currently I use a Raspberry Pi Zero W (connected via Wifi, so Wifi is on) as load.
What confuses me is, that there are so many different values are given for the cut off voltage of LiPo
cells, which all works with the same kind of chemistry.
A company selling LiPo cells is interested in producing cells with a high capacity for lower production costs.
Specifying a lower cut off voltage (as may be advisable) will give more useable capacity (may be for the cost
of a shorter lifetime of the LiPo cell...but that happens the cell is already sold).
I am trying to figure out, what cut off voltage is advisable based on physical reasons -- not based on marketing reasons.
But takeing the highest mentioned cut off voltage (say 3.3V, wikipedia) blindly is as wrong as taking the lowest value blindly
-- on the other end of the scale.
Please dont get me wrong here: I don't accuse any company for giving wrong technical data here. The premissions are simply
different: I dont want fires
and a long living LiPo cell and the company want to sell as many cells as possible for as less production
costs as possible. This is called capitalism
(And: NO, I am no communist, despite the fact, that I used the word "capitalism"
Without harming the lifetime of my LiPo cell and without the risk of a fire: Can I solely rely on the cut off mechanism of the
DW01-PCB in the cell ... or is it kind of "last resort if anything else fails" ?
