- DIY Bluetooth speaker with rechargeable battery
- Solar-powered charger when paired with a 5V solar panel
Compatibility
This module is designed for single-cell lithium-ion or lithium-polymer batteries with a nominal voltage of 3.7V, such as 18650, 14500, or pouch cells. It works with any standard 5V USB source and can also be powered via the IN+ and IN- pads. The output voltage follows the battery voltage and is not regulated; for a stable 5V output, pair it with a boost converter like the MT3608.
Wiring Notes
Connect the battery to B+ (positive) and B- (negative) terminals, ensuring correct polarity. Power input is through the micro USB port or the IN pads; do not exceed 5.5V. The module includes a DW01A protection IC, so you can safely leave the battery connected during charging. For continuous load operation, consider using a load-sharing circuit.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with 18650 batteries?
Yes, the TP4056 module is specifically designed for single-cell lithium-ion batteries like 18650 cells. Just ensure your battery is not deeply discharged below 2.5V before connecting.
Does this module provide battery protection?
Yes, most TP4056 modules, including this one, include the DW01A protection IC that prevents over-discharge, over-current, and short circuits, making them safe for permanent battery connections.
Can I charge and use the battery at the same time?
The TP4056 alone does not support simultaneous charge and discharge safely. To power a load while charging, you'll need a load-sharing circuit or a dedicated charger module with that feature.
