikes, converted conventional bicycles and mountain bikes; check space, fixings and electrical compatibility.
Advertised battery package: 1 battery, 1 base plate, 1 charger, 1 EU mains cable, 1 instruction manual, 2 base-plate fixing screws and 2 keys.
Source precautions: avoid water; keep cool and dry when unused; avoid excessive heat and fire; use only the supplied charger; observe polarity; do not connect the battery directly to a mains socket; do not put it in a fire or on a radiator.
Do not short-circuit with metal objects or store alongside them; do not solder or puncture; keep away from high temperatures and areas with static electricity. If leaking material contacts the eyes, rinse with water and seek medical help. Stop use immediately if the battery shows abnormal signs.
Clean dirty terminals; insulate terminals for disposal. The source states to recharge after depletion and every three months during long storage; follow charger and manufacturer instructions for charging level and storage.
