China Battery BMS

Fork from https://github.com/mytest4u/BMS

Warning Use at your own risk, especially the firmware!

Facts:

BMS: DR01 or DR-JC03
Capacity: from 60Ah, up to 300Ah
Where to buy: all over Aliexpress, like "PAPOOL LiFePO4"

Connect to Victron Controller

First of when only DIP 6 is facing upwards, it's recognized as a "Pylontech battery" and the charge controller will not see any battery details like cell voltage, temps - so avoid using this mode.

Cerbo GX

Buy a cable from Victron or build it yourself: Cerbo GX: VE.Can to CAN-bus BMS cables manual. DIP 5 & DIP 6 up, conenct the special CAT cabel and enjoy the battery details.

Venus OS

Venus OS on Pi: CAN Interfaces

Victron Venus OS provides the Battery Can Bus drivers but not the Hardware port. So just get a Waveshare RS485 CAN Pi HAT and connect GND, CAN-L (Low) to Pin 5 and CAN-H (High) to Pin 4. There are certainly other options for non-Raspberry Pis Venus OS setups. So we do not need BMS support in dbus-serialbattery / issue support BMS DR-JC03.

Battery Stack Setup

Connect the master pack with DIP 5 and 6 facing upwards, as indicated in the Victron connection instructions.
The pack will be recognized as an "LFP battery" and you can view the voltage of the highest and lowest cell under the "Details" section.
You can also see the number of packs online and if there's a pack preventing charging/discharging.

How to update the firmware

Connect the PC and battery using a cable, ensuring that DIP 1 is turned ON for PC connection.
Make sure to install the necessary RS485 drivers for the connection to be established.
Open the "DR-Application.exe" application and keep the window open.
Open the "index.html" file located in the "dist" folder using a web browser.
On the "Help" tab, change the language to English and enter the password 666666 if prompted.
In the "Settings" tab, select the "Update" option, choose the bin file, and initiate the flashing process (you will know it's working if the green LED on the battery is flashing).
