48V 15Ah 18650 lithium-ion battery pack for electric bikes and e-scooters
A 48V 15Ah pack built from 18650 cells, for electric bikes, e-scooters and similar light electric vehicles. Its parameter table is transcribed below from its own listing.

About this model
This pack's listing describes the cell's economy first: the battery cell can provide more than 500 charge and discharge cycles, which the listing says makes it extremely economical and provides an expected life similar to that of the device in which it is used. Its discharge characteristics are low internal resistance and high flat voltage characteristics during strong current discharge, ensuring a wider application field, and its cycle life is long storage life with few limiting conditions, offering problem-free charging after long storage and permitting use in a wide range of applications. The listing adds that premium Li-ion batteries of this kind offer high energy density, long cycle life and safe, reliable performance, with custom packs and bulk orders at competitive wholesale prices.
The 48V nominal voltage at 15Ah stores about 720 watt-hours, and the 30A maximum continuous discharge current covers about 1440W at 48V — a sensible envelope for an e-bike or e-scooter motor with peak demands, provided the motor's peak draw stays within the 30A figure. A buyer should check the vehicle's controller and motor ratings against that figure, because a vehicle whose peak exceeds 30A will trip the pack's protection or sag under load, whatever the capacity. The 5A charging current, the 54.6V maximum charge voltage and the 35.75V discharge cut-off together define the charger and controller window: the charger must be a 48V Li-ion charger at the right voltage, and the controller must respect the cut-off.
The pack's weight, 4.6 kg, and customised dimensions and encapsulation mean the pack is built around the vehicle's battery bay rather than supplied as a fixed block. A buyer ordering this pack should send the vehicle's battery bay dimensions, the motor and controller ratings, and the connector type with the inquiry, and should confirm the certificate set — CE, RoHS, MSDS and UN38.3 as listed — and the one-year warranty in writing for the exact listing. The applications listed for this pack are broad — energy storage, robots, electric scooters, solar systems and general energy storage — but the model description names e-bikes and e-scooters, and a buyer should treat the pack as a light-vehicle pack first and test any other application against its voltage, current and dimensions.

How to read this table
Read the table as a specification for this listing alone. The rated capacity and nominal voltage describe the pack's energy class; the maximum charge voltage and discharge cut-off voltage describe the charger's and the device's voltage limits; the charging current and maximum continuous discharge current describe how fast the pack fills and how hard it can work; the cycle life describes the listing's stated durability; and the dimensions and weight describe the physical pack. No row in this table describes any other model, even one with a similar voltage or capacity.
Two rows deserve a direct question before ordering. The certificate row states what this listing claims, and the certificate set for the exact model should be confirmed in documents, since certificates are available upon request. The delivery and warranty rows state this listing's terms, and they should be confirmed for the exact order quantity, because terms stated for one listing do not transfer to another. A buyer who confirms those two rows in writing has removed the two most common sources of dispute in battery orders.
Confirm before you order
Send the device facts with your inquiry: device type, space, voltage, capacity, peak current, and this model description. Ask for the certificate set for this exact model, confirm the minimum order, price basis and lead time for this listing, and confirm payment and warranty terms before you pay. If the device's space, voltage or peak current differs from this listing, say so in the first line — the custom route, not a forced fit, is the honest next step.

How to place an inquiry, step by step
- Send the device facts. Tell us the device type, the available space (length, width and maximum thickness), the nominal voltage you need, the capacity or runtime you target, and the peak current if your device has motors, radios or heaters.
- Name the model or the chemistry. If a page on this site matches, quote its model description and listing details. If nothing matches, say so and describe the chemistry and voltage you need, so the conversation starts on the custom route.
- Confirm documents and terms in writing. Ask for the certificate set for that exact model, confirm the minimum order, the price basis and the lead time for that listing, and confirm payment and warranty terms before you pay. Terms stated for one model listing do not transfer to another model.
- Agree the sample step. Confirm whether the next step is a listed sample, an engineering sample for a custom design, or a small trial order, and what test you will run on arrival — fit in the enclosure, runtime, or peak-current behaviour.
Send all of this in one message through the contact page: device type, space, voltage, capacity, peak current, model description if you have one, and the documents you need. That is the whole inquiry — no separate form, no account, no extra step.
What to send us now
Send one message with your device type, the space the pack must fit, the voltage and capacity you need, the peak current if it matters, and the model description if a page on this site already matches. Add the documents you need — certificates are available upon request — and whether you need a listed model or a custom design. Use the contact page or write to [email protected], or call +86-755-25629920. A specific message like that is what turns a range of hundreds of models into a short, answerable question.
