New lifepo4 system, choosing a BMS for easy system integration

[Gillw]

Hello all,

i am building a new system from scratch. 24 volt, probably using 8 x 280AH EVE cells or similar, rated to around 200 amps. I’m trying to decide which BMS to use.

I am not really wanting to use an app to monitor the battery, I’d rather extract basic status information using an Arduino or similar device and display it on a small LCD, ideally using Bluetooth, but wired serial is ok if I have to go that way.

Can anyone recommend a BMS that is simple to integrate in this way?

Thank you,

Matt

Both the JBD and JK BMS have an optional display/screen, if that's all you need.

AFAIK, both can also be integrated in Solar Assistant and in Home Assistant (with additional HW).

Have a look at these repos:

GitHub - syssi/esphome-jk-bms: ESPHome component to monitor and control a Jikong Battery Management System (JK-BMS) via UART-TTL or BLE

There is also an Arduino library for the JBD.

Thank you, great links. Like the look of the BLE support on the JBD.
