For us, these batteries are used in large numbers in radio-controlled toys, especially in RC boats and cars, both for the drive, as well as ancillary units and the remote control (transmitter and receiver) and beyond regularly in all possible flashlights , They hold very long and with an appropriate special charger they can also be reloaded at least once almost full power. I'm using this brand, alongside Varta and SONY, for many years, because I can do not need cheap batteries due to its purpose, the leak or even explode when times are a little warmer due to the stress. Strong buy recommendation, in particular because it always "special packs" are where some bonus batteries are included.
