1 GW
Particular Model
16S 48V 40A LiFePO4 ....... (simple, no uart)
Exact link where I bought 15 of them ..................(not prime, shipped from China)
https://www.amazon.com/gp/product/B0876ZT5M1
I have already posted all the positive things I have to say. The BMS are amazing in every way but one... the output fails to short (at least on this batch). Classic Counterfeit Mosfet overheat-to-failure. Once in failure, the device acts like a diode passing any current that comes along, while dropping 500mV and producing lots of H E A T
HOW TO DETECT FAILURE MODE
* If it runs super hot at mid to high current
* If it lets you run past LVC
* If you can measure Diode from Blue to Black wires (anode facing out) while powered off
Now onto the teardown, if you want to know more about what lead up to it, ask.
