Was going to tack this on to one of Hannu's threads but figure it might be better in its own..
Just trying to do a sanity check on the basic math, comparing my 48V AGM battery bank with Real Soon Now lithium ion prices/energy densities.
Please point out my error(s). :-)
My AGM bank:
Capacity 10 kWh (210Ah @ 12V X 4 batteries in series)
Weight 600 lbs (273 kg)
Cost $3K USD
Real Soon Lithium:
Capacity 10 kWh
Weight 1 kg/380 Wh X 10,000 Wh == 26.3 kg (Wow, that's a lot less than 273 kg)
Cost ~$1K USD (@ $112/kWh)
I must've lost a decimal point here and there in my calculations.
Ox 1976 C&C 33
LOA: 32.87' / 10.02m
LWL: 26.42' / 8.05m
Displacement: 9800 lbs./ 4445 kgs.
Propulsion System: Electroprop Racer
Batteries: 4 X Northstar 210 FT Blue+
LOA: 32.87' / 10.02m
