| + | [title] About an original battery |
|---|---|
| + | [* black] An original 3.7V battery consists of two batteries stitched together in parallel and a protection board |
| + | [* black] Protection board itself has two chips: |
| + | [* black] 8205A — a Dual N-Channel MOSFET |
| + | [* black] DW01A — a "lifetime" battery protection IC (over-charge, over-discharge, over-current). Funny, the datasheet on this states that it is designed for a single cell, but we do see that here it is connected to two of them. I presume this has implications on a life time in the long run. |
