DIY Battery Backup (UPS)

[chromakey]

Good Day:

I am looking for some information on making a battery backup for my 28 Gallon Nano Reef Tank. I would like to be able to run the pump and heater. I am located in Victoria, BC and also would like to know if anyone else is interested in sourcing out the parts to do the build.

I would like to know which components that people had success with for building the battery backup.

Thanks,
Michael
