Tattu 3.0 battery CAN communication

Hardware CAN Devices
1

Hello I contacted my supplier but haven’t received a reply, so I’m asking here.
I have two batteries: a tattu3.0 28000mA H53.2V and a herewin 36000mA H51.8V. They seem to support CAN communication, so I’m trying it out, but I’m having some problems.

  1. The tattu battery has six holes in the center of the terminal. Only four of those have pins inserted. Which are H/L and GND?
  2. To receive communication, do I just need to press the power button? Do I need to press a button multiple times to start, or do I need to send a command to start communication? Ideally, I’d like to communicate using just the battery alone (https://drive.google.com/file/d/1XGnn6HqyT103ocY5P7w-coyUxEWQcBd_/view). Has anyone successfully communicated using just the battery? Thank you in advance.

You will need to write a driver for the CAN protocol that is used in that series of batteries. It is not DroneCAN. We started creating a driver for it in 2022 but abandoned the effort since the protocol was a pain to work with. It was faster to help Grepow implement DroneCAN in their newer batteries than it would have been to get this protocol working.
