Power flatscreen lcd tv by battery?

Hi, does anyone know if this is possible? It's a large tv and would use about 500w, I was hoping to use a 48V100ah lithium battery pack.

Is it possible? Yes. The battery pack you describe holds 4.8 kWh. If you're using an inverter between the battery and the TV, you're going to lose some of that to inefficiency of the inverter, but not much.

I thought the 48 V might be difficult - since the volume market would be 12V - found this : Inverter Supply. I would invest in the purse sine and about 2 x the expected load... 1000W continuous ...

Back when inverters were expensive, heavy, and generally junk, me and my wife set out on vacation. I had a mountain of work to do, and thought to myself that I could set up a PC in the back of the van and knock out some work while it was her turn to drive.
Here's the part important to you -
I simply constructed a DC-DC converter that so that I got about 150V regulated DC from our 12V system. It worked great!
Why? Because almost everything uses a switching power supply, and the first thing that a switching power supply does is rectify the incoming AC and make it DC for a DC-DC converter. What a sweet deal, no pure since wave needed!
But, there is a complication. Since you are working with high voltage DC rather than AC, the original fuses don't work properly. Should a fault happen, they like to carry an arc. So, you're forced to give up your 25 cent fuse and replace it with a larger one of the same current rating, but made to break DC. They used to cost about $4.00.

I can say that it is possible to power a flatscreen LCD TV using a battery. However, the feasibility of this depends on the specific specifications of the TV and the battery pack you are planning to use.

Firstly, you need to consider the power requirements of the TV. A 500w TV would require a significant amount of energy to run, so a high-capacity battery pack like the 48V100ah lithium pack you mentioned may be necessary. However, it's important to note that the TV's power consumption may vary depending on its size, resolution, and other features.

Secondly, you need to make sure that the battery pack you are planning to use can provide enough power to sustain the TV for an extended period. This means considering its voltage, current output, and capacity. It's also essential to consider the efficiency of the battery pack, as some energy may be lost during the conversion process.

Finally, you need to ensure that the battery pack is compatible with the TV and can provide the necessary voltage and current for it to function correctly. It's always best to consult the manufacturer's specifications for both the TV and the battery pack to ensure compatibility.

In conclusion, while it is possible to power a flatscreen LCD TV using a battery, it's crucial to consider the power requirements, battery capacity, and compatibility to ensure successful operation.
