however, you will only get 300 cycles before the battery performance degrades to unacceptable levels.

If you wanted to use this deep cycle battery for 5 years (300X5, 1500 cycles), you would only be able to discharge 20%, meaning you would need 5 of them.

So given that you can buy a $169/1200Wh battery right now, and get 300 cycles Or you can consider it a $845 (5 X $169) / 1200Wh given the above explanation regarding cycles.

So for $900 you can get a 100 AH 12v lithium battery, which gives you near 1200Wh, $900/1200Wh to give further understanding about the title of the article. The lithium battery should give you the same amount of cycles as the 5 deep cycles. However they are relatively new in this size and unverified, they will probably perform at this level.

Interesting enough I have been disabling my wifi at home at night because I was challenged to see if I felt a better deeper sleep. I did, but I have not ruled out placebo effect. I want to randomize this somehow and record which days I think it is off (depending on my sleep) vs days it is on, to rule this out. I am horrified that EMF could be affecting me like this if it is true. I live in an area without other wifi, 3g, or 4g. I do not own a frequency counter, but that would help me eliminate other interference for better test results.

The frozen chicken breasts are cooked in toaster oven for 45-75 minutes at 400f in a cast iron flat plate skillet. I usually start the microwave when this is done, because again I am very lazy and need to run another 20 amp circuit to that spot of the kitchen.

I cut up the cooked chicken and put it in the bowl when it is finished. I have it timed so everything is perfectly cooked. Probably the most offensive and lazy way of cooking this dish, quick and about $2.25 total including frozen chicken, frozen vegetables, paste, coconut oil, and milk. You could add $.13 for about 1kw for electricity to be fair.

Turns out I can eat an amazing very low carb meal for about $2 a day and 2-3 minutes of meal prep. It's currently my "meal for life".

If there is a Japanese pre-mixed curry for sale, let me know!

Thanks

I was trying to figure out how to design a system that, given 4 hours of full sunlight at the maximum output of the solar charger (300w) or 4 * 300 w = 1200w total daily charging of my deep cycles. If the system is 100% efficient (it isn't), this gives me 50w a hour over a 24 hour period. 1200w / 24 hr = 50w. But my solar panels exceed the ability of the charge controller. How can I use that to my advantage? I have a well and a holding tank. I was trying to figure out a circuit, perhaps an Arduino program/circuit, with voltage/amp sensors and relays to do this: If there is enough sun, charge the battery. If the batteries are full, turn on the well pump into the holding tank (there's a pressure switch to turn it off when the tank is full). And put the holding tank up on the hill -- which should give me 25-30psi (up 45-50ft). Then I was trying to figure out how to optimize my well pump, or use a DC motor. I might look into salvaging a 2hp DC motor from a treadmill and retrofit it onto a pump housing. Anyway I am trying to optimize for extreme budget. 50w an hour isn't a lot, but it is enough to run a few light bulbs and my tiny refrigerator. I might be able to run a RPi and charge some 18650 batteries for flashlights.

I also get gmail from another account, and he gets mine.

At least it is not as bad as Skype. Woke up one day a week ago, hit Upgrade, and now Skype doesn't work -- whatsoever. Nothing I can do.

Essentially if I didn't have experience as a level 3 support engineer, I'd be out of business.

Yet, the same exact thing just happened world wide in Chrome 69.
