DIY Vortech Batt BAck-up and electrical engineers out there?
DIY Vortech Batt BAck-up and electrical engineers out there?
can this be a straight calculation - i.e., the vortech is 30 hours and you're saying 12v 18 amp =~ 36 hours so would that mean that the Jameco option which is 12v 4.5amp is roughly 1/3 of the 36 hour option cited above and therefore the pack they sell would last about 12 hours? If so. that's a DIY battery backup that lasts 1/3 the time and is only half the price (not accounting for the cost of the risk that it won't work as intended) so it really doesn't make sense to make this back-up buying from vortech is a better deal. anyone with a background in electrical engineering want to weigh in?

oops - i know it's been a while, not sure this will be seen but i'll ask anyway...

I know this is an old thread. There seems to be question if this works. There is nothing fancy to the setup. Power goes out control unit uses source of backup. 12v dc is 12v dc 12v dc. Amp hours is the like the size of your gas tank. Higher the number the more charge the battery holds. Vortech uses 18 amp hour battery's. Here is an identical rated battery for a fraction of the cost. http://www.apexbattery.com/genesis-np18-12-battery.html?utm_source=googlepepla&utm_medium=adwords&id=18283950120&gclid=CjwKEAjwpIefBRCuir7wy-f1kCwSJADXBi2a98TIgnRxSAYqyCg0GcwBT7crs8NCJUATjT75QXMh5BoCCR_w_wcB
With the addition of a plug and some light gauge wire you have a battery backup for a fraction of the cost.
