Is there anybody out there actively using JK-BMS balancers cascaded? I knew of their capability and build a 64s battery with currently 3 JK balancers. But now I noticed the following: When the battery pack is being charged or discharged, the voltages of the "cascading cell" differs a lot...

@TedH I guess, this would be the wrong approach. The TTL protocol seems to be "monitoring only" and reading your post this is also the only thing you want to do: get information to display it in VenusOS. The project here is used to communicate bi-directional between an inverter/charger and an...

Just to report my mistake: I obviously ran into a known issue, where the internal SJA1000 of ESP32 is running at half speed only. So I only "thought" to be able to communicate at 500Kbps, but now I verified with a Logic Analyzer, that it is running at 250Kbps with the 500Kbps setting! Still, I...

You may follow the provided link to a project, that enables a web interface to act with the CAN bus. Send messages and see the replies. You can use this on a second ESP32 to watch your CAN bus or simply verify the communication with single devices. Write me a PM if you are interested and have...

Peter, you are going to build a HV battery - the current firmware is not yet ready for HV. In the meantime you may test your BMS and Balancer communication. I don't have any suggestion for RS485, but with esp32-can-iot I found, that my Balancers (JK-DZ08B2A24S-CAN) are communicating at 500Kbps...

You may evaluate without an app key, only the maximum charge and discharge current is limited to 1A. MrConstantin decided to not provide any keys for free after 15th of November...
