Re: [Electric Boats] Re: promise of cheap Li batteries

the 40 amp hour carries a shipping tag of $7 plus 43 for battery total 50

That seems to be the going rate

... How beautiful it is to do nothing, then rest afterwards

Bob,

Here's a company selling these batteries at cheap prices:　

www.alliancerenewableenergy.com/

Hope that can help you.

I'm from China but that company is an American company, so please do not consider this as an advertisment.

Thanks.

Jerry

Jerry,

What your quoting works out to $0.31 per watt and my last price was $0.39 per watt. Makes a nice difference on a 50kw/hr bank. $15,500.00 vs $19,500.00. Can you link me to the site of $0.31 per watt batteries?

Thanks,

Bob

there're already some cheap lithium batteries from ThunderSky, CALB, HiPower and other Chinese factories. The price is close to $1/AH. I do not think the price will have any big drop in 1-2 years. The advancement of material is not so rapid as technology of IT industry.

Best regards,

Jerry

They exist low rate lipo up 10-20C is cheap - the problem is the chargers they dont go to high enough voltages and the p[acks have to be made from multiples in parallel and the balancing is difficult as for long life every cell needs to be balanced - but it can be done

That would be a game changer if it actually does pan out! I hope they come out soon! Of course I just bought lead-acid batteries for mine! Sea trials soon!
