Key Product Features
- 22.5W Dual-Way Turbo Charging: Eliminates slow power bank refills. The bi-directional USB-C port charges the connected smartphone quickly and accepts high-wattage input power to replenish the main battery pack in a fraction of the time.
- Massive Multi-Port Matrix Layout: Hosts five strategic port blocks on a single slender layout. The green-shrouded dual USB-A terminals give you dedicated high-current output lanes, while the input collection lets you recharge the bank using standard Android or Apple cables.
- Advanced NTC Thermal Safetynet: Features a pre-wired external NTC probe wire. Taping this tiny thermal bead directly onto your lithium cells ensures the main power management chip scales back or stops current delivery if temperatures exceed safe limits during high-amp operation.
- Solder-Ready Heavy Duty Terminals: Designed with oversized, gold-flashed B+ (Battery Positive) and B- (Battery Negative) solder pads on opposite edges of the PCB substrate, ensuring thick gauge wiring can safely carry up to 5A to 6A of charging current.
- Synchronous Rectification Logic: Uses an integrated synchronous buck-boost converter loop coupled with a 2R2 power inductor. This achieves up to 95% efficiency, reducing board heat generation and saving cell power from being lost as waste heat.
Critical Assembly & Wiring Safety Guide
Because custom lithium battery configurations require careful assembly, include these safety protocols on your product listing to prevent user errors:
- Cell Layout Restriction: You must connect multiple lithium cells strictly in Parallel configuration to expand the capacity (Ah) while keeping the base voltage at 3.7V Nominal (4.2V fully charged). Never wire cells in series (such as 2S, 3S, or 4S), as introducing 7.4V or higher to the B+/B- terminals will instantly destroy the logic components.
- First-Time Activation Process: When you solder your battery pack to the board for the first time, the board will initially enter a safety standby lockout mode. To wake and activate the circuit, simply plug a live 5V charging cable into the Type-C or Micro-USB port for 3 to 5 seconds.
- Polarity Warning: Double-check your wire connections before soldering. Reversing the positive and negative leads on the B+ and B- pads will instantly burn out the power tracking ICs.
