Lithium Battery Board Power Supply

Uninterruptible Mobile Power: Converts single or dual rechargeable 18650 / Li-ion lithium batteries into a regulated 5V DC power supply, enabling mobile and battery-backed Raspberry Pi projects.

Onboard Smart Charging Circuitry: Integrated battery management IC supports simultaneous charging and discharging (pass-through power) via Micro-USB or USB-C input.

Dual USB Power Output: Features dual USB-A output ports (5V/ 2.1A max) for powering the main Raspberry Pi along with additional USB peripherals or external displays.

LED Power & Charge Status Indicators: Outfitted with multi-stage LED status lights indicating remaining battery capacity, active charge cycles, and power output state.

Integrated Circuit Safeguards: Includes protective circuitry against over-charging, over-discharging, over-current, and short-circuit conditions to prolong battery lifespan.

PCB & Component Construction: Built on a multi-layer FR4 fiberglass circuit board designed for efficient power conversion and heat dissipation.

Battery Polarity Caution: Always double-check positive (+) and negative (-) lithium battery orientation prior to insertion. Reverse polarity can cause circuit damage or overheating.

Thermal & Charging Safety: Charge batteries only with compatible 5V USB power sources. Avoid operating under heavy load inside tightly sealed enclosures without airflow.

Environmental Limits: Operating temperature range is 0^C to +45^C}. Keep protected from direct moisture, high humidity, and metallic conductive debris.

Ideal for Portable & Remote Pi Projects: Position as the ultimate power solution for handheld gaming consoles, mobile robots, environmental data loggers, and outdoor IoT nodes.

UPS Backup Power Pitch: Highlight its function as an Uninterruptible Power Supply (UPS) that keeps the Raspberry Pi running cleanly during power outages or line voltage drops.

Recommended Cross-Sell Add-ons: Pair with 18650 Rechargeable Li-ion Batteries, Brass Standoff Hardware Kits, and Micro-USB / USB-C Power Cables.

Universal Compatibility: Emphasize compatibility across all USB-powered dev boards, including Raspberry Pi 4B, 3B+, 3B, and Zero series.
