Lithium Ion Camper Batteries - Bleeding Edge or Inevitable? Smart Battery vs Elite

Hey All,

Onto the final layout stages on my camper. We've been debating power sources for a while now. While the lead acid is a proven technology, the drawbacks are considerable, atleast to my mind. And given that some of the big manufacturers, Blissmobil and Unicat, offer or insist on LiON, it leaves me wondering if this is just a matter of time thing, for the tech to mature to a point that all will use it. And in our case, if this is the right time? Despite the cost, are they there yet, and reliable enough if you are willing to shell out the coin..

I'm familiar with most of the big arguments on either side, replace-ability in remote locales, reliability, extent of discharge, lifecycle, complexity, price etc etc.

Anyone have any comments on the offerings from smart battery and elite power solutions?

They are pricey, but about 30% the weight, allow safe discharge down to 80% at 3000-5000 cycles. I like that the smart battery has its computer control integrated into the casing. I have a friend with the elite power offering, and theyve broken their coupling cable between the battery and the charge controller a few times.

If the cost isn't prohibitive, is this the right call these days? Any other preferred solutions?

I don't see a problem with it, other than I seem to remember reading somewhere that lithium ion batteries have a limited lifespan whether you use them or not - i.e., go bad even if all the do is sit around fully charged and never get used. I don't know if that's true or not.

Looking at the first link I see a couple of questions I'd want cleared up. In one place it says max charge current 100a, but in the tech specs table near the bottom, it says 1-10a.
Also in that tech specs table it says max discharge current 10a. However in the datasheet just below the table, it says 100a and shows a discharge curve for 100a, so I suspect the table has typos.

Also, how do they behave when used in parallel or serial rigging?



The second link seems overly complex to me for overlanding, but hey, anything can be made to work if one is dedicated enough.

I also like that the battery in the first link can be used with any ol' 12v charging system and is designed to be a simple direct replacement for a regular automotove/marine battery.

It's just a matter of time. Lighter weight, smaller package, can discharge 80% instead of 50%, etc.
