A1: 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.

Performance characteristics
High safety: equipped with one-way safety valve, when the internal pressure of the battery is too large, the safety valve will release gas and heat, prevent the battery from burning and explosion, even in the case of internal and external damage, high temperature, short circuit, etc., it can effectively ensure safety.
Long cycle life: in the case of 80% deep discharge (DOD), a single battery after 3000 cycles, the discharge capacity can still be maintained at more than 80%, some products can even reach more than 6000 cycles, long service life.
Strong temperature adaptability: can work in the temperature range of -20 ℃ to 65℃, good performance in high temperature environment, can work normally at 65℃; In low temperature environment, the discharge capacity decreases by not more than 22% at 0℃ and not more than 30% at -20℃.
High charge and discharge efficiency: Support fast charging, can be charged to 80% in 20 minutes, full charge takes 2-3 hours. The standard discharge current is 0.3C-0.8C, and the instantaneous pulse discharge current can reach 10C for 10 seconds, which can meet the high power requirements of a variety of equipment.
Stable output: The discharge platform is stable and can provide stable voltage output during the whole discharge process to ensure the stable operation of electrical equipment.
Green environmental protection: no pollution in the production and use process, in line with environmental protection requirements, friendly to the environment.
Application field
Energy storage system: such as household, commercial and grid energy storage, can store solar energy, wind energy and other renewable energy generation electricity, when needed to release, play a peak to fill the valley, stable power supply role.
Electric vehicles and electric vehicles: Power electric cars, electric bicycles, electric motorcycles, golf carts, sightseeing vehicles, etc., to meet their long range and high safety requirements.
Backup power supply: Used for uninterruptible power supply (UPS), emergency lighting and other fields, to provide temporary power support when the power grid outage, to ensure the normal operation of important equipment.
Marine and aviation fields: can be applied to the power system of ships, small aircraft, drones, etc., to provide reliable power and electric protection.
Other fields: It can also be used in power tools, portable electronic equipment, medical equipment, military equipment and other fields to meet the power needs of different equipment.
