Once I finish my electric motorcycle I'm really temped to go with lithium batteries, so I sent them an Email about their packs, 8Kwh seems like a good size for a motorcycle so that is what I asked about and this is what I got back:
"Our standard pack is 24V 80AH. You can use two packs in series and two strings in
parallel. Two BMS to monitor two strings. The normal discharge rate is 160A-320A in this
configuration. each 24V80AH pack is $800, BMS is $170, 15A charger is $150. The total for
this 80KWH pack would be 4 x 800 + 2 x 170 + 150 + $250SH = $3940"
