Li-ion / LiFePO4 Pouch Cell List
LiFePO4 3.2V 10Ah pouch cells
Bestgo Power offers high quality Li-ion polymer cells for the assembly of battery packs. The pouch cells build very thin shape for heat passing and internal resistance reduction. Single cells can be made in big capacity so that the assembly of whole pack became easy as numbers of cells reduced quite a lot.
The package foil of cells is a type of aluminum and elastic fibers mixed materials which come from Japan based company (Showa). The aluminum improved the heat passing efficiency, the strong elastic fibers help foil has strong strength and good extension. If batteries meet severe damage, it may generates a lot of heat and some gas, the package foil can be blown up like a balloon but still hold them, not allow any leakage of gas or liquid, that is very nice safety design.
To enhance the high temperature reliability, we applied a unique step to send all unfinished cells into 75 degree Celsius oven for 2 hours, to force gas out and also be treat as a test for high temperature resistance. Our battery materials are nice so that they can withstand this high temperature, then we promise pouch cell made by us is no problem in high temperature condition as we specified. The electrolyte of our pouch cell is semi-solid state among plates, better than liquid type which may have leak out of cell.
While all manufacturing processes are exactly supervised by the advanced PDMS (Product Data Monitoring System), for every step in manufacturing, parameters of cells would be automatically logged and judged, if any fault cells would be mark and pick out. This system also logged the electrical properties of every cell in quality testing procedures. For battery package step, system would calculate those parameters and offer the best candidates cells for pack assembly, by this way our battery packs got a superior consistency than other competitors.
Some of those cells reached 4000+ cycles in our lab test, as 1C charge / discharge cycles in room temperature for about 2 years..

Bestgo Power offers excellent energy storage solutions based on our advanced lithium ion batteries.
For cell level, we develop and manufacture advanced Lithium Iron Phosphate (LiFePO4) and Li-NCM batteries, which has high power and energy densities along with long lifespan and ultra-safe performance. For module level, we have frame structure modules and cassette structure modules which can be configured in a convenient way, modules are designed to enhance the structure reliability and simplify the installation for energy storage system. For battery pack level, we use PDMS system to select cells which has closest consistency. Cells will be assembled to battery pack with BMS built in and metal or plastic case protected. Customer could specify the detail requirements regarding cell type, dimensions, weight, voltage, capacity, constant and peak power etc. We accept customize order as an OEM service.
Bestgo Power makes high quality lithium ion batteries. We deployed fully-automatic manufacturing lines controlled by all time all steps auto feedback monitoring & adjusting system. We take high quality battery materials, eco-friendly manufacturing way, fully automated equipments and abundant safety design to ensure the reliability of cell performance. For instance the LiFePO4 materials for pouch cells come from quality suppliers which have authorization of Phostech in Canada, battery separators for high power cells come from USA and cell foils come from Japan.
Bestgo LiFePO4 cells made in 2011 have cycled 4000+ times in lab as 100%DOD test with 1C charge and discharge. The latest EV level pouch cells proven by vehicle standard in China and cells are built for battery packs which now equipped on hundreds of electric vehicles running every day.
Bestgo Power developed several kinds of module structures which have reliable inside structure and standard outside connections. They can be easily configured in parallel and series to reach specified voltage and capacity. The entire system will be very flexible in adjusting overall dimension, voltage and capacity. Since modules are independent components from BMS, the project can choose BMS freely as application required. Those features could save a lot of labor works in structure design and help people to focus on build entire system as they wanted.
Bestgo Power offer OEM service to make quantity volume battery packs according to customer requirements. For the reliable performance, we use single cells which are manufactured by the latest manufacturing way under the automatic monitoring-feedback system. All materials for cells are sourced from famous companies in Japan, Taiwan and China. With professional matching system, we can choose the best identical cells for cell pack, this make sure the superior consistency and high reliable in steady performance. For the package stage, we have patented structure methods like block type structures, cassette sheets structures and so on to build cell pack, we will design suitable battery case for cell pack with BMS built in and necessary components. The whole pack will be delivered as “ready-to-use” products with a high reliable quality.
