KYHT BMS Interface specifications CAN RS485 commands.

[Mike Davison]

I have 48v Lifepo4 batteries with the brand Deutche Technologies. They have a KYHT branded BMS inside (see http://www.kyhtbms.com/goods/show-135.html). I have tried contacting local battery supplier and the BMS manufacturer but have no joy in getting a response.
Does anyone have any information on the interface specs/ command protocols for this BMS. I have tried a few different command protocols to no joy. I specifically want to know the control commands so I can integrate into a centralised monitoring system. Anyone with information?
