Sounds good! Thank you for the response!

How have you guys liked the combination of the EG4 equipment and the BlueSun solar panels so far? I am looking at using them for my own home solar project, as well. I had a solar installer here tell me that this stuff is mostly junk, but I don't believe it.

anyone?

By the way, I would likely use them to make 12v batteries using EVE 304AH LiFePO4 cells or similar.

Has anyone used one of these plastic boxes from Docan Power in a battery build? I am curious to see photos of how things were arranged on the inside. Also, will the battery cells with laser welded terminal studs fit inside them without issue or modification needed? Docan Power Plastic Box

Yes. See post #6. https://diysolarforum.com/threads/docan-power-return-issues.38394/#post-501636

I have built two 12v LiFePO4 batteries using the Overkill 120A BMS devices and some 280AH EVE cells. They work great. Now, I am in the process of building two 24v batteries from 304AH cells purchased from Docan Power. I see that Docan sells a couple of JBD BMS devices - one 12v and one 24v...

After many months, I finally unboxed my 16 cells to check them. I have been very busy and have not had a chance to look at them until now. I am very pleased to report that the cells appear to be in perfect condition. All of the voltages across all of the cells are within .001 of each other...

I finally received the 16 battery cells yesterday which I ordered on Jan 7, 2022. I have not had a chance to open the boxes and inspect them yet, but except for one minor tear in the corner of one of the boxes, they seem to be in very good shape from the outside. I am looking forward to...

Okay. Thank you all for the responses. We shall see how it goes.

Thank you for the responses. I understand it can be slow, but it is hard to understand nobody knowing where the items are, and 16 days after being told they should be at the port, there is still no update. How come there isn't better information about where the products are in this day and...

I ordered 16 EVE 304AH battery cells from Docan Technology on 1/7/2022, and they still have not arrived. Has anyone had any issues with not receiving battery cells they have paid for? Sandy Zou is the contact, and she has responded to all of my messages. Our last round of messages stated that...

I have been thinking this too! Thank you. I started off on this journey several years ago when I bought two 6v deep cycle lead acid batteries. They gave me the ability to have many hours of light and to charge devices or use my PC or other devices, if needed. However, the lead acid...

Sorry, I didn't realize there had been any responses yet. I am interested in what would be better for my situation - 12v vs 24v vs 48v. I am seeing that there are not as many options for 24v equipment as there are for 12v and 48v equipment, it seems. One of my requirements is going to be...

Well, I got curious today and examined the Heltec device and the cabling. I saw no visible damage to the Heltec and the cabling seemed fine so I thought I would do a test while I am waiting for the replacement to arrive. I put a ring terminal on the wire coming off of pin 5 and connected it to...
