I use 6 deep cycle batts charged from solar or can use wall charger. I feed a
inverter to power supply so the shack always has 13.8 volts. Deep cycle batts
hold up well and about $ 85.00. My ups for computer has been changed over to
out board deep cycle batt. and will keep me up and running for about 8 hours.
Run time is great and I think its the only way to go. 73

Subject: [TenTec] lithium ion batteries or ups?
the other day I was at a battery and light shop to get a couple of replacement
batteries for one of my ups units.
I noticed they had rechargable lithium batteries presumable for cars…very
light, small but pricey and had comparable ratings to full sized lead acid
batteries…
Wonder if anyone has used these in a ups(uninterruptible power supply) before?
My station 3kw ups uses a 48 vdc, 76 amp hr vdc battery pack that will be due
for replacement one of these days.
