+86 13502886530A1: Yes, our factory is in Shenzhen, china. Specializing in rechargeable batteries. Lithium ion batteries, lithium batteries and power batteries and chargers for more than 10 years.
A2: All of our e-bike batteries come with charger.We have normal charger and fast charger.If you need fast charger please contactwith us
A3: Yes, Our batteries all with SEIKO IC BMS, with stable performance.Which can protect the battery avoid short circuit,Overcharged,Overdischarge and Overcurrent.
A4: Electric Bike Battery will be sent out within 5 days after confirmed order,shipping will cost 3-15days,it depend on quantity and which battery you need.
The battery should have around 800-1200 recharge cycles, about 2-3 years.Its capacity diminishes over time, when it goes down to 75%,you should replace it.The more you use the bike, the better the battery retains its capacity, since it keeps the Lithium moving.
The battery should be stored in clean, dry, ventilated, dark environment when not using.Keep it after full charge,recharge it every 3 months or 6 months.
Yes, We are a professional Electric Bike Battery manufacture with factory, which produce all kind of high quality Ebike lithium batteries as customers' requirements and designs, welcome to place OEM and ODM orders and visit our factory.
Ebike Li-ion battery have longer cycle life,normal cyclelife is 6000-8000times, and also with light weight, small size, No-memory effect, Nontoxic, environmental.
The price come with Bus bars and Bolts，One Battery will come with one set bus bar and bolt（e.g.,If buy 4pcs battery,we will send 4pcs cells with 4pcs busbars and 8pcs bolts）If need more please contact us online.
Pack with strong package, each cell into thickness PE foam or bag, then into 5 layers strong carton.

Customerized 48V LiFePO4 battery pack
To create a customized 48V LiFePO4 battery pack, several factors need to be considered, including the desired capacity, configuration, dimensions, and intended application. Here's a general process for us to make such a battery pack:
Determine Requirements: Understand the specific requirements for the battery pack. This includes voltage (48V), capacity (measured in ampere-hours, Ah), discharge rate, size constraints, weight limitations, and any other relevant factors.
Select Cells: Choose the appropriate LiFePO4 cells for the battery pack. We choose the grade A and original branded new LiFePO4 battery, 16 pieces 3.2V 100ah, 200ah,300ah, Ensure they meet the required specifications and quality standards. Consider factors such as energy density, cycle life, safety features, and availability.
Calculate Configuration: Determine the configuration of the battery pack, including the number of cells and their arrangement (series and parallel connections). This calculation will depend on the desired voltage (48V) and capacity requirements.
Design Enclosure: Design or select an enclosure for the battery pack that meets safety, durability, and size requirements. Consider factors such as heat dissipation, protection against physical damage, and ease of installation.
BMS Selection: Choose a Battery Management System (BMS) suitable for LiFePO4 chemistry and compatible with the desired voltage and capacity of the battery pack. The BMS is essential for monitoring cell voltages, balancing cells, and providing overcharge/discharge protection.
Assembly: Assemble the battery pack according to the planned configuration and design. This typically involves spot welding or soldering cells together, connecting them in the desired series/parallel configuration, and integrating the BMS.
Testing: Perform comprehensive testing on the battery pack to ensure it meets performance and safety standards. This includes capacity testing, voltage measurements, temperature monitoring, and verifying proper BMS functionality.
Integration: Integrate the battery pack into the target application, whether it's an electric vehicle, renewable energy system, or another device. Ensure proper connections, cooling (if required), and safety precautions are implemented.
Quality Assurance: Conduct ongoing monitoring and quality assurance to ensure the long-term reliability and performance of the battery pack. This may include regular maintenance, monitoring cell balance, and replacing components as needed.
Regulatory Compliance: Ensure compliance with relevant regulations and standards for battery packs, such as UN38.3 for transportation and safety standards like UL or IEC.
Throughout this process, it's essential to prioritize safety and quality to prevent issues such as thermal runaway, overcharging, or short circuits, which can lead to safety hazards or premature failure of the battery pack. If you're not experienced in designing or assembling battery packs, it's advisable to seek assistance from professionals or companies specializing in battery technology.
