Re: Making a small ups last longer

Thanks Rich

You seem to know a bit about this stuff.

Its getting more and more complicated, All I'm after is a way to keep my radios on at each location (13) for a few hours not minutes.

I was going to go the sla and charger but you talked me out of that one

Can you explain what your doing exactly? Do you mean during a power outage? A large UPS can stay up for hours if not days if properly selected for the load it will be powering.

You need to switch to an "all DC system". You need to get the inverter out of the loop to remove the conversion inefficiencies that are squandering your battery power.

Sounds complicated....but it really isn't. Search here for more information. There have been some long discussions regarding this very subject.

This is what you are looking for.

If thats too much, look into building your own UPS using charge controllers and what not
