21.8v
tv means the nominal voltage of the battery is v, lithium battery 218tv, because t means approximately negative minus 10v, so 218 divided by 10 is equal to 21.8. The voltage of this set of lithium batteries is 21.8 V. The batteries in the 128tv are 128 volts.
A battery refers to a cup, tank or other container or part of a composite container containing an electrolyte solution and metal electrodes to generate electric current. It is a device capable of converting chemical energy into electrical energy. It has positive and negative poles. With the advancement of technology, batteries generally refer to small devices capable of producing electricity. Like solar cells. Battery performance parameters mainly include electromotive force, capacity, specific energy and resistance. Usingbattery as a power source, you can get power with stable voltage, stable current, stable power supply for a long time and little influence from the outside world. The battery has a simple structure and is easy to carry.
59V. v means volts, which is the unit of voltage; and t means negative minus 10 V. For example: a 980 tV battery is equal to 98 V, because t is roughly negative 10 V, so the voltage of this lithium battery set is 98 volts. In other words, the 598tV battery cell is 59 V, because t is approximately negative 10 V, so the voltage of this lithium battery pack is 59 volts.
