16S JBD BMS in parallel

[squowse]

I want two 16S batteries in parallel, each with their own BMS. I like the JBD bms and wish to use ones with both UART and RS485 connections. I want to use the UART for the Bluetooth and RS485 for Victron Venus OS using louisvdw dbus driver.

The model i am looking at is AP21S004. The only information I can find seems to indicate that this BMS is not suitable for connection in parallel. I cannot find the manual or datasheet though.

Generally speaking when it's stated "not in parallel" that usually refers to multiple parallel BMS on the same battery.
