Lithium battery?

Anyone tried one of these or know someone who has?

Seems good from the description although a very expensive alternative to the lead acid batteries.

Maybe a bit easier to have on an internal console shelf being allot lighter ...

Text from the manufacturer is:

The NEW V2 LiFOS 68Ah Lithium Battery (equivalent to a 120Ah leisure lead acid battery) is an advanced battery using the new premium in lithium battery chemistries Ė Lithium Iron Phosphate (LiFePO4) Ė which delivers reliable and safe power in virtually all conditions. Perfect for voltage sensitive and high cycling applications including leisure, commercial and off grid renewable energy installations. Up to 4 LiFOS V2 batteries can be connected in parallel or series to create a power bank of up to 272Ah or 48V.

Iíve just changed the campervan battery to Lithium, I looked at this one during my research but eventually went for the Epsilon superB. What are you wanting to use it for? I donít think itís suitable as a starter battery iirc. Make a nice house battery for the electronics.

Yeah hadnít thought whether I would go for it as either a starter or just for electronics(or at all, it is £660!), donít really know what power characteristics it has - what would make it good / bad as a starter battery?

It may not be able to deliver the current required to start the engine. You also need to check the charging characteristics, lithium needs a different charging profile to Lead Acid, you might have to fit a B2B charger. (Battery to Battery)

Just had another look at this & I donít think itís for your application. Itís quoting ďuptoĒ 1000W which translates to 83A which would start (just) a smaller outboard, but is nowhere near the 300-500ccA of lead acid. As a house/electronics battery itís serious overkill assuming youíre on a ďnormalĒ RIB with the standard plotter/sounder/vhf etc. You wouldnít need a 120Ah battery for that amount of load normally. It would do the job very nicely, but so would a 55Ah quality AGM or Gel battery at a fraction of the cost & a couple of kilos more. Give it a few years for the tech to mature.
