So are you saying you are ok that you only got scammed out of $50?

If you had a boat. :)

So, you can solve this problem in about an hour and install a new converter [I would go with something that could push some serious amps] or spend years and thousands of dollars fighting a large corporation. Have at it, but, I would just purchase a new converter with an old school switch...

Cheap is not an insult, sorry you take it that way.

And some people are waiting for months and never receiving a product. So we are comparing apples to apples, the JBD BMS's I purchased were around $80, none were even close to $52.

It's what companies do. They buy a product and sell it at a profit. That supports the staff and the service that they provide. I doubt if JBD has a support staff if there are any problems. We all should look at ourselves and support the local community. At least the good ones. I get if you are...

If I recall, Andy at OGG posted a video using a standard [vs metric] stud and just screwed it in. It was slightly larger and no taps were used. Of course, I would not trust my memory but a quick search would allow you to watch the simple repair he did.

I cannot see why you would want to run a cable that could not supply 300A to an inverter that can produce 3000W. I understand copper is expensive, but buying copper that will not be used what so ever is even more expensive.

I look at stuff like that as it can run 'up to' 50A or 'up to' 30A. When it comes to heat being generated, I like knowing watts. For some reason, I can wrap my head around watts as heat vs amps.

I rarely ever lean towards lighter duty. I would rather see a item work at 60% to give you your needs vs 100%. Means nothing and it's all mental, I get it, but it still does not change my mine.

Seriously? You spent time opening an ad with prices that low and opened a thread asking if it is worth it?

Couldn't you just check the actual weight? I would think there would be a slight difference.. Without a doubt, buying batteries can be a crap shoot, but isn't everything that way now? There are ways to keep the odds in your favor. Usually, it costs a few dollars more.

I purchased mine from this Aliexpress company. Twice! I got the BMS in about 3 weeks. I wish I can say their returns are easy, but there was nothing wrong to return. Just works. Of course, there are some vendors that will steal from you, but there are some good ones and if you are not in a...

Everyone has their preference. If you research, you will find what makes people feel good. Right now, I do have a Daly 200A, but I will be replacing it with a JBD 200A to match the other two batteries. People can be tribal on what works for them. It's ok if people are different. In the end, you...

Do as you wish, but if you have not purchased a Daly, there are cheaper/better BMS's out there.

So, you open a thread to bad mouth the Chinese for lying and cheating, then you say 'Opps never mind'. We all get a pit in our stomach when things do not go right but as I get older, I tend to wait till I can prove that someone is wrong before I start casting stones. If I were you, I would at...

There are 8 billion people here on this planet so there are plenty of customers to prey on. Out of those people, many of them are gullible. Many of those are too lazy to do anything about their money being stolen so they right it off. There is no end in site for potential clients. As clients...

Just saying if you have to keep filing disputes, you really need to blame yourself. We all have some bad luck and make bad decisions, but when you constantly are making bad decisions, you need to start blaming yourself. We all need to stop being so cheap and gullible. Accept that good stuff...

I think the OP wants a 4s and that BMS does not seem to offer a 4s version. I will second the idea of multiple batteries. Although I do not know what the odds that the rating of BMS's are reliable, I would always take a Chinese spec and drop it by at least 30-40%. Daly makes some high amperage...

Did you try the organic/gluten free stuff? It's not too bad.

Nothing I can help with. I'm probably newer than most folks here.

Just saying, whiskey is nasty and marking it as cleaning alcohol would be a fair assessment. :)

There are plenty of 12v panels that are push out around 19-20v. Yes, the DC50S has it's limitations but doesn't everything have specs you should follow? The product is not for everyone, but that is why you research and find out if this product is worth it for your project. Not many MPPT units...

Not too confusing to me. I just looked at mine and looked at my options. I picked single cell since it seemed to fit my set up. You could just press all the options and see what goes on. I doubt if anything will get screwed up.

Sorry, I am the wrong person to ask the differences. They are blue. They are all about the same size. Two sets have welded studs, the other is a threaded hole. All three sets were purchased and I'm happy with the 3 transactions. The Eve cells had a good QR code. The CATL, I do not know yet...

They are 302 CATL this shipment and 304 Eve on the last two shipments. This set had studs, the second Eve set had studs, and the first set were threaded. This set came from China because they did not have any in the USA where house. I purchased CATL because Eve's was not available. Would I...

I purchased CATL cells from Daisy at Docan and they came in a few weeks ago. Like the other two orders, everything was delivered properly, on time, and as stated.

I would suggest you find someone nice to find out how deep their holes are.

We all have opinions and can build a strong foundation to support them. I beg to differ. You will not find a lot of pages on the internet to support a $50 price. You will on Aliexpress, but the last time I checked, Aliexpress is not the only one on the internet. If it indeed took you a month...

I find it odd that a buyer does not shop around. When does that ever happen? Even when I go shopping for food, I look at labels and prices. Really? you believe the buyer has no idea what a fair price is? I get that they do not know what the manufacturing price is, but if the buyer does not...

Yes, if it would have been a price that is reasonable, then it would be different, wouldn't it, but that is not how these scammers operate. Scams work because there are so many people that are cheap. Those are the same people that bring a doggy bag to an all you can eat buffet. Anyone that has...

In this case yes, without a doubt. Mice get tricked into getting the cheese in a mouse trap. We humans should be smarter than mice. When it comes to cheap deals, humans take the cheese and then blame it on others. Smart people look at it and say, 'That's a trap' One look at the site and smart...

It takes two to make a scam successful. The scammer and scammee. They way I see it, those that would take that bait are more liable than the scammer. If there were not so many cheap people, the scammers would not be so successful.

Doesn't the stud stop turning once it bottoms out? If that is the case, why need to mark it? When I glued mine in, I turned them in by hand and once they bottomed out, just a tad bit tighter. It's not that difficult and it sure seems like people over think this. You only need a small bit of...

Tape on the surface before the gluing or use conductive silver epoxy. Expensive, but you do not need much.
