Always nice to see new things. Does look interesting for installs where weight and space is not a big concern.
3000 cycles to 70% retained capacity? Not 70% DoD so in effect an 80ah battery is going to be about 24ah (3x8).
Hmm.
I suspect on a large barge the best solution would be a very small efficient diesel generator which you run all evening for domestic requirements and a bit of charging to cover the next day until evening
And a small battery bank. And solar obviously. Or possibly a sterling engine unit of some sort but availability is an issue with those.

Interesting I can't see a price though, it usually costs mega to be at the bleeding edge of technology.

I think they are claiming that you can discharge to 100%DoD and after 3000 cycles your battery will still have 70% of it’s original capacity. If true, that is impressive. |

Interesting I can't see a price though, it usually costs mega to be at the bleeding edge of technology. Quick Google suggests about USD1000 for a 48v 48ah module. About 2.5kwh. Is there a uk distributor? I guess the equivalent in SLA would be 4x50ah 12v batteries so maybe about £150-200? So its about 4 times the price. And a 200ah 12v lithium (LiFePo4) seems to be around £1200 or so. So it is cheaper than Lithium it appears. Or probably a similar price once delivery etc is factored in. |

Bimble Solar are doing them 24v 2KWh for £1,410 inc vat |

Deleted as was being thick ! They are rared in kWh not Ah.. voltage would therefore make no difference.

They say they are safe batteries I wonder if that means you could have one in the cabin rather than in engine area. On smaller boats there is more chance of a bit of spare room inside than in cramped engine compartments. Does look quite intriguing. I wonder what the required charging regime would be ie amps in and voltages etc. Are there actually any suitable chargers available ? Will it work on an ordinary alternator etc. More reading  |

They do seem to state that they are meant for staionary installations. That's probably just because of the weight though.

Always good to do some research into,the company behind a technology.

Yes and its wikipedia so could be a load of old molluscs .
Maybe it is such a great technology it was seen as a threat and someone attempted to torpedo it.
