All of you members … you need to seriously do your homework… I don’t want to hear in the news how experimenters flowing themselves or houses up. The thermostat and control boxes in a hot water heater are AC devices not DC …when you put DC through contacts you create a large arc and run the risk...

People, I hear a lot of talk about how things feel or look good and probably might work . None of this is real or has direction, guessing and looks good isn’t an answer. I have been an engineer for over 40 years and much of the guesses people make in this forum literally scare me to death. Take...

You do understand that they have been putting propane HW heaters in RV’s for over 50 years so I am sure they have the bugs worked out, AND they use them inside homes as well. Propane is better than electric for batch heating, but I use electric as a propane HW heater water preheater run off my...

Yes was that store I just look up reciept

I will look, I think so. 420 ah. I think store was Eshare something.

I have punched 4 batteries as well and all were at 265 to 274 AH .. aliexpress said I need to contact the seller and I told aliexpress I sent 4 messages over the month with no response.. I am glad I only bought 4, I originally only wanted 2 to test but was told they came as a 4 matched set … boy...

Foam and plastics take a set with time, maybe couple days maybe a month, but they will loose their compression guaranteed.

I received my delivery as well .. and first two tested were also really low. #1 272 ah. #2 267ah. as received 0.026 v cell variation . as recived used std practices to equalize cells than .1 charge rate and a 1 hour soak.

If you think about it, big industry has for years been squashing this technology to line their pockets. Now foreign markets who have been doing technology with the thought basis of customer have or have not ( have power or no power) are marketing their product overseas now the big manufacturing...

I dont know about volcanic eruptions but am an electrician engineer for over 30 years and me understand failure modes and effects and reliability indexes and do believe in the saying KEEP IT SIMPLE and AC and DC are not the same. My system is off grid and has been running flawlessly for 3+ years.

btw there is a huge surplus of lithium in China and I the are producing a lot of batteries now at reduced prices, but as with anything in China beware what you buy, they will sell you anything you want to hear.

I looked up the specs and the discharge capacity was only 3500 mah. I asked the company and they said that’s how it discharged . I was going to buy 4 to test but I couldn’t get a answer that made sense of anything. I ended up buying 16 200ah liitokala cells for a few cents per WH.

Just found this in the litto site 180 ah and low temp bms and all

I am getting very confused by this posting. what is it you are trying to do and why are you messing with the 2 heating elements. First heating wateri with electrics is by far the most expensive and if you have an excess in PV as you said, why not using a smaller electric heater connected to...

And make sure your aluminum or magnesium Anodein the hot water haven’t dissolved totally, causes a lot of bad deposits in hot water lines .
