How cool is that! Digikey has them for ~$8. Just seems like it would be fun to play with. (I just might have to move to somewhere there is a lot of lightning - I live in southern California on the coast and we might get o 1 or 2 thunder storms per year) that would make it difficult to test such a device. _____ From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Robert L.

I couldn't find anything on the websites for Aerovoltz or Full Spectrum (the two brands sold by Aircraft Spruce) and was puzzled by the claim of 20 AH for a 2.5 pound 12 volt battery. It turns out that "lead equivalent" amp-hour capacity is actually three times the actual cell capacity. http://www.batterystuff.com/kb/frequently-asked-questions/powersports-batteries-faq/lithium-iron-faq.html This would explain why these new wonder batteries, although great in some respects, don't last quite as long as we'd expect them to! We know that you don't discharge a lead-acid cell more than about 1/3 or it will suffer loss of capacity. Sometimes, as in the case of losing an alternator at night or IFR, we're happy to kill a battery if it gives us power for long enough to land safely. Some LiPo and LiFe batteries can be discharged to 80-90% without damage, but this doesn't help us if we are expecting 20 AH and the battery is actually made of 6 AH cells. If you want to know how long they will run your radios while you're up in the air, you need to know the actual cell capacity and discharge curve to figure out how many minutes you have before the voltage drops to the point that's unusable by your equipment. -- David Josephson ________________________________ Message 7 _____________________________________ Time: 01:58:23 PM PST US From: "Robert L.

The next item is in process; hardware is done. Software is moving along for a battery capacity meter that will be useable either on the bench or in-situ on an aircraft.

Dear Listers, Good news. I was able to roll back to Skyview 5.0.0 using a special roll-back file supplied Mike Schofield at Dynon and carefully followed a procedure he outlined to accomplish the task at hand. I am again getting an EMS data feed from the Skyview to the VP-200. I haven't flown or started the engine yet, but I flipped on the Boost pump and saw fuel pressure so that's a good sign. Hopefully Vertical Power will have an update for the VP-200 soon... I had a long phone conversation with Mike Schofield, Marketing Manager at Dynon about the trials and tribulations of late. He was sympathetic to the plight of those of us utilizing their EMS protocol, but didn't seem like they were planning on really doing anything procedurally any different in the future with respect to not compromising the data integrity of the data format for devices such as the VP-200 in the field. I indicated that as a developer of products that might potentially use those protocols, I would be uncomfortable choosing to use those data feeds because of the lack of commitment to their stability and continuity by Dynon. I guess I got my point across. He went on to say that they hadn't intended for the protocol to be used by autonomous devices like the VP-200, but rather foresaw it simply being used as raw data that would be captured and used for post-analysis like with a spreadsheet. I countered that even in those applications, some consistency of format is expected and consumers of the data might very will write scripts and/or code to interpret the data and would be put off by constant format changes. Anyway, Dynon is a small company and they've got a lot on their plate and a lot of customers asking for a lot of different things. I think they get it, but it sometimes takes events like this to show them exactly why these things are important. - Matt Dralle RV-8 #82880 N998RV "Ruby Vixen" http://www.mattsrv8.com - Matt's Complete RV-8 Construction Log http://www.mattsrv8.com/Mishap - Landing Mishap Rebuild Log http://www.youtube.com/MattsRV8 - Matt's RV-8 HDTV YouTube Channel Status: 172+ Hours TTSN - Rebuilding Fuselage After Landing Mishap...
