Separation of all the housing, the electrically small the power box M10400B mobile power internal batteries and circuit boards to show in our eyes, previously has been mentioned internal use four 18650 batteries as a power storage unit boardseparable two-layer circuit board design, the top-level functional version of the six blue LED, and lower the main circuit board.
Electric the Primary Two the power box M10400B mobile power circuit board is very structured for JIAYU G4, the overall work more outstanding performance, four-core power-saving circuit board at close proximity also use a layer of insulating paper design, electrodes of the batteries and circuit boards and wires to isolate. The entire circuit board integrated master circuit, charging circuit and battery protection circuit.
