Suitable Battery Types
This charger module is intended for single-cell lithium batteries, such as:
• 1 × 18650 3.7V battery
• 1 × 14500 lithium battery
• Single-cell LiPo battery
• Other compatible 1S 3.7V lithium-ion cells
⚠️ Multiple cells may only be connected in parallel if properly matched and safely configured.
⚠️ Do not use this module to directly charge a 2S, 3S or higher-series lithium battery pack.
Important 1A Charging Current Note
The module is commonly configured for approximately 1A maximum charging current.
However, not every lithium battery should be charged at 1A.
For small-capacity cells, a lower charging current may be required.
Always check the battery manufacturer’s recommended charging current before use.
Protection Circuit Advantage
Unlike basic charger-only versions, this board includes a protection stage.
This helps protect the battery against:
✅ Excessive charging voltage
✅ Excessive battery discharge
✅ Excessive output current
✅ Short-circuit conditions
For projects using the battery to power a load, connect the load to OUT+ and OUT−, rather than directly across B+ and B−, to benefit from the protection circuit.
Why Choose Type-C Version?
The USB Type-C connector makes this module easier to use with modern chargers and cables compared with older Micro-USB charging boards.
USB Type-C থাকার কারণে modern charger এবং cable ব্যবহার করে battery charge করা সহজ হয়। Portable electronics, robotics এবং rechargeable DIY project-এর জন্য এটি খুব convenient solution।
Important Notes / গুরুত্বপূর্ণ নোট
⚠️ Designed for 1S lithium battery only.
⚠️ Input voltage should be approximately 5V DC.
⚠️ Do not apply 9V, 12V or other fast-charger voltage directly unless the charger is operating in standard 5V mode.
⚠️ Battery polarity must be connected correctly.
⚠️ Reverse battery connection can damage the module.
⚠️ Maximum charge current is approximately 1A, but actual current depends on battery state, temperature and supply capability.
⚠️ Module may become warm during charging; provide ventilation.
⚠️ Do not use damaged, swollen or unsafe lithium batteries.
⚠️ This module is not a step-up converter; battery output remains around the battery voltage range.
⚠️ For projects that must operate continuously while charging, a proper power-path/load-sharing circuit may be preferable.
⚠️ PCB layout, LED color and component markings may vary slightly depending on stock batch.
