LiPo Battery Charging Module 2A (TP5100)

LiPo Battery Charging Module 2A (TP5100) – Product Overview

The LiPo Battery Charging Module 2A (TP5100) is a compact, high-efficiency charger designed specifically for lithium polymer batteries. Engineered for fast, safe charging, the TP5100 is ideal for hobbyists, makers, and product designers who need reliable charging for single-cell (3.7V) and dual-cell (7.4V) LiPo packs.

Key Benefits

• Fast charging up to 2A reduces downtime for battery-powered projects.
• Wide 5V to 18V input range supports USB sources, DC adapters, and solar panels.
• Integrated protections preserve battery life and prevent damage during charging.
• Small form factor allows seamless integration into portable electronics, drones, and DIY systems.

Features of the TP5100 LiPo Battery Charging Module

High-Performance Charging

The TP5100 module delivers up to 2A of charge current using a two-stage CC/CV charging algorithm. In Constant Current (CC) mode it supplies a steady charge current until the cell voltage reaches the target threshold; it then switches to Constant Voltage (CV) mode to top the battery off safely.

Wide Input Voltage Compatibility

Operate the module from a variety of power sources thanks to its 5V to 18V DC input range. This makes the TP5100 suitable for USB powerbanks, wall adapters, bench supplies, and small solar setups.

Battery Compatibility

• Single-cell LiPo: nominal 3.7V
• Dual-cell LiPo: nominal 7.4V

Comprehensive Protection Features

Safety is built in. The module includes:

• Overcharge protection to prevent battery damage when full
• Over-discharge protection to avoid deep discharge
• Short-circuit protection to protect both the battery and the module
• Thermal protection to reduce charge current or shut down if temperatures rise

Status Indicators

Simple LED feedback shows charging and fully charged states, making it easy to monitor progress at a glance during development or field use.
