1S protection board (TP4056, DW01A, FS8205A)
the TP4056 companion board: DW01A + one FS8205A · 1S Li-ion · 3 A continuous, trips at about 3 A (7 ms), short circuit about 27 A (400 µs) · over-charge 4.3 V/cell (4.30 V pack), over-discharge 2.5 V/cell (2.5 V pack) · no balancing
Try it on the benchThe lab drops it on an empty bench and opens its datasheet card.

Ratings and limits
| Protection | DW01A + FS8205A |
|---|---|
| Cells | 1S Li-ion |
| Over-charge | 4.3 V per cell after 110 ms · release 4.1 V |
| Over-discharge | 2.5 V per cell after 55 ms · release: connect a charger (or the cells recover above 2.9 V) |
| Discharge current | 3 A continuous · over-current trip about 3 A after 7 ms |
| Short circuit | about 27 A · 400 µs · release: remove the load |
| MOSFET resistance | 50 mΩ (150 mV and 450 mW at 3 A) |
| Balancing | none |
| Temperature protection | none: above its continuous rating it heats, and its MOSFETs can fail shorted |
