First of all, we need to clarify the concept: for a 12v10ah lithium battery, 10ah is the battery capacity, not the battery discharge current. The 12v14ah protection board must be a 14A protection board. 14A refers to the maximum operating current of the protection board.
So its use depends on your needs, or whether the 14A current is enough for charging, and whether the battery output capacity matches.

The composition of lithium batteries
Lithium batteries rely primarily on the movement of lithium ions between positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates between the two electrodes. The material of the positive electrode is mainly lithium active material, which is generally lithium manganate or lithium cobalt oxide, a materiallithium-nickel-cobalt manganate (commonly known as ternary), lithium iron phosphate and other active lithium compounds. The main negative electrode material is lithium-carbon interlayer compound LiXC6, which is basically a carbon material with good performance and chemical stability, such as graphite, carbon fiber, glassy carbon, etc. In terms of negative electrode materials, graphene due to its excellent charging and discharging performance, it has attracted more and more attention from various lithium battery manufacturers and investment institutions. The electrolyte is usually a carbonate solvent in which lithium hexafluorophosphate is dissolved, while the polymer electrolyte uses a gel electrolyte. Since the electrolyte uses an organic solvent, the conductivity is very low. This makes the self-discharge of lithium batteries very low. Allows electric current chargingevéd during charging. Therefore, the general charge of lithium batteries can reach 1C.

I want to assemble a 12V80a lithium iron phosphate battery to use as a power supply, using the soft silver white parts type
The 12v-50ah lithium battery represents: The battery operates 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.
Detailed information:
1. High energy density
The weight of lithium-ion batteries is half that of nickel-cadmium or nickel-metal hydride batteries of the same capacity. , and the volume is 20 times that of nickel-cadmium batteries -30%, 35-50% NiMH.
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 lithium metal
Lithium-ion batteries do not contain lithium metal, so they are not restricted by air transport regulations such as the ban on transporting lithium batteries on board passengers. plane.
5, Long service life
Under normal conditions, the charge and discharge cycles of lithium-ion batteries can exceed 500 times, and lithium iron phosphate (ci -after called iron phosphate) can reach 2,000 times.
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 phosphate battery can be fully charged in 35 minutes.
