They all still charge up to like 12.7 or 12.8 and stay there. I have no complaints at all.

D'oh! I am looking to get a 96 volt pack, and I also drive at 35 MPH, but I need a solid 18 miles of range from them, ideally a solid 20 miles. I have hills and such, but my current batteries work well until they past the DoD 50% mark, then they sag like crazy. My usual drive takes me 16.8 miles, and I hit DoD 65% mark and those last few miles are awful saggy, but I keep going.
