The other thing I would observe is that if you put a regulated dc power supply between the battery and the soekris you can put up with a multitude of sins that might otherwise be fairly messy depending on the other components used. obviously pulling your gel cells down to the point where they are flat is not such a great idea from a lifespan perspective but a 12volt 7ah battery should run a 5501 for about 10 hours at a minimum unless you have lots of perhiperals. > all electronics corp is probably a good place to start... in fact: > > http://www.allelectronics.com/cgi-bin/item/BC-80/search/2_AMP_%22#34;SMART%22#34;_BATTERY_CHARGER___MAINTAINER_.html > > looks promising > >> Bill >> > > _______________________________________________ > Soekris-tech mailing list > [email protected] > http://lists.soekris.com/mailman/listinfo/soekris-tech > _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
