nps questions?

[Dtackett]

so my tank (once this one is setup) will only use around 60 watts of power, im looking to get an nps finally because with this small of a tank I cant have any failures. suggestions for an affordable one? I have a bit of a redneck setup now with an extra truck battery and a power inverter but that doesn't do me any good if im not home when the power goes out.

if I did the math right, it should run my tank for 12 hours which means worst case scenario my tank will be without power for about 20 minutes before I get home from work and can switch to battery power and find a way to charge the nps
