TP45056 1A L-ion battery charging module:

Here are some key points you might find in a typical Li-ion battery charging module:

1. Input Voltage:
   • Charging modules usually operate on a specific input voltage. This can vary, but common configurations include 5V USB input or higher voltage inputs for larger batteries.
2. Charging Current:
   • The charging current is the amount of current supplied to the battery during the charging process. Modules often have a fixed charging current, and it can be specified on the module. For example, "1A" indicates a charging current of 1 ampere.
3. Charging Indicator:
   • Many charging modules include LEDs or indicators to show the charging status. This can include an indication of whether the battery is charging or fully charged.
4. Protection Features:
   • Charging modules may incorporate protection features such as overcharge protection, over-discharge protection, and short-circuit protection to ensure the safety of the battery.
5. Compatibility:
   • Modules may be designed for specific battery chemistries, such as lithium-ion or lithium-polymer. It's important to use a module that is compatible with the type of battery you are charging.
