Hello R2R, I am sure battery back up have been built in the past and this is not something new but I like doing projects myself and this is my version of making DIY battery back up for my 8 Vortech pumps, I have 6 MP60, 1 Vectra L1 and 2 MP10 pumps that are running on my tank. I have stand by generator which kicks in after power outage but after power comes back on I have sync my vortech pumps with WXM module, If I don't do that it comes up missing for all the pumps on Apex Fusion, so I decided to build battery back up which keeps my pumps running uninterrupted and I don't have to sync my pumps with apex again and again, this is simple diy project and I tried my best to keep it simple, since I have garage and I have access to car batteries at wholesale price, I decided use 24 group 12V car battery, below is the list of the parts that I have used for this project.
So everything listed below is pretty cheap and easily available, so I started with tinning all the female 3.5 mm x 1.35 mm connectors and solder red and green wires to the connectors, I have 8 pumps so I had 8 female connectors soldered, I glued 2 jumper connectors on top of the battery and 1 is connected to positive side and 2nd is connected to negative side of the battery an then I jumped each connected with wires so that I can use 1 side for positive and other jumper connector for negative side, this made this build simpler. I drilled holes on the cover of the battery case and installed female connectors with nut that came with connectors and connected all green wires to negative side of the jumper connector and red wires to positive side of the jumper connector and then ran wires from positive and negative terminals to feed power and ground to both jumper connectors, lastly I installed female connector 5.5 mm x 2.1 mm to connect trickle charger to charger the battery. Below are the pictures I took while I was building this, it took me 1 hour to put everything together, I can run 10 pumps with this battery and charger will keep this battery charged 100%, I have ordered digital battery status screen that will show me the status of the battery at all times, I will post pictures when I get the digital meter, here are the pictures of the build.
