Lets build and test the new (V2) DIY battery kit from Yixiang Power. This is a 51.2V (48V) battery great for solar backup and off grid storage. The kit in this video uses 314 Ah, LiFePO4 cells (lithium iron phosphate). Also, the BMS is a JK brand, 200 Amp rated with 2A active balancing. I perform a current test, over-current test, and capacity test. You will also see the full build and top-balancing function.
