The 12V lithium battery is a combination of lithium batteries. Multiple single lithium batteries are connected in series to become a dual-use battery and backup power supply. It is also often used in everyday life. For example, many motorcycle batteries are 12V, and the DC voltage of cars is also mainly 12V.
_Fei Jue Shi Mi Zhen Noisy Niu Kai is 500 times charged and discharged between 0% and 100%. If it is between 10% and 90%, the lifespan will exceed 500, reach 700 or even 1000. 20% to 80% is even higher, or even more than 2000 times.
There is a corresponding nonlinear relationship between DOD depth and lifetime. If the depth is reduced a little, the service life will be greatly extended. In other words, if it is not full or discharged, the lifespan. will be long.
Find a pointbalance between capacity and service life, generally 500 times, which is basically enough. If ultra-long life is required, such as for satellites, the DOD depth must be reduced to sacrifice ultra-long life capability. -long life. . If you need very large capacity, you can increase the DOD, or even exceed it, in exchange for high performance, such as in various competitions.
3 cells 12.6 V, 4 strings 16.8 V. Floating charge. Refers to recharging when working online. This method is often used in emergency power situations. It cannot be charged if it is lower than 12 volts and it will affect the operation of the circuit if it is too high. Therefore, when floating charging is working, the voltage is 13.8 volts.
Main principles
1. Lithium battery: It adopts plastic winding structurespiral and uses very thin, highly permeable polyethylene film insulation material to separate the positive and negative electrodes.
2. Dry battery: the carbon rod is used as the positive electrode and the zinc cylinder is used as the negative electrode, which converts chemical energy into electrical energy and supplies it to the external circuit. In chemical reactions, because zinc is more active than manganese, zinc loses electrons and becomes oxidized, while manganese gains electrons and is reduced.
