LiPo (lithium polymer) batteries, especially cars, ships, etc. .. many models used in the cells are 3.7v because three or more coupled in series to the proper voltage is being achieved most widely used package 12V ones for this three lithium-polymer lipo battery series is connected but in series of batteries balanced charging required for this balance or balancing charge are circuits this circuit is in addition to battery voltage condition used to monitor connected to the batteries any 3v falls under the circuit buzzer sound is giving.
