DIY Powerbank LCD Case Modul Enclosure Casing Power Bank 8x 18650 2.1A - Merah

The housing size is 171*80*22MM, and the battery size is 145*66*18MM.

Input: Old version: 5V2.1A (MAX)

      New version: 5V2.4A (up to 2.8A)

Output: Legacy: 5V2.1A (MAX)

      New version: 5V2.1A ( MAX )

Button function: old version: double-click to turn off the flashlight, long press to close the output

          New version: long press to turn off the flashlight, double click to close the output

Display mode: Old version: Output 5V1A/2A is only used to identify the output port, can not know the current size; input IN flash, less than 1A display 1A; higher than 1A display 2A.

          New version: The output is displayed according to the device current, which distinguishes the current. The output current is greater than 1A to display 2A output, the output current is less than 1A to display 1A output; input IN flash.

Adoption plan: old version: software + three in one

          Advantages: high starting current and high voltage

          Disadvantages: poor recognition, below 0.2A may not be able to output normally, conversion rate is general, need to activate to have output.

          New version: software + MCU microcontroller

          Advantages: Synchronous rectification switch scheme, no activation, high conversion rate, strong recognition ability, can support 0.05A small current equipment

          Disadvantages: Since the MCU pin is not enough, the input only has an IN flash.

Power calculation method: old version: Coulomb calculation method, need to be fully charged and charged once accurately

             The new version: Coulomb + voltage algorithm; with the charge, do not need to fully charge and discharge.

          Common shortcomings: When the battery performance is poor, the voltage drops too fast to 3V, it will immediately become 00, even after the standby, the battery voltage will go back, the power will not rise back, so it is not recommended to use the internal resistance, long time, A battery that has been used many times.
