When I received my second battery pack from batteryevo there were issues with one of the battery cells. I called in and requested support. After further testing it was determined the cell was indeed faulty. So I sent the cell back and the wait began. I did notice however how the cells were all bloated. When you receive the cell pack they are all nicely strapped and compressed. Anyway, I received the battery cell replacement that next friday and of course it came in the evening hours. I quickly tested them out and the issue still was not resolved. Who can believe that 2 cells in a row would be faulty. I tested this out multi times through the weekend, shifting the newly replaced cell to a different position in the pack and even different BMS and the charger would not charge and that particular cell, no matter where it was in the chain of cells would race a tell the bms to stop charging that it was full when the other cells were no where close. Still hard to believe when they say the cells are tested 3 times to be to spec. Maybey they do but then fail to test when they have the singular cells as a 12volt pack. Anyway, my impression is quite mote since they stated they would not be selling or holding them any longer. Though after they sent the third one, which they said that would be last one sent it was too expensive to send. I did ask, isnt this under warranty and I sure didn't want to receive something not working as promised in your web site. In fact it is hard to test to see I can only guarantee that they go to 135 ah -- not the 150 because their bms cuts off at 90% charge. I also learned they were getting frustrated by this community as well as others and their questions they would come to them with. Its hard to imagine that this being one of the more expensive components of the project that people would not have questions. Leaves me with questions of their credibility for sure.
Anyway, long story short I found another company and am testing them now. Its the 18650batterystore adn overkill solar bms. Here you will see the outcome and definately impressed with thier products. I will leave a link to both down below and hope you will visit. I was not promised anything from them but I do promise you if I find good products and reputable here in the state side I will share.
As soon as the battery box comes in and the terminals ect we will be using this bms and cells to build a small battery pack self contained looking like a regular packaged battery for teaching/training purposes.
Stay Tuned...
