Batteries have different sizes. Sometimes you need some small batteries, but you just have a big. Maybe you have a big battery, but you are in urgent need of some small. So we combine some small batteries and a big battery to solve the problem. You can put three small batteries into the slot on the shell of the big battery. It’s very convenient to disassemble or collect them. Furthermore, the battery shell with insulating rubber material keep a better touch. You can choose different sizes of batteries what you need at any time.
