I know they make bigger lithium batteries, but an ETX680 battery at 4 pounds and over 12AH is all you need in a KR sized plane.

There's a time and place for that. And if there's no other option, then that's the one to choose. But you are assuming a "problem." I'm presuming to avoid any problem. I don't like problems, especially in such a time and place as this hypothetical ramp in the middle of Wyoming in winter. I'm taking measures, with my battery installation, to make sure as best I can that there will be nothing to interfere with me using lots of electrics to land, taxi to the fuel dowser, fill up, get back in the plane, start the engine and continue my journey. In such a circumstance, if the battery is dead because it's overdrawn, then I have a problem. I don't want that. Anything I can do to help prevent such a problem is something I feel obligated to do. Now, I've admitted my ignorance of lithium battery technology, at least to Larry. I'm admitting that it's possible there is a lithium battery that will match the specs of this M44 battery, same Ah, same reserve capacity, perhaps less weight but weight isn't important to me - I'm just wondering if a battery of this size (garden tractor size) exists in the lithium world that would do as well as this AGM I've got and am so excited (some would say overly) to find. I guessing the military has some specialized lithium batteries with amazing specs and they may very well have something that's equal or even better than this M44 I've now got. I will be keeping an eye out as time goes by but meanwhile, if Brian or anyone knowledgable about sophisticated lithium batteries would like to point me in a particular direction I would appreciate it. For future reference, I'd like to know what is going on in the lithium world of high performance batteries. Dj said, > "There is simply no need to have TWO heavy "substantial" batteries in the airplane." That's probably true. It can't hurt though. It's probably highly unnecessary unless you're stationed in Antarctica or flying in the far north. . ____________________________________________________________ A Balance Transfer Card With An Outrageously Long Intro Rate And No Balance Transfer Fees That Can Save You Thousands http://thirdpartyoffers.juno.com/TGL3141/56202dafe8ceb2daf66d6st02vuc _______________________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
