DC to DC UPS for Synology NAS

[Neville Bailey]

I have a Synology DS220+ NAS (12V 5A) which I have connected to a regular inline UPS.

The UPS is connected to the NAS with a USB cable which controls the automatic orderly shutdown of the NAS in the event of a power outage, and thereafter the shutdown of the UPS itself. When the mains power is restored, the UPS wakes up which in turn wakes up the NAS.

This setup works flawlessly.

However, I would now like to change the setup so that the NAS can stay powered up continuously throughout a load shedding session, so I have started researching DC to DC UPS units that use Lithium Ion batteries.

I am yet to find a DC to DC UPS that will have sufficient power to keep my NAS going for at least 2 hours.

Can anyone recommend a solution for me?

There are lots of options here. You can buy one of the blue nova/mustek lithium batteries and chargers and a dc buck convertor to output the 12v. But it seems like upgrading the UPS battery capacity will be a better option you get drop in replacements ib some cases. What UPS is it?

What UPS is it?

It’s a Mecer ME-650-VU unit.

I've got a similar setup - I actually feel a little relieved knowing it will shut down gracefully. I would look at better batteries for the UPS.
