Hello
I have a Lithium ion battery pack that uses a small protection board
that protects the battery pack from short circuits and under voltage.
I am using 2 lithium ion cells in series for a nominal 7.4 volt output.
The wierd thing is the protection board has to be first initialized
by applying a voltage across the P-,P+ outputs. It will only turn on by doing that.
Here is a link to the board:
Link to board
The board has 3 inputs that are used to connect the battery.
Negative pad, positive pad and pad that connects between the cells.
It also has 2 outputs P-, P+ that connects to my dc-dc buck converter.
I never heard of having to do that and makes the board useless IMO.
Wondering if this is normal and all protection boards have to be
"initialized" before using.
Thanks for your help
