Hello everybody,
I invested in ten 10.24kwh batteries from an Alibaba dot com company. They provided loads of document for MSDS safety reports, custom clearance etc. Non of the documentation if fully matching the product number SGTNPCDJ17001, but it does match the model 200AH 51.2V that is on lots of the CE and other reports. One of the reports mentioned the Cell model 电芯型号: IFP28148115A I checked this before purchasing and thought great Li-FePO4 cells.
Now one of the batteries has a broken cell01 and turns off by itself after a self-check, i can not use the battery as is anymore. I opened it up and I do not see anything that looked like a IFP28148115A cell but there are 64 cells combined to 16 cells in the pack.
How to proceed? Advice? Do I just take it fully apart? It seems that the cells are all joined to one big PCB, with a bus bar....
Can this still be a Li-FePO4 as written on the front of all batteries?
