fly boy3 Posted June 3, 2011 Share Posted June 3, 2011 Hi all, I am trying to reduce the weight I lug around in my flight box. Would a 12v 7Ah battery turn my electric starter when using it to start up to a 62 f/stroke motor. Cheers Quote Link to comment Share on other sites More sharing options...
Reno Racer Posted June 3, 2011 Share Posted June 3, 2011 I use the same battery to turn over my Magnum 52 XLS 2 stroke and my ASP 61 Four Stroke without any problems, and that includes a good mornings flying (6 hrs). Hope that helps. Quote Link to comment Share on other sites More sharing options...

fly boy3 Posted June 4, 2011 Author Share Posted June 4, 2011 Cheers both,I can now go and buy one without the the worry that it could be a bit small. Thanks. FB3 Quote Link to comment Share on other sites More sharing options...
Ed Darter Posted June 6, 2011 Share Posted June 6, 2011 In a strange twist of coincidence I have flattened my flightbox battery and now need a replacement. Not having a lot of luck with batteries at th mo :-/ Anyway - a couple of members at my club have suggested using a 3 cell LiPo.... certainly lighter and although a cheap one wouldn't be 7Ah they are easy enough to charge these days. You would have to be going some to actually use 7A for an hour. Worth a thought. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted June 6, 2011 Author Share Posted June 6, 2011 Hi Ed,thanks for the idea. It had crossed my mind too, but not being part of the leccy brigade thought no more of it. The7Ah idea came about as this was the smallest I could find locally. Cheers. p.s. also wondered what amperage an electric starter would pull in use ?Edited By fly boy3 on 06/06/2011 14:22:52 Quote Link to comment Share on other sites More sharing options...
Ed Darter Posted June 6, 2011 Share Posted June 6, 2011 not sure to be honest, the guys who suggested the LiPo idea to me have also modified their starters so that there is a big(ish) 3 cell LiPo velcro'd to the side of the starter, works a treat and means no trailing cables. Align sell a starter designed specifically like this. Also means the LiPo in the flight box can be quite small as it only needs to power the fuel pump, and a glow clip if you don't already use a portable glow clip.
