I replaced my 20 6v lead acid golf cart batteries with a full Nissan
Leaf pack (48) modules (3 parallel, 16 sets of 3 in series) for a
nominal 128v pack (130 volts fully charged).
The weight was much lighter, and the range was much better (and the
longevity is better as well!)
You definitely do need a good BMS (the Mini-BMS I used works OK as an
alarm circuit, but doesn't balance well enough....).
I recommend the ThunderStruck motors 2500 charger (with EVCC and j1772
inlet if that is important to you) for a 2.5 kW charging solution that
is relatively inexpensive.

I'm using used Leaf modules in my Truck.
Assuming 8.4v per module (fully charged), You could use up to 17 in series.
(might want to drop back 1 or 2 to keep from getting too close to controller
limit)
New modules are 60AH, old used ones like mine are more like 40AH. So assuming
old modules, to get a similar AH capacity, you'd need 3 in parallel.
This would still likely give you more range than the Lead pack, as they would
be lighter, and a somewhat higher voltage.
