This is a simple Unboxing and First Impressions of "EVE" 230Ah batteries I received from Doncan Technology (Shenzhen) Co seller
@Amy Zheng. Purchased from their TX warehouse shipped to FL.
I do not pretend to be as informed and knowledgeable about LFP batteries and their purchase as many people on this forum. I first learned of these sellers
Here in this thread. I ordered these cells by contacting Amy Zheng directly on Facebook Messenger. After a little discussion, and being very through about my specifications I placed the Order Saturday Sept 25, 2021. The cells were ship from their Texas location. I got tracking numbers the following Tuesday and received the cells today, Thursday Sept 30, 2021. Turn around time was supper fast.
First the communication before and after the sale has been excellent. Amy was very responsive to all my concerns and questions.
- Shipping / packaging was almost perfect. The only thing I might have wished for was protected corner ends for the boxes.
- But they were packed so well in the boxes, it really did not matter.
- Only 1 box had very slight shipping damage that did not penetrate the inner foam.
These were sold as new Grade A cells and From all indications these are new and look cosmetically to be Grade A cells. I will start Top Balancing and testing in a few days.
1. They all look in perfect mint condition. No Dents, Scratches, etc. Shrink was nicely applied.
2. The voltages test out at 3.293 - 3.292 for all cells
3. I did weigh them and they weigh between 4134g - 4205g (but I am not sure what weight would tell me)
4. Each cell is labeled with a white label. Each says the same thing: 230Ah / 3.29v / IR 0.23m
5. QR codes are in tact and can be read
6. Studs are all clean, never connected and look good
7. Hardware is adequate.
8. And while there is no indication they are actually EVE cells, The cells DO match the mm size spec that I found on a spec sheet for actual EVE 230Ah Cells. (but I did not receive cell instructions, spec sheets or test data)
Yet there are a few things I do not understand, so maybe someone here can shed some light on these things.
All the batteries Look Brand New, but have 3 concerns (and I am not sure they are that big a deal).
1. There is nothing on the cells or in / on the boxes that indicate they are actually EVE 230Ah cells. The box simply says "E230"
- cells are supposed to be EVE 230 cells
- There is some label the size of a shipping label that was cut off the side of each box (see pic below)
2. I had asked for data and testing sheets.
- there are no data sheets included
- there are not spec sheets included
3. There is some very slight swelling, some worse than others, so that cells do not fit exactly tight together. But nothing is the bad. See pics
Over all I am very happy with the speed and shipping and the look of the cells. Just wish they indicated they were the EVE 230 cells I ordered.
Here is the readings from the cells. Almost perfect Voltage. And their weights. But I do not know what they are supposed to weigh or if those weights ranges are acceptable.
Here are the pics of the Packaging. EXCELLENT ... But What was the label that was cut off. I assume it was the shipping info from China to their warehouse
