Let me try to do a comparison, ok ...
210 x 48 V = 10.080 == 10 kW nominal. Yes.
I am sure/believe completely Your bank has the 273 kg mass You said, yes.
273 kg / 10 kW => 27 kWh / kg, about 12x less than a top-end tsla mobility lion battery in 2017.
Soon:
380 Wh /kg
You had the reciprocal.
10 kWh ==> 380 Wh/kg
10 kWh / 380 Wh/kg => 26 kg
And;
At 1 kg, 380 Wh/kg, => 0.38 kWh
=> 3.8 kWh / 10 kg
=> 38 kWh / 100 kg
So the 26 kg is more/less correct for 10 kWh.
I personally made no innovations as such in these things, facts, mass, costs re: lion stuff and mobilitity.
I claim zero credit.
I simply use/condense/synthesize stuff from others, in this case, as an analyst with 10k+ hours in multiple languages/countries/markets.
And as an industrialist of sorts in IT, with 25+ years of lots of innocation/profits in IT related stuff.

So a lot of my ideas and basic spark on BEVs came from Tony Seba, Elon Musk, others, I just follow this stuff a lot, to a high information density.
A lot of times, money is made by the guys who see things, as well as the guys who invent things.
My major problem is that so far, I see no way to make money (for me) on BEVs or PV.
Any ideas are welcome.

So as you see, Real Soon Now, a similar system lio/anything else will likely be vastly better.
Per your/my numbers.
Anything technical that can be produced, less major physical hazards, will almost immediately occupy all commercial niches.
Lion/boats is one of them.

Note Tsla might pay 112$ / yE 2017.
Probably sell for 140$ or so, 2018.
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 kWhWeight 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+
Current Prop: 2-blade fixed 16X10X1
