Now I've put the extra main MOSFET on, should I be okay with a 15A or 20A charger? I built it solidly with nice thick gauge wire everywhere. Are there any issues I should be aware of before I try it with anything more powerful (apart, of course, from making sure the EOC is stable and works okay now)?

Could you elaborate on this? Do they measure a lower voltage? and by how much ? and does this effect come in after standing for a while or are they cutting off early ?
None of mine are exactly the same particularly after an hour or so. and are you leaving something like the cell log across them ? It does consume power
