1. The board starts to pass the current only after applying voltage to the load contacts. Use the board solely for protection against overdischarge normally does not work. 2. The reinforced contacts for connecting the battery can only be soldered with the active flux at high temperature. These areas during soldering are separated from the board.
Works just as described, very nice. Charged Li-ion batteries to 4.25v each (8.5v total) before overcharge cutoff.
