What is a 36V LiFePO4 battery pack?
A 36V LiFePO4 battery pack is usually composed of twelve 3.2V cells connected in series, resulting in a total nominal voltage of 38.4V. Charging to 43.8V indicates that the battery pack is fully charged, and each cell reaches 3.65V at this moment. Discharging to 30V means that the battery pack has been fully discharged, with each cell at 2.5V.
How many Mah can be assembled into a battery pack?

How many volts is a lithium polymer battery?
Single lithium polymer (Li-Po) cells typically have a nominal voltage of 3.7 volts. When the voltage of this type of cell is charged to 4.2 volts, it is considered fully charged. During the battery discharge process, when the voltage drops to 3.27 volts, the battery is considered fully discharged.
What is the relationship between voltage and soc in lithium polymer batteries?
During the charging and discharging process of lithium polymer (Li-Po) batteries, the relationship between voltage and SOC (State of Charge) exhibits clear nonlinear characteristics. Especially when the battery is approaching full charge or discharge, the voltage changes more rapidly.
How many volts is a LiPo cell battery?
1. A fully charged lipo voltage is 4.2V per cell (HV lipo can be charged to 4.35V). 2. A lipo cell battery should never be discharged below 3.0V. 3. The proper lipo storage voltage is 3.8V per cell. 4. A lipo cell nominal voltage is 3.7V. Relationship of Voltage and Capacity Above show you the relationship of voltage and capacity from Rcgroups.
