Grepow Inc. Is a US-based company dedicated in providing the best battery products, services, and solutions to customers in all industries. With many years of experience in the industry, Grepow has successfully developed special-shaped Li-Po batteries. These batteries are not confined to the traditional square shape, so every shape is possible, such as triangle, round, and curved shapes. The special shape of the battery can thus fill in the usually empty space in a product, which ultimately increases the battery capacity, as well as the run time.
