  • NeoRRow series curved lipo smart ring batteries are specially launched by Grepow to meet the needs of the smart wearable market. The NeoRRow series curved ring batteries are made of the world's leading silicon and carbon anode material, molded in one piece with exquisite craftsmanship, and equipped with bi-directional lugs, which effectively reduces the width of the battery and improves the energy density. Grepow NeoRRow series curved ring batteries are designed to provide the best battery solution for smart ring products. The NeoRRow series curved smart ring batteries are equipped with a boule coating on the pole piece, which realizes the safety isolation of the positive and negative electrodes, and prevents the internal short-circuit effectively. The production process adopts a fully self-designed production line with a stacked-piece bag-making process to ensure the highest safety of wearable device batteries. In conjunction with the current mainstream smart ring solution, the bi-directional pole lugs are exported, shrinking the positive seals of the pole lugs and maximizing the use of the product's effective space, thus realizing the goal of maximizing the battery's capacity!
