Edison Batteries
Hi Folks, Has anyone considered using Edison Batteries? (Nickle Iron). http://ironedison.com/ and http://www.zappworks.com/index.htm A FAC page here: http://ironedison.com/technical-...

Don,
I scratched my head a bit more regarding your capacity vs weight conclusion above.
Note that those Edison Batteries can be discharged to zero/near-zero with no damage. That means that one can use almost the full 112.5 amp hours out of a 12 volt, 140 lb., RV version of them (10 of them in series @ 14 lbs. each). As a comparison, my two 12V, 115 amp hour each, AGM RV batteries (for a total of 230 amp hours) weight together about 144 lbs. (72 lbs. each) and I should only use out of them no more than 115 amp hours (one half of their theoretical total capacity) during any single usage cycle.
So, if one can afford them ... those Edison batteries might be a pretty good RV battery bank to buy once in one's RV lifetime and then keep transferring them into each different RV one might own.
The only other concern might be the room that ten(10) of them might take up for each ~112.5 amp hour battery one would want in their rig. I haven't worked out a volume size versus amp hour apples-to-apples analysis to compare against fitting in lead-acid or lithium batteries. HOWEVER if one can find room for them, it looks like the Edisons might last way longer than any equivalent lead-acid or lithium bank of batteries.
Perhaps going back in time can sometimes lead to superior technology. And to think I used to consider air capacitors as the "perfect battery" (ignoring the required size of an equivalent capacitor battery bank). Way to go Edison!!!
