3.7V, 5800mAh, the maximum charging current is about 1.5A, so you need to use 5V2A charger for charging. Additionally, you should also check whether the available battery has voltage stabilization and protection circuits.
If you don't have one, just a battery. It is then preferable to install load protection. The maximum charging cut-off voltage of a 3.7V lithium battery is 4.2V. If you don't have a protection board on hand, you can temporarily use a voltage stabilization module to convert 5V to 4.2V in order to charge the battery. If the battery does not have charging protection, it should not be charged directly with 5V, as this will damage the battery.
Lithium polymer battery, also known as lithium polymer battery, is a chemical battery. Compared to previous batteries, it has the characteristicscharacteristics of high energy, miniaturization and lightness.
Lithium polymer batteries are ultra-thin and can be made into batteries of different shapes and capacities to meet the needs of certain products. The theoretical minimum thickness can reach 0.5 mm.
A general battery has three elements: a positive electrode, a negative electrode, and an electrolyte. The so-called lithium-polymer battery refers to a battery system that uses polymer materials in at least one or more of the three cells.
In lithium polymer battery systems, polymer materials are mainly used in the positive electrode and electrolyte. The positive electrode material uses conductive polymers or inorganic compounds used in general lithium-ion batteries. The negative electrode often uses lithium metal or lithium carbon interlayer compounds. The electrolyte uses solid or colloidal polymer electrolytes or organic electrolytes. Since there is no excess electrolyte in lithium polymer, it is more reliable and stable.
