When LiFePO4 emerged as new alternatives materials for Lithium ion batteries in 2001, China national research institute began to take researches on those materials for lithium ion battery improvement. After a period of time, Chinese government began to offer support to new energy industry, research institutes also make joint researches with battery enterprises like BYD, BAK etc. The predecessor of Bestgo Battery is a core technical team from China national research institute, which have over 16 years' experience on li-ion batteries, 12 years joint research experience on LiFePO4 batteries (data checked in 2020). After years of independent researches on battery materials, the break though technologies have been developed then Bestgo Battery have been founded, company resisted in Hongkong and run factory in Changzhou city, southeast of China, total covers 20,000 square meters and about 200 workers. Bestgo batteries are featured as high power density and ultra-safe performance, due to the updated materials, manufacturing method and safety design.
Not like traditional organic solvents manufacturing method, Bestgo have cells been made under the nano-level pure water dissolving manufacturing way, which makes benefits for a higher level of quality control, processing optimization and labor saving. This manufacturing method requires much more capital invests in production lines for the fully automatic machines and high precision control equipments. They are acting much better for the key manufacturing steps with full zone monitoring and realtime feedback. Bestgo have cells been made in those manufacturing process, which can greatly enhance the consistency of cell performance, quality reliability for the longterm use, obtain a quite good production yield ratio and reach environmental friendly, to produce the most advanced vehicle level lithium ion batteries.
LiFePO4 battery is the safest battery available for lithium ion batteries. However, to enhance this safety, Bestgo makes many efforts in this area. We adopted the ceramic separators among anode and cathode in cells, used premium electrolyte for a better performance and safety level, used silicon-carbon mixed anode for a better charging capability for some power type cells. We designed the patent modules and softlink busbars to resist high vibration conditions, applied the thermal conductive designs in package structure, use totally sealed metal case for priority, which makes our batteries have high safety reliability when meet very hard conditions.
With years of experiences in design and manufacturing of li-ion batteries for different applications, we have built many different projects for customers.
We deliver advanced Li-ion battery packs with well designed module structure and reliable BMS, customer can also equip their preferred BMS in local market so can have fast response services. Our battery packs are widely used in low speed electric vehicles, light traction vehicles, if customer have good advanced BMS, we can offer high quality battery modules to support build in series up to 750V battery system running in high speed vehicles. Our engineers have rich experience in design of battery systems for vehicle application, our unique technology can make sure cells have high level standards in battery packs, for example we can make sure cell voltage in the same battery packs have cell voltage difference no more than 20mv at 50%SOC.
The Li-NCM 37Ah cells and 48Ah cells we make are manufactured based on vehicle standards. in the year of 2019 here are over than 2,000 vehicles running on road which equipped 355V185Ah battery packs made by 37Ah cells. In the early years here are over than 10,000 vehicles running on road which equipped the battery packs made by 32Ah cells (In the late of 2018 we updated 32Ah cell type to 37Ah cell type).
The LiFePO4 30Ah cell has very high energy density (163Wh/kg), long cycle life, and LiFePO4 chemistry has the best safety among li-ion cells. They are very popular in applications which needs high safety assurance and longer cycle life. Those 30Ah cells share the exactly same module structure to Li-NCM 37Ah cells, so they can be made to standard aluminum case battery modules, those modules have well designed thermal management, shock-absorbing and weight-reduction. They can be managed by advanced BMS (Battery Management System) for the monitoring and controlling, to make the reliable battery systems.
We have ultra light weight battery modules with low profile shape, that can be used to build battery packs as "skate shape" in chassis of electric vehicles. This type of module has height of 102mm, width of 370mm and length extensible, which has cassette sheet structure module and use ultra light weight 48Ah pouch cells.

Bestgo Battery is dedicated to providing advanced lithium ion batteries which feature both high power and energy densities with a long lifespans and ultra-safe performance. The cells are made using some unique manufacturing technologies developed over the years. These completely automated unique battery construction processes allow Bestgo to build the high reliable quality lithium batteries with nice cost achieved in mass production.
To ensure our battery quality, we start by purchasing high quality raw materials and then assemble these materials on the production lines using automated equipments, along with the latest in manufacturing processes and a high degree of precision quality control. For instance, the LiFePO4 materials for battery are supplied by quality suppliers which have authorization of Phostech in Canada, Other materials like separators are imported from qualified suppliers in Japan and famous companies of China. We then use laser equipments to detect the thickness in the coating process. These laser equipments communicate with the coating machines in a feedback system to maintain tight tolerances and make sure that no cells are produced outside preset limits. We deployed the PDMS (Product Data Management System) for quality control, every step in the manufacturing process is checked, logged and judged, so that if a problem occurs it will be discovered early and any faulty product would be discarded. This automated attention to every step of the manufacturing process results in higher yields and ultimately lower production costs.
Every cell produced at Bestgo's factory is individually electrically tested on automated testing equipment and the test results logged into Data Management System. The results are that we can then offer well matched cells for battery packs. When we need to choose the best candidate cells for battery packs, we use this Data Management System to calculate the cell's electric properties for the best selection. The testing parameters include the internal resistance, capacity, self-discharge rate, voltage and charge / discharge curves etc. These are the reasons why our battery packs have a superior quality over other competitors.
We offer battery packs with Battery Management System (BMS) integrated if customers order these packs with protective regulated circuitry. The active balancing function of BMS will transfer energy from the higher cells to lower cells in the pack when the battery pack is being charged or discharged. This balancing and control function assures the user that all cells will have almost the same voltage, capacity and have less chance of being damaged due to overcharging or over discharging.
