Has anybody seen the new domestic batteries Mr Musk's Tesla is bringing out? I know they're for fixed installs, voltages are all wrong and they are in no way intended to be used in Marine applications.... but what if someone could 'marinise' them, so to speak? Could be quite interesting in a (biggish) marine application.

3500USD (2300GBP ish) for 10kWh (Equivalent to just over 400Ah at 24V). I'm pretty sure when it comes to cost you could be an many times that if you were to go to some of the big players in marine specific, industrial Li batteries.

Just a thought.
 
Wow that is a big step change in pricing. Mastervolt is £4k for 5kwh (handily 24v of course). What we need is a reconfiguration of that Tesla battery to 24v and I'll have a couple! Surely you can do that in your garage Anna? Just swap around a few parallels and series between the cells, right?! :encouragement:

I've been in a few Tesla S's recently. Completely awesome machine. If I needed a car that's what I'd buy
 
Me too. Schipol Airport are doing a trial with an all Tesla fleet of taxis at the moment. Great machine, super quick and reportedly a 400km range from taxi driver's mouth recently. I hear they have had quality issues though with bits falling off.
 
I'm always surprised to see the Tesla charging station that they installed in the Sainsburys car park just down the road from me. It's rare that you don't see two parked up and on charge - and it's always a different pair, not just the same two nicking all of Sainsburys' leccy! Clearly they're growing in popularity.
 
Their pretty expensive really, its not just the batteries but the management as well. I am trialling our version of lithium on my boat, which are set to retail around £800 for 100ah @12v. doubt ill have a power issue this season ;)

Boss has a tesla... and its mental. a few 0-60-0's in a row and you go very green.... :D

That's £800 for 1200Wh = £6666 for 10kWh vs Tesla's £2300, hence me thinking it's quite cost effective.

I do a lot of designing LiFePO4 batteries/systems, and based on the cost we see for the cells (even in 100k off quantities) the Tesla battery does seem very good value. We couldn't even get close, even if it was cells and no management/case/anything else!

They are big though as has been pointed out. About 3 times the volume compared with a setup of Mastervolt's big LiFePO4 blocks.
 
Anna, what do you think of the Tesla technology? Cleverer people than me say they are not impressive, just low cost? Even so, the cost of the batteries and power management is about $50,000, in a car priced at $75,000 in the States. The sums don't add up as a business yet, and this is the only car factory I have visited where you get valet parking.

Until you sell your carbon credits to a desperate manufacturer of traditional internal combustion engined cars.....

Ofcourse yes we would not be able to be competitive on that basis, but for smaller craft (like mine and im sure a good deal more) 100ah is more than adequate, especially given the fast recharge rate and full 100ah capacity. you do get the whole package though, one battery that looks like a battery, connects like a normal battery, BMS is all internal ect... but we are only trialling them, i doubt they would make it to market. as a friend pointed out, you can buy a lot of lead batteries for the cost of one of these!!

Certainly interested in the tesla ones, this can only lead to cheaper better batteries if being made on such an economic scale, certainly give the Chinese a good run for their money....

I'm not aware of this happening yet H, but no reason to believe it couldn't. Porkers now benefit from Up and Polo credits in the U.S., just JLR as volume manufacturer with no small car affiliates.

Thought they were a subsidiary of Tata.
