TP4056 Lithium Charging Board with Protection — 5V 1A
The TP4056 Charging Board with Dual Protection adds over-discharge and over-current protection to the standard TP4056 charger — essential for safely using 18650 cells and other unprotected lithium batteries. The DW01A + 8205A protection ICs cut off the battery if voltage drops below ~2.5V or if current exceeds safe limits.

|---|---|
| Protection | DW01A + 8205A (over-charge, over-discharge, over-current) |
| Input | Micro USB (5V) |
| Charge current | 1A |
