3.2V200AH Lithium Battery

Basic parameters

Voltage: The nominal voltage is 3.2V, the charging limit voltage is generally around 3.65V, and the discharging limit voltage is usually not less than 2.5V

Capacity: 200Ah indicates that under certain discharge conditions, the total amount of electricity that the battery cell can release is 200 ampere hours. Calculated at a nominal voltage of 3.2V, the total energy stored is approximately 640 watt hours

Size: The size of 3.2V 200Ah lithium battery cells produced by different manufacturers may vary slightly. Taking the honeycomb lithium iron 184A lithium battery module as an example, the individual cell size is about 2.2cm thick, 11.8cm wide, and 58.6cm high

Weight: Generally, the weight of a single unit is about 3.4kg

Performance characteristics

Energy density: Lithium batteries have a high energy density, with 3.2V 200Ah lithium cells generally having an energy density between 100-200Wh/kg. Compared to traditional lead-acid batteries, they can store more electrical energy at the same volume and weight, providing longer power support for devices

Charging and discharging efficiency: Charging time may vary depending on the charging current and charger performance. Generally, a charging rate of around 0.5C is used, and the charging time is about 2-3 hours. The discharge efficiency is relatively high, and under normal usage conditions, it can output a relatively stable current to meet the electrical needs of the equipment

Cycle life: Under appropriate charging and discharging conditions, the cycle life can reach over 2000 times. For example, at a 1C charge discharge rate, the cycle life of lithium iron phosphate batteries is relatively excellent, and after multiple charge discharge cycles, they can still maintain a high capacity retention rate

Self discharge rate: The self discharge rate is relatively low, and when stored at room temperature, the monthly self discharge rate is generally around 5% -10%, which is better than traditional nickel hydrogen batteries and nickel cadmium batteries
