The 4S LFP 200A U 485 H comes with a work rs485 port.
When i say working. I mean i can read the config on a RPI with an rs485 usb dongle.
Also has a UART that you can connect a bluetooth module to.
Hi. Gave that a go and no change.
Also got bored and ordered a 150W one off amazon. Plugged that in and can pull 185W/14A!
I will see if I can get a refund on the other one.
Hi,
I have assembled a 4S 12V nominal pack using a 120A JBD BMS.
I have hooked up the capacity tester that comes on and works, however I cannot seem to get the Amps above 4A! which is around 50W. The unit is set to 185W max
When I start the unit up both knobs have been turned counter...
Ah. Really interesting. I get the same issue on a BMV-700 shunt. Wild variations in Amps.
I have “early” JDB 4S 200A BMS. The ones where the lugs are proud of the rest of the BMS.
M6 6mm2 lug on the positive
Negative is 120A JBD BMS with M6 25mm2 lug with three cables into it, via a bolt as a buss bar to a M6 6mm2 lug to the 6mm2 cable.
