In general, this is not possible. If you bring a skid plate, you can use it in an emergency. It will be full of natural protection and will stop charging.
18650 has large capacity and high voltage, generally 3.7V2200mAh, and 14500 iron phosphate battery has 3.2V600mAh. Charging current and voltage vary greatly. It cannot be used directly without a protective plate.
If the battery becomes very hot, stop charging it immediately and cannot use this charger.
Performance comparison between lithium iron phosphate batteries and lithium batteries
3.7V is about 1500-1600mA, which is normal. The 14500 lithium battery is 3.7V and has approximately 1500-1600mAh. The short circuit current should depend on the state of the short circuit and the internal resistance. If the internal resistance is 0.03 ohms, the short circuit currentis 133 A. If the internal resistance is lower, the short circuit current becomes greater. The battery is damaged due to heat.
The performance of lithium batteries is better and the capacity of lithium batteries is large, 14,500 is generally equivalent to 800 mAh, 14,500 lithium iron phosphate generally equals 600 mAh, plus the 3.6 V standard of lithium batteries. Depending on the voltage, the total discharge energy is nearly 150% of that of lithium iron phosphate. The voltage is close to 3V, which makes it easier to use. Lithium iron phosphate has good resistance to overcharge and overdischarge and generally does not require a protective plate when used in a single section.
Principle and structure of lithium iron phosphate battery:
1. Commercial lithium iron phosphate battery generally consists of the following elementsants: positive electrode material (lithium iron phosphate), negative electrode material (graphite), as well as aluminum foil (positive), copper foil (negative) as positive and negative current collectors, and contact tabs positive and negative electrode (i.e. current collector outputs).
2. There are also separators, electrolytes, aluminum-plastic films and battery protection plates. It adopts winding type and is made into 18650 type battery.
3. The principle is that during discharge, Li ions migrate from the negative electrode to the positive electrode; and during charging, Li ions migrate from the positive electrode to the negative electrode. .
