Don't just tighten suspect connections, ensure clean bare metal, if you see corrosion, spray with Fluid Film, Lanocote, or Boeshield, tighten well then try to seal, maybe with heat shrink?

As stated check for voltage drop from one end to the other, hopefully your wire gauge is plenty heavy.

If everything else checks out, temporarily substitute a known good newish batt for your existing bank see if that changes anything.
