Built in intelligent buck boost circuit, compatible with multiple voltage input and output scenarios, and adaptable to various devices3. Bi directional charging and discharging of lithium batteries, suitable for applications such as mobile power banks and energy storage systems4. Intelligent recognition device requirements, safe and efficient matching of charging current and voltage5. Accurately match the working voltage range of the battery to ensure charging and discharging safety and battery lifeProduct ParametersType C interface: PD100W 20V5AUSB port: SCP22.5W 4.5V5A, 18W/20W 9V2AElectricity percentage displayInterface current and voltage displayNotes:1. Do not perform live welding, which means that when welding the+- two wires of the motherboard, these two wires are not powered, which can avoid 99.99% of unexpected situations.2. The motherboard only has+-, and if it is soldered with power on, it may shake and burn easily. Please turn off the power and solder it first. Connect the motherboard+- first. The negative electrode of the battery pack is finally welded!!! The two wires on the motherboard cannot balance the battery, and the balance protection function is on the lithium battery protection board.3. The first power on may not display the battery level correctly, but it will return to normal after cycling.4. The default capacity of a single 500mah may vary greatly, but the battery display may not be accurate. It does not affect other functions and there is no need to worry about overcharging or discharging.Packing ListModule * 1GABA0090-002/GABA0090-003 Low end versionProduct Features1.20V/5A strong output, supports high-speed charging and discharging, higher efficiency2.

Protection board wiring, 4S battery pack, starting from the negative pole, the first positive pole is b1, with a voltage of 4.2V (3.6V for lithium iron). Then b2 is 8.4V, b3 is 12.6V, and b+is the positive pole 16.8V. The p+p of the protection board is connected to the main board.2. If the battery is charged but does not light up or work after being connected, please charge and activate the C port first. The battery needs to be charged and activated regardless of whether or not it is charged.3. After charging activation, it displays 0 or 100. The battery level cannot be accurately displayed during the first power on, and it returns to normal after charging and discharging cycles.4. During use, when charged to 80, it cannot be fully charged, and when discharged to 20, it will break. This is caused by inconsistent voltage. The most serious situation is that if the battery is fully charged at 4.2V but below 3V, it cannot be used anymore.Precautions1. Please turn off the power for welding, first connect the motherboard+-, and finally weld the negative terminal of the battery pack2. The two wires on the motherboard cannot balance the battery. The balance protection function is on the protection board, and an additional lithium battery protection board can be addedPacking list:Module * 1
