<p>im running the 30 amp unit, after a start max current runs to "fill up" my earthx battery. running dual dynons, lights, radios, xponder, comm and gps. plus always on fuel pump and current for electronic ignition</p>

<p>Will the 12 amp alternator adequately recharge your battery(s) and power everything. <br/><br/>We choose to leave our WigWag, Nav, and Strobes on in flight for maximum visibility, but then we also have a different engine, 40 amp alternator, and two batteries.</p>

<p>I have the B & C 12 amp on my O-200. I only fly day VFR but do have lights if I come home at twilight. I was a bit concerned that I wouldn't have enough power but weight was really important to me (and I also found a good deal on Ebay). My plane is pretty light electrically equipped with a Dynon D-180, Aera 500 GPS, FlightLine 760 Com, Narco transponder, Uavionx Tail Beacon, LED landing, taxi and nav lights.

<p>I have the B & C 12 amp on my O-200. I only fly day VFR but do have lights if I come home at twilight. I was a bit concerned that I wouldn't have enough power but weight was really important to me (and I also found a good deal on Ebay). My plane is pretty light electrically equipped with a Dynon D-180, Aera 500 GPS, FlightLine 760 Com, Narco transponder, Uavionx Tail Beacon, LED landing, taxi and nav lights. I do have the original incandescent strobes that came with the kit so I could save about 3 amp with LED's. So with that setup and flying mostly daytime I really have no issues with the alternator not keeping up. At idle, of course, it doesn't generate enough to keep up with the load but that is just during taxi, I usually see about 2-3 amp discharge during taxi. After takeoff the battery is topped up to full voltage after about 15 minutes typically. Also, the important stuff has onboard battery backup if something does go south.</p>

<p>I am sure I don't have much margin so you gotta keep an eye on it but for my plane it has been just fine.</p>
