Product Overview

The Shutao TP5100 charging board is engineered to meet the demanding power requirements of modern portable electronics, robotics, and hobbyist projects. Built around a robust switching regulator architecture, the module accepts a wide input voltage range of 5 to 18 volts and delivers a steady 2 ampere output, making it suitable for both single‑cell 4.2 V and dual‑cell 8.4 V lithium‑ion batteries. Its compact dimensions of 0.2 × 3 × 4 inches and lightweight construction (0.48 oz) allow seamless integration into tight enclosures, while the board’s copper‑clad PCB ensures reliable thermal dissipation during continuous operation.

Beyond basic voltage regulation, the TP5100 incorporates a sophisticated three‑stage charging algorithm that begins with a gentle trickle pre‑charge, progresses to a constant‑current phase, and finishes with a constant‑voltage termination to maximize battery lifespan. Integrated safety features include temperature monitoring, over‑current detection, undervoltage lockout, reverse‑polarity shutdown, and short‑circuit protection, all of which work together to safeguard both the battery pack and the host device. The board’s design follows industry‑standard footprints, enabling straightforward solder‑on installation without the need for additional connectors or external components.

Manufactured by Shutao, a reputable supplier in the industrial and scientific sector, the TP5100 has earned a solid reputation for reliability, as reflected in its 5‑star customer rating on major e‑commerce platforms. The module is compliant with RoHS standards, ensuring that it is free from hazardous substances and suitable for environmentally conscious applications. Whether you are developing a custom robot arm, a handheld power tool, or a portable communication device, the TP5100 provides a dependable power‑management foundation that can be trusted to perform under a variety of operating conditions.

Usage

Robotics enthusiasts will find the TP5100 especially valuable when powering autonomous platforms that require precise battery management. The board’s ability to handle both 4.2 V and 8.4 V configurations means it can be paired with a single cell for lightweight drones or a dual‑cell pack for larger ground‑based robots, delivering consistent power while protecting the cells from over‑charging and thermal runaway. Its small footprint allows it to be mounted directly onto a robot’s control board, reducing wiring complexity and improving overall system reliability.

In addition to robotics, the TP5100 excels in portable tool applications such as cordless drills, electric screwdrivers, and handheld laser cutters. The 2 A output is sufficient to charge high‑drain lithium batteries quickly, while the built‑in protection circuitry prevents damage caused by sudden load spikes or accidental short circuits. The board’s wide input voltage tolerance also enables it to be powered from a variety of sources, including solar panels, car adapters, or standard USB power supplies, giving designers flexibility in choosing the most appropriate energy source for their product.

DIY hobbyists and makers can integrate the TP5100 into custom charging stations for smartphones, tablets, and other consumer electronics. Its straightforward pin layout—comprising input, output, and status LEDs—makes prototyping simple, and the module can be combined with additional monitoring circuitry to create smart chargers that report battery health via Bluetooth or Wi‑Fi. The board’s low cost and high reliability make it an attractive choice for educational kits, maker fairs, and small‑scale production runs where performance cannot be compromised.

FAQ

What input voltage range can the TP5100 handle?

The TP5100 is designed to operate from a 5 V to 18 V DC input. In practice, a 5 V to 12 V supply provides the most efficient charging performance for typical lithium‑ion cells, while higher voltages are supported for applications that require additional headroom.

Can the board charge both single‑cell and dual‑cell batteries?

Yes. The module automatically adjusts its charging profile based on the connected battery configuration. For a single 4.2 V cell, it delivers the appropriate constant‑current and constant‑voltage phases. When a dual‑cell 8.4 V pack is attached, the board scales its output to match the higher voltage while preserving the same safety and efficiency features.

Is the TP5100 suitable for high‑drain applications like power tools?

Absolutely. The 2 A current rating, combined with robust thermal management and over‑current protection, makes the TP5100 capable of handling the intermittent high‑draw demands typical of cordless power tools. The board’s protective circuitry will limit current spikes to safe levels, preventing damage to both the battery and the tool.

How does the temperature protection work?

The board includes an integrated temperature sensor that monitors the ambient and component temperature during operation. If the temperature exceeds the predefined safe threshold, the regulator automatically reduces the charging current or shuts down the output to prevent overheating, thereby extending battery life and ensuring user safety.

What kind of support does Shutao provide after purchase?

Shutao offers a comprehensive support package that includes detailed datasheets, reference schematics, and application notes. Customers can also access a dedicated technical support line and online forum where engineers can ask questions, request firmware updates, and receive guidance on optimal board integration.
