Many customers have reported that toy walkie-talkies that only use dry batteries need to be replaced frequently, which is not environmentally friendly. Recently, we have developed a new walkie-talkie T10L with a lithium battery. The 1200MA BL-10C lithium battery can be used for more than 6 hours on a single charge. The talk distance can reach 8-10KM. It is still a license-free 0.5W walkie-talkie. 8-16-22 channels and various frequencies are optional. It can be customized for different countries and brands, which greatly meets the low-cost communication needs of families and children outdoors.
