Anybody using them? From Boating Leisure Services' website: The high capacity domestic battery bank is made up of four 160Ah Lithuim Batteries wired to provide 320Ah at 24 volts which allows all of the onboard facilites to be used for a couple of days without recharging. The discharge profile of Lithium batteries means that virtually all of the power is useable (by comparison, conventional batteries require charging at about 50% capacity). Additionally, the recovery rate of lithium batteries is much faster than conventional batteries; the battery bank can be recharged from flat to fully charged by running the engine for a few hours. www.boatingleisureservices.com/For a liveaboard could they remove the need for a generator? They're £1500 each Thoughts

If you have a shore line or a generator which can charge any battery back up within the required time frame, then all well and good. If not, then you need to start considering your useage. We run happily on 2 x 6v lead acid domestic batteries (in series). That is because we don't have a washing machine and we have a gas fridge. The beauty of the arrangement is that when we cruise for 3 hours, they get pretty much fully charged up and stay within the healthy 50% to 100% limits. The other advantage is that when the time comes to replacing them we only need to buy two lead acid 6v batteries. Lithium batteries still have a limited number of life cycles so I'm not convinced they are an economic option. They are great for situations where weight is an issue though. On a narrow boat this is not really a problem!

We have 2 'leisure batteries' and a starter battery. All we need electrickery for is the water pump & shower Whale Gulper, and for the lights, two of which are LED and these are the only ones we have on for long periods, as the other fluorescent ones get hot (which must take a hell of a lot out of the batteries). I also bought 2 Camping Gaz lanterns when we bought the boat 2.5 years ago, haven't used them yet but hoping to on our next trip when they will hiss and glow romantically. Candlelight is nice too but I would never have naked flames near the pointy end near the gas bottles, just in case. It's nice to put little candle lanterns on the roof at night, and one on the tiller stick.

I've today replaced a bank of batts. I did look at lithium, but was not happy that they deteriorate quite quickly, life wise. Even with providing my usage and charging program, no one could give me a life expectancy.
I ended up buying 6volt crowns.

Like you we only need a few hours to kick 3 x 110a batteries back in the guts, in fact, these days I seldom switch to the start battery (number 1 position on the isolator) I can't see the point if there is enough juice to start from the domestics.

Are you sure your domestic batteries are rated for the high current demand of starting your engine Gazza? Many domestic batteries aren't! Having said that (now my catch phrase), if my starter battery packed up, I'd temporally connect it up to my domestic. Wheteher she is up to the job of turning the handle...who knows?

Yes, I'm too tight to buy leisure batteries I use 110ah batteries due to space constraints in the locker. Up till recently I used to have cast offs from our 7.5t iveco, it does loads of short journeys so kills batteries in a short timeframe, being 24v it often would kill one leaving one okish battery. The truck would get a new pair and I'd of 'dispose' of the duff ones

They're £1500 each Thoughts My thoughts are that I can buy a hell of a lot of red diesel for the £3,000 it would cost to put two lithium batteries on my boat.

With the bad publicity Lithium ion batteries have been receiving from the Boeing 787 to the recent Samsung Note7 issues and their cost, it might be prudent to stay with lead acid batteries for awhile longer.

I tend to agree. Lithium batteries and the management they need, both in the terms of safety and longevity are not something that their installation on the average narrow boat could be recommended for.
A standard lead acid battery, even good one costs £75 and with lithiums costing £1500 they would have to last 20 years to be cost effective. The only battery that I know that has that life used in a NB are NiFes where a 12v 400ah bank will cost of the order of £2100. These will put up with the type of life that batteries get on NBs. Lithiums in their present state of development won't.

So you would have to alter your alternators and battery charger.

I have approx 800-900ah of Nifes that came with the boat. They where built by lucas in the 50's supposed to last over 100years. I've looked into rejuvenating them, but as I say it's the voltage they need that is difficult. Just too good to get rid of so another thing just taking up space.

My twizy had lithiums in it 60v i rented it from renault at 45 squids a month if it failed they replaced it [not heard of any failures] now my boat has 1500ah of full tractions 2v cells one bank is 10 years old already and was checked out this year as A OK by IBCS. I fully expect to get 20 years out of my batteries but time will tell
