I need to make an 2s 1p 18650 battery pack for powering som led lights. It`s important that the end user (my mother) safely can charge this pack and the batteries got proper balance and safety regards to charging.
Can i just use this board where i add an buck converter that gives it ~9V?https://www.aliexpress.com/item/32888974744.html?spm=a2g0o.search0302.0.0.2d604f0fDkmRxz&algo_pvid=null&algo_expid=null&btsid=0bb0623b16250522403295534e2b62&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
Which charge controller do you plan to use?
Wht not buy a ready torchlight charged by, lets say USB?

The protection board is there as a safety backup mechanism , you need to use a proper charger to control the current then voltage , then disconnect at the correct charge point .
A charging module that supports 2 cells is required separately from the that board.
Okay, thanks.
Some ideas witch charger i should choose?
e.g. charging module with TP5100.
Thanks. I will try that
But witch charge module do i choose if i want to charge 3 and 4S battery pack etc. ?
TP5100 is up to 2 cells.
You said at #1 , I provided.
Yes i know.
I just wonder what i should choose when i will charge 3 and 4S batteries with the same setup...
The setup is the same even if there are more cells.
"Balance protection board" at count of your battery cellsAnd "Charge controller" with compatible your power pack total voltage
Please choose the chip brand and models freely.Remember to google it by yourself.
