The 12V Uninterruptible Power Supply (UPS) Module with Dual 18650 Battery Slots is a high-efficiency backup power management board designed to keep 12V hardware running seamlessly during blackouts. Operating at a high capacity of 15W, this module features a modern USB Type-C port for primary power input and steps up energy efficiently to deliver a continuous, regulated 12V output at the UPS+ / UPS- terminals. It features a dual onboard 18650 battery holder that charges the cells during normal operation while providing instantaneous, glitch-free fallback power the millisecond mains power drops—making it the ideal solution for Wi-Fi routers, smart home hubs, and modems.
Product Overview
The 12V 15W Uninterruptible Power Supply (UPS) Module with Dual 18650 Battery Slots is an advanced, high-efficiency power management breakout board engineered to safeguard your sensitive 12V electronics from sudden electrical failures, load shedding, and blackouts. This intelligent circuit board handles charging and voltage boosting in a single unit. It sits directly between a standard USB power source and your target equipment, managing two rechargeable lithium-ion cells to provide instantaneous, glitch-free backup electricity without causing hardware reboots or system drops.
Advanced Charging & Boost Architecture
- High-Efficiency 15W Boost Engine: The layout integrates a high-speed synchronous step-up converter centered around a low-loss 2R2 power inductor and heavy-duty SS54 Schottky diodes. This power block efficiently multiplies the nominal 3.7V battery voltage up to a rock-solid, regulated 12V DC output, capable of delivering up to 1.2A of continuous current.
- Integrated Dual 18650 Battery Slots: Built directly into the underside and top edges of the PCB is a heavy-duty, spring-assisted dual 18650 lithium-ion cell holder. This setup handles two cells in a parallel layout, significantly expanding your total energy capacity (amp-hours) for longer backup runtimes.
- Modern Type-C & Solder Inputs: Equipped with a robust USB Type-C port for tool-free, everyday power input from standard phone chargers. For advanced permanent installations, it features flanking
5V+and5V-input solder pads, letting you hardwire a dedicated 5V power supply directly. - Multi-Stage Smoothing Filters: Populated with multiple low-ESR solid aluminum capacitors (220µF 16V VT), the board irons out conversion noise and suppresses transient voltage spikes, ensuring clean linear current flows straight to your connected devices.
Smart Charging Logic & Safety Features
The module features a highly automated dual-chip control topology that handles complex power-path routing seamlessly:
- True Uninterruptible Power Pathing: During normal grid operations, the board passes power from the Type-C input directly to the 12V output while simultaneously topping off the 18650 batteries. The exact millisecond the external input cuts out, the internal logic switches paths to draw power from the batteries instantly, ensuring your equipment never experiences a power gap.
- Comprehensive Battery Safety Net: The board features built-in protection circuitry to monitor the health of your lithium cells continuously, including over-charge protection, over-discharge cutoff (safely cutting off current before cells drop below 2.8V), and short-circuit isolation.
- Configurable Charge Currents: Features a customizable hardware jumper layout on the PCB surface. By opening or bridging specific programming traces, builders can throttle the charge current between 0.6A and 1.2A to optimize performance based on their power adapter’s maximum limits.
Symmetrical Output Terminal Layout
The front edge of the green-mask PCB features oversized, gold-plated solder terminals designed for quick, robust wiring:
UPS+/UPS-: Dedicated backup-regulated 12V output lanes that connect directly to your target router, modem, or camera gear.StateSignal Pads: Integrated hardware logic pads that output high/low states, allowing advanced builders to wire external warning LEDs or link the module to an Arduino to track if the system is currently running on battery or grid power.
Common Field Applications
- Continuous Wi-Fi & Internet Rigs: Keeping home Wi-Fi routers, fiber optic modems (ONUs), and network switches active during localized load shedding to prevent internet disconnections.
- CCTV & Security Backup: Maintaining constant recording and network streaming on 12V IP security cameras and digital video recorders (DVRs) when external lines fail.
- Smart Home Hub Automation: Powering central smart gateways, automated electronic door locks, and wireless alarm bridges continuously.
- Portable Engineering Stations: Providing a highly compact, self-contained 12V field testing supply rail for mobile electronics debugging, sensor grids, and remote IoT nodes.
