Lithium spec questions

[golfboy64]

Ok Ready to convert to lithium on 2014 RXV Research suggest a single 48v pack is best, multiple 48 v packs in parrallel 2nd and 12volt packs in series last.

you can find 100A-H battery, charger bundles from say $1400 to upwards of $3K. Some have up to 12yr warrenty but if you dig in alot of the term is protated and you must ship your batteries back to supplier.

Questions:

IS the BMS rating the same as its continious discharge current rating? (seems like getting and underated BMS is source of prolbems)

An estimate of peak current draw for my cart? and an estimate at full speed? My cart has 21in dia wheels runs about 22 mph.

Some blogs suggest cheap packs may use grade B cells but what vendor would advertize that? Or do you basically get what you pay for?
