Hello all,
I am building a 5 volt battery pack and using two li-ion batts in series along with a dc-dc converter. I purchased a 2s battery management board,
here is the link https://www.amazon.com/gp/product/B01KYZ5R2G/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
Even with fully charged batteries there is no output from the board. I have to apply voltage to the P+ output in order for the board to output battery voltage. Is this normal. I have been trying to find a board where it does not need to be activated but reading the comments on these other boards buyers report this problem.
Just wondering if this is normal.
Thank you.
