The three by four battery mentioned above is a lead acid battery. The 54.7 volt lithium battery has 13 strings, and the 58.8 volt lithium battery has 14 strings. With one more string, the tension is higher and. the corresponding power is higher, both are used with 48V electric vehicles, you can use either one. Generally those with larger capacity are 58.8V.
No, if you use 9.5 or 9.6V you need to charge it. If you continue to use it, it will cause excessive discharge and the battery will be discarded. If it is a battery with a protection device, it will be difficult to discharge the power if it is lower than 9.5V.
Since the 11.1V battery is made of three 3.7V lithium batteries connected in series, the upper charging voltage of the 3.7V battery is 4, 2 V and the discharge cut-off voltage is 3 V. It isThis is a theoretical statement, but. in practice, it will be full when charged to 4.17 V and 4.18 V, and it will be discharged when discharged between 3.2 and 3.3 V. After being discharged, it will return to approximately 3.4 V after a period of 3.4 V. time.
To put it simply, it should be charged when it reaches around 9.6V, and it is fully charged when it reaches around 12.5V
