Competitive Advantages:

Company advantages:

1-Good Quality Management:
Our Pack production base for mass order have passed TS16949 Quality System, ISO14001 Environmental System and OHSAS18001 system certifications. And we have passed the test of the National Motor Vehicle Product Quality Supervision and Inspection Center. We always do daily production as per these systems.

2-Advanced hardware and software facilities

We established high-precision three-coordinate measuring machines, projectors, universal material tensile machines, and other measuring instruments to ensure the effective quality data.

3-Technical advantages:

Our technical team are all from China famous electric vehicle manufacturers. They all have more than 10 years' industry experiences. They have excellent R&D abilities. We also have the ability to develop BMS by ourselves.

Product advantages:

Our products are of high quality because

The cells we use are domestic high-quality cellsfrom China big cell manufacturers or imported cells from Sumsang, Panasonic.LG, etc .

BMS are realiable. BMS within 24S, we develop by ourselves. BMS above 24S, we purchase from China top 3 BMS manufacturers.

Advanced battery pack assembly technologies ensures the finished battery packs are of high quality.

YM Power Tech Limited is a professional lithium-ion batteries supplier that offers custom-made services for different specifications of lithium-ion battery packs and system integration. Of course, lithium-ion cells, BMS chargers, etc can be supplied as well.

YM is our brand. YM has two meanings. That is Yoctometer(ym) Tech Powers Yottameter(Ym). Although Yoctometer tech now is hard to achieve (the most advanced level now is Nanotech), powering yottameter is much possible. Our aim is to use the most advanced technology to make the best lithium batteries.

YM's lithium batteries are widely used as power batteries for different kinds of electric vehicles, such as electric scooters, electric cars, electric motorcycles, AGV, golf carts, electric wheelchairs, etc. Besides, YM lithium batteries are also applied as storage batteries, such as for home solar storage systems, backup power supply, UPS, solar street light, RV, etc.

Except for pure lithium batteries, YM also offers solutions to the complete EV powertrain kit and the complete energy storage system, including not only lithium batteries but also motors, motor controllers, charge controllers, inverters, etc. OEM & ODM services are offered.

YM's products have won many national invention patents and some products have passed the CE certificate. At present, YM has cooperated with many low-speed electric vehicle manufacturers in China.

By 2019, YM has built an R&D center, domestic sales office, and production factory. Production factory covers an area of 2000+ square meters with 1 manual production lines and 1 automatic production line. The annual production capacity can reach 1GWh. The factory has got ISO9001 quality management system certified and ISO14001 and OHSAS 18001 certified.

In 2020, YM started to develop overseas business. It is believed that YM will do a good job in the international market!
