Vortech battery backup alternate

[gregzz4]

For those of you interested in making your own Vortech battery backup system...

I checked the local costs of a Battery Tender Junior - yipes, $50. Even online it'll still cost close to this with freight.
So I went to Canadian Tire. They had this charger on sale today for $19.99 http://www.canadiantire.ca/AST/brows....jsp?locale=en

And for a rechargeable battery, I went Battery World and picked up a 12v 18Ah sealed lead acid battery, much like this one http://www.mobilityexperts.co.uk/pro...ttery-12v-18ah , for $60.00

I grabbed a pair of EcoTech fused backup connectors from J&L.

I bought a pair of female connectors from RP Electronics in Vancouver.

I should be able to run both props @ 50% for 36 hours off this one battery.
