To ensure battery quality, 70% of our battery packs are manufactured by Panasonic, LG, Sanyo and Samsung. The remaining 30% is composed of high-performance, high-discharge rate and low-resistance Chinese Class A batteries. These batteries are usually used in new energy electric vehicles, but we use these batteries in your products, and these Chinese-made Class A batteries are more affordable than other imported batteries. Not because of their poor quality. China is paying more and more attention to environmental protection, we are very clear that new energy vehicles are the future direction of automobile development. Therefore, our country strongly supports and subsidizes the new energy vehicle industry, so that such economical and high-quality products are available. In addition, we have 26650 32650 lithium iron phosphate batteries(LiFePO4),used in industry to replace lead-acid batteries. Of course, what kind of battery cells to use depends on you, we will choose the right cells according to your needs.
