$begingroup$ @HoussemOuni I think lead-acid batteries are less commonly used with BMSes because the batteries are more robust. E.g. slight overcharge is no problem (it is converted to heat) and the battery doesn''t explode. Also why they don''t come with balance ports - you just trickle-charge for a while and then you know all the cells are full.
