Different voltages have different capacitance values.
1. From the perspective of capacity value, according to the query on iAsk Knowledge Network, the capacity value of each string of lithium batteries is the same, and the capacity of each string is 2500 mAh. The 6-string lithium battery has 15,000 mAh and the 6-string lithium battery has 17,500 mAh.
2. From a voltage perspective, according to the Query Analysis Testing Encyclopedia website, 6 strings of full power is equal to 22.2 volts and 7 strings of full power is equal to 25.9 volts.
The 12v-50ah lithium battery represents: the battery works at 50A current on a device with a voltage of 12V and can work for 1 hour.
Ampere-hours (AH) represent the size of the battery capacity. For batteries of the same voltage, the one with the greater amp-hour has a greater capacity; for batteries with the same amp-hour, the one with the higher voltage has a greater capacity. Battery capacity is usually expressed in terms of voltage and amp hours. hours.

Lithium battery characteristics:
1. High energy density
The weight of lithium-ion batteries is half that of nickel-cadmium or nickel-hydrogen batteries of the same capacity, and the volume is 20-30% nickel- cadmium and 35 -50% nickel-hydrogen.
2. High voltage
The operating voltage of a lithium-ion battery cell is 3.7 V (on average), which is equivalent to three connected nickel-cadmium or nickel-metal hydride batteries. serial.
3. Pollution-free
Lithium-ion batteries do not contain harmful metal substances such as cadmium, lead and mercury.
4. Does not contain metallic lithium
Batteries haveLithium-ion batteries do not contain metallic lithium, so they are not restricted by air transport regulations such as the ban on carrying lithium batteries on board passengers. plane.
5. High service life
Under normal conditions, the charge and discharge cycles of lithium-ion batteries can exceed 500 times, and lithium iron phosphate (hereinafter referred to as iron phosphate) can reach 2,000 second rate.
6. No memory effect
The memory effect refers to the phenomenon that the battery capacity decreases during the charge and discharge cycle of nickel-cadmium batteries. This effect does not exist with lithium-ion batteries.
7. Fast charging
Using a constant current and constant voltage charger with a rated voltage of 4.2V, the lithium-ion battery can be fully charged in 1.5-2.5 hours; and The new lithium iron battery phosphate can be fully charged in 35 minutes.
