    Must Read: EMF (Electro Magnetic Field) or leaking current/ voltage, and why you need to be aware

    I seriously didn't know better when I said that. I wear shoes and I am very careful when working with electricity.

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Thanks for the video Ray. Someone recommended the dowel like you have but I had trouble getting the sandpaper to stay on. Now that I watched your video I will make it work like you did.

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    That is some valuable experience. Loosening and tightening the nuts over and over is likely to cause stud failure. Your cells are also more likely to shift around in your RV than they would sitting on a self in a stationary setting. The aluminum that the studs screw into is soft. I used a...

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    I just used plywood on the ends and threaded rods. I torqued them to about 5 inch lbs at 3.3V then charged them to 3.4V and re torqued to 10 inch lbs. Cycle them a few times and re torque to 10 inch lbs when you get to about 3.4V. They will flatten out some but you will still be able to tell...

    My EVEs had some bloating until I put them in a restraining fixture and flattened most of it. I think they will be fine.

    Sol-Ark problems by David Poz.. anyone else?

    I am a little surprised that people use the Solark for off grid. Its strong point is being able to juggle many things at once including the grid. I plan to add more panels and AC couple them to my Solark. That might help with the issue David was having. I am glad people are making videos about...

    Compression question for EVE LF280K

    An inch pound torq wrench will work. Just set the torque when the cells are fully charged. If you set it when they aren't fully charged the pressure will increase when you charge them. In my opinion, the compression is just to keep the cells from bulging too much. If you use springs it is less...

    NEWS: Florida legislature considers ending solar net metering (Nov.23.2021)

    A lot will change in 10 years. I guess it must be upsetting to people who project their payback over 20 or 30 years.

    NEWS: Florida legislature considers ending solar net metering (Nov.23.2021)

    In 10 years I'll start using my batteries more. I just use net metering because it is a cheap and easy option. But I will continue to work toward grid independence. Net metering seems too good to be true.

    Conservative settings

    You are likely to harm your battery with that charger. I imagine someone else has done what you are trying to do.

    Conservative settings

    If you want to be conservative, do it with the charge controller. Set it to something like low=3.1, high=3.35 (convert to 12, 24 or 48V) Try it and if that gives you what you need then you should be good. The BMS protects the battery if something goes wrong with a single cell. Either of those...

    What Can I personally do to help against climate change?

    This thread is much more civilized than the other climate change thread. If people want to do something about climate change, they need reliable information. And people should be able to interact like adults. Part of the reason I decided to get solar and drive EVs is because I want to help the...

    Beware @Michael B Caro

    I am not a Facebook member so I can't see the posts. And I don't know Michael. I believe you when you say people who deal with you will not end up like people who dealt with Michael. Michael thought he could make some money playing middle man. But like 99.9% of new business adventures, he...

    The vaccinated are more likely to catch Covid

    "the-vaccinated-are-more-likely-to-catch-covid" So, I guess you are saying that the vaccinated are more likely to catch Covid. But the vaccinated are less likely to die from Covid.

    Beware @Michael B Caro

    That group was created 2 years ago. I'm not so sure you can call that looking for new business. My guess is that Michael got himself into a situation that he never will be able to fix. He never set out to do anything dishonest

    enphase iq8+ powerwall

    I assume you would like to use Enphase micro inverters with a DIY battery. That was my first question when I came here. I ended up using a hybrid inverter and no micro inverters. In the future, I plan to add some panels with micro inverters and feed them through generator input of the hybrid...

    Global warming is real, why only in USA is there denial ?

    You make it sound like people should just give up and die. Humans are pretty stupid but they don't give up that easy. I will continue to try and do my part to improve our chances. Have a great day anonymous

    Global warming is real, why only in USA is there denial ?

    Yes, I agree that it isn't worth the effort to make and deal with a trailer when you find a reasonably price charge close by. And since fast charging (over 40A) wears out the batteries it probably doesn't make sense to own a high speed charger. In the rare event that I want one, I can just pay...

    Global warming is real, why only in USA is there denial ?

    I found his video. I have a grid tied system and I plan to install a 40A charger. That Rav4 Prime gets good reviews. But I will probably buy another fully electric car or SUV. I am surprised no one has made a little trailer to pull a couple of 48V batteries and an inverter to extend the range.

    Sol-Ark 12K Parallel Stacking setup.

    Four 280Ah 48V batteries I disconnect the AMGs then connect the LFP I charge them to 3.4V during hurricane season. otherwise I leave them at 3.3V There is no reason to keep them connected. And they will last forever disconnected.

    Safety certifications needed to get a LiFePO4 battery permitted?

    Do you mean as part of some kind of permit package? People are allowed to use gas generators with extension cords overloaded. That is probably more dangerous than a Bluetti or Jackery. Though I don't have experience with battery generators like Bluetti and Jackery.

    Safety certifications needed to get a LiFePO4 battery permitted?

    Safety certifications needed to get a LiFePO4 battery permitted?

    Yes, AMG is the default battery type on the Solark. I have connected my DIY batteries to the Solark but I have no reason to keep them connected. I will only use the DIY batteries if there is an extended outage. Outages are so infrequent that my batteries will last forever. When they came for...

    Safety certifications needed to get a LiFePO4 battery permitted?

    My area is at something like 2014. But they would not allow me to assemble batteries with non UL listed cells. When I asked about it, my local authority immediately said they would never approve any type of DIY battery made from non UL cells from China. They knew exactly what I was talking...

    Global warming is real, why only in USA is there denial ?

    Though it has nothing to do with climate change, religion, lawyers, politics or education, I am preparing for retirement. My house will be paid off soon. I bought my wife an electric car and I installed solar. And I don't have payments because didn't borrow the money. Part of the reasoning is...

    How to buy cells

    It has been sad watching this site lately. It seems like the scams have gotten out of control and Michael B Caro got caught up in the middle of it. When I bought 66 Eve 280Ah cells, over one year ago I was a little disappointed when a few cells didn't test for full capacity. But after seeing...

    Sol-Ark 12K Parallel Stacking setup.

    I started with 100Ah of UL listed AMG for my Sol-Ark 12K. It won't last very long but it allows me to use my Solar when the sun is shining and it gives me some uninterruptible power. My 1000Ah of non UL LFP will only be used if the grid goes down for a long time.
