A few months ago, I bought 3 DIY battery boxes and 48 REPT 320 AH cells from Yixiang off of Alibaba, this has to be the worst decision I have ever made. The boxes seem decent, not as impressive as Andy from OGG made them seem, however the cells re HORRIBLE!!! None of them are matched whatsoever! Not only are the capacities different ranging from 318 AH to 334 AH, the curves are different so it is impossible to top balance these during normal use as the 2 amp balancer in the JK cannot keep up. When I first received the cells I capacity tested all of them and matched them up in a battery box and put them in service. After a couple of weeks I noticed in the middle of the day I would have 300+ mV deviation between cells when charging from solar because the BMS would stop charging from a cell over-volage. I am now in the process of capacity testing all of them again trying to get Yixiang to replace the cells but they are now telling me the EBC -A40L is an inaccurate tool and the cells were tested and matched at their warehouse. After less than 30 cycles, some of these cells I've tested so far have lost almost 10 AH, but none of them are doing so equally! PLEASE stay away from REPT and YIXIANG!
