To do that, two thin aluminum or copper plates are used (one for negative and one for positive connectors) to connect all the batteries with the power bank circuit boards. Most power bank manufacturers avoid using wires and prefer these metal plates, which are a crucial part of a power bank.
Connect the DC+ and DC- cables to the DC+ and DC- terminals. Connect the power cables in the UPS. If more battery cabinets are part of the solution, connect all battery cabinets to the UPS according to the diagram below.
A power bank circuit board is responsible for making a power bank work. It acts as a central mediator between the batteries and your mobile phone. Therefore, power bank circuit board is the most crucial part of the power bank. What’s inside a power bank? Below is the list of what you’ll find in a power bank.
Connect the power bank to a power source and charge the batteries for a few hours. Then connect your smartphone to the USB output, and check if the phone starts charging. After the tests and trials succeed, you’ll have to get in touch with a plastic molding company, who can create bodies for your power bank circuit board and battery.
Wire Type: Use stranded wire for flexibility, especially in tight spaces. Gauge (AWG): 22–24 AWG is usually good for power banks. Lower AWG = thicker wire = more current. Connectors (Optional): For switches, LEDs, or modular battery packs. Make sure they match your wire gauge and current needs.
Protected batteries come with built-in safety circuits, known as protection circuit board (PCB). If you use unprotected ones, your charging board must handle safety features like overcharge protection. The charging board manages battery charging and controls the power flow to your devices. It usually includes:
