My LCD display is not level, it is rotated about 5 degrees CW. The wiring is inconvenient, I needed 10-30V to power the shunt (I connected it with aligator clips to my 8s280AH battery terminals), then the shunt itself needs connections from the 1st green screw terminal, and from the first shunt bolt, again to the main battery positive and negative. ![]() This is on the 2nd screen, but within 2 seconds it reverts back to the main screen. The default screen shows Voltage, Amps and battery %, but not the discharge power or AH. The 500A model I chose has a nice big shunt, but the (display ?) resolution is 0.1V whereas the smaller shunt models are 0.01V (Despite the manual saying the AH capacity range is 0-2000 kAH) ![]() The maximum AH for the battery setting is 6500AH, which is only 90% of the capacity of 8s280AH cells. The slots for the cables will need to be enlarged with a dremmel. The top lid is full of holes and they're not even the same size for the two shunt bolts, which have unsecured hex bolt heads against the underside of the PCB. The temperature sensor socket is directly under the path of the right negative lead I have doubts it will even fit with the lead clamped down. The plastic top cover has cutout slots for the negative cabling to come out of the bottom, the cutouts are too small to fit any 4AWG or 6AWG crimped lug, nor even my 200A BMS's lead lug. The shunt unit feels heavy and pretty sturdy, although the design is stupid. My Juntek VAT 4300 just arrived today after maybe 2 months wait from aliexpress.
