Detailed Description

• All-in-One Power Solution: Compact charging and protection board for single-cell ($1\text{S}$) $3.7\text{V}$ nominal ($4.2\text{V}$ peak) Li-ion/LiPo batteries (e.g., 18650, 21700).

• Smart CC/CV Charging: Powered by the TP4056 IC to deliver precise Constant-Current / Constant-Voltage charging for maximum battery safety and lifespan.

• Dual Protection Suite: Integrated DW01A safety IC and 8205A dual MOSFET array shield against overcharge ($>4.25\text{V}$), deep discharge ($<2.5\text{V}$), overcurrent ($>3\text{A}$), and short circuits.

• Modern Type-C Port: High-durability USB Type-C input allows seamless power delivery from standard smartphone chargers and power banks.

Key Features

• Integrated safety circuitry protecting against overcharge, over-discharge, short circuit, and load overcurrent

• Standard $1\text{A}$ charge rate out of the box (adjustable via RPROG​ resistor modification)

• Dual LED status indicators for active charging ($Red$) and charge complete ($Blue/Green$)

• Dedicated load outputs ($OUT+/OUT-$) to power external circuits while maintaining battery protection

• Flexible input options featuring both USB Type-C port and direct solder pads ($IN+/IN-$)

Technical Specifications

How to Use

1. Connect battery positive to $B+$ and negative to $B-$ (connect battery before load)

2. Connect load/circuit wires to $OUT+$ (positive) and $OUT-$ (negative)

3. Plug a Type-C cable into the port or apply $5\text{V DC}$ across $IN+$ and $IN-$

4. Monitor LEDs ($Red$ indicates charging in progress; $Blue/Green$ indicates full charge at $4.2\text{V}$)

SAFETY NOTICE: Avoid pulling more than $2\text{A}-3\text{A}$ continuous current from $OUT+/OUT-$ to prevent tripping the overcurrent protection.
