New Lithium-Ion Batteries
I just came across this new Mastevolt 24V 160Ah batteries. Sounds interesting for a large lightweight battery bank.
MLI 24/160 « Batteries | Mastervolt. The worlds leading brand in maritime, mobile and solar energy solutions.
The Mastervolt Lithium-Ion battery is up to 15% more efficient than a traditional lead-acid battery, allowing: shorter charge times; shorter running hours when charged by generator; more power from a battery of the same dimensions: a lead-acid battery, for instance, has a recommended DOD of 50%; this means that you can only use up to 200Ah from a 400 Ah battery; a Lithium-Ion battery with a DOD of 80% means that those same 400 Ah provide some 320 Ah instead – almost 60% more!
- 70% less weight
- very long lifespan (<2000 charge cycles)
- 90 to 94% charge efficiency (compared to 70 to 83% for lead-acid batteries).
- shorter charging times
Anybody out there using Lithium-Ion batteries?

Do you have any idea of the price?
I've also got to be frank with you, your new thread is depressing. A whole bunch of us were having a fine time over in the "Gel vs. AGM" thread trying to get a few more cycles out of a two hundred year old technology. Hell, Bill and I are hoping to enlist some young ladies into helping us in a truck stop.
Now you show up with the "battery news" equivalent that 30 year old Michelle Pfeiffer has left her husband and she'd like me to give her a call. Geez. Have a heart.
Carl
PS - just in case anyone missed - the above is a joke, Michelle is no longer 30 years old, I assume she's is still happily married and Lithium Ion batteries would cost more than my boat.

I think I read about it in Yachtworld. Forgive me if I get it wrong but I think they said something like:
3 times the price
3 times the life
3 times less weight

Can't find any information as to where to buy them or price. A mystery battery?

Three times the price for three times the life equals the same as gel/agm/lead acid. The only change is less weight. With fewer batteries more ballast is needed. Nice trade but not worth the price.

That's better than Lead acid, but not as good as 3 times the cost, three times the performance at one third the weight (sigh).
I was hoping especially the one third the weight part, having a multihull.

Different Company - maybe same technology??
Mastervolt claims " Weight and space savings of up to 70%." I'm not sure if this includes having less Ah's because you can drain the batteries more.
I suspect the marine market is Cat's and electric/Hybrids.

It all depends on the type of load & duration, when you are looking at different battery types.
Some are better at carrying say constant heavy laods & others are better at carrying spike loads, ie short, infrequent loads.
A lot of this i found disscussed & in video form on youtube. especially in regards to hybrid propulsion.
google a david tether. to find great technical explanations. He, along with the company Lagoon have halted the use of lithium ion batts in the new 50' cat as the performance under trial was not as good as expected or the decca batts.
As i said it depends on the load & use that a battery system is put to.

LIFEPO4
FastCat has some info on this battery. They are using them. I have been looking but get worried with so much variation in price & avail of this product most of which is made in China.(QA?) The EV people have forums but unless you are prepared to go to battery school in a big way I can not see how this is right for our use. I have been told to use 1080 X 1.2AMP cells for my house battery use!! (to replace 12V 400AMP lead acid) Larger size cells are shown (13A-250A range) yep that is one cell sizes!! but I can not get specs. price or delivery.
Some 10AMP cells are around which might work.You will need special Battery Monitoring System as well & likely special charges. At this time every thing that uses this type of battery has a very short life & is the "through away" market ie cell phones ipod laptops etc. Very little avail for the retrofit application. Light weight starting battery or electric trolling battery might have some application. It is all very new with most only starting production in 2006. Maybe in the next 3-5yrs it might be viable with electric cars going into mass production.
For now gel/agm or flooded lead acid if checking/servicing is not a problem. Warning do not get involved with lipo type (unsafe) as opposed to LIFEPO4 which is safe.

Re: New Lithium-Ion Batteries
Mastervolt - 160AH - 55kg - that's 120lbs guys per
I run only 280ah 6v batts for $80 ea....
The math doesn't work.
Can someone help with my logic?

Welcome aboard.
One post since 2006 is a record.
What is the prize Gord?

I think you may be right; and have no idea what the prize might be.
Tony's obviously a man of few words, and ought to be rewarded for sticking with us over these years, even when we never previously elicited a response.
