Product Description
This small module is designed to charge single-cell 3.6/3.7V lithium-ion batteries using a mini USB cable or a separate 5V PSU. The module is based upon the TP4056 single chip Li-on charger and delivers a maximum charge rate of 1 Amp.
The charge current can be reduced by modifying the RProg resistor: –
| RProg Resistor | Charge Current (mA) |
| 10K | 130 |
| 5K | 250 |
| 4K | 300 |
| 3K | 400 |
| 2K | 580 |
| 1K6 | 690 |
| 1K5 | 780 |
| 1K3 | 900 |
| 1K2 | 1000 (default) |
The module has two LED indicators, red for charging and Green for fully charged.
Warning: This unit is not protected against an incorrectly connected Li-on battery – Please double check the polarity before connection.
