JBD UART USB module

[wtfg]

Has anybody change the sleep time on a JBD-AP20S003S-L20S-200 or other JBD BMS with UART to USB module?
What I want is to turn it off, so it doesn't go into sleep mode.
I set it to 0 from 65000 and the relay just goes off and on
Now I set it for 30 days, but would really like it off.
The problem is when it goes into sleep mode the voltage across the relay drops around 2.5 volts causing my Outback Radian to go into charge
Thanks

Setting for 30 days did not work
The max is 65000 or 18 hours
I still would like the BMS to not go into sleep mode or Fet ctrl time set
Any ideas?

Thanks

@wtfg , did you find a solution?

From the manual it seems that regular communications will assist to prevent the JBD BMS from going into a sleep condition:



It might be worthwhile to connect a PC with serial communications to the BMS and see if it still goes into a sleep state.
