Nuckolls, III) ________________________________ Message 1 _____________________________________ Time: 08:29:13 AM PST US From: "Robert L. Nuckolls, III" Subject: AeroElectric-List: Next Gen 9005 While taking breaks from less entertaining tasks, I've massaged the original AEC9005 LV warn circuit into a more modern equivalent. Like the original 9005, it features a robust pull-down transistor . . . with a little shuffling of parts, the module can be converted to a battery low voltage disconnect for preventing fatal over-discharge of a LiFePO4 battery with no BMS. Drawing attached. This is an architectural cartoon, parts call outs are non-sensical. Next step is to select appropriate values. This board will probably assemble on less than 1 square inch of real estate and mount directly to the solder cups of a d-sub connector. i.e. very low packaging labor and expense. Total bill of materials on the order of $5. ECB's should be really cheap too. Bob . . . Un impeachable logic: George Carlin asked, "If black boxes survive crashes, why don't they make the whole airplane out of that stuff?" ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
