Hi, yes i have solution. it is very simple i updated the firmware on my board via rs485... and I don't understand, here some write that they have received an update, but no one shares, why are you here? rhetorical question... have the firmware file and instructions attached (v2.4) whatever...

This is OK

Hi to all, sorry for my google translate :) I also have this BMS, with 13s2p Li-NMC (LGx-e78). Unfortunately, my easun smp 5k inverter does not support work with CAN/RS485 (although it has connectors and IC's on board...but build in firmware is not support, of course, the support of EASUN does...

If you connect a second battery in parallel, whose voltage differs from the first one, the current flow between them will be limited to 20A

Не ви у мене в ютубі питали про підключення ? Кілька тижнів тому. На рс485 пару з даними а/б перекидали?

unfortunately support directs me to a seller who does not respond. I was wrong, my firmware version is 1D (21 it was the display version), and I read here that you have the firmware version 24 file, maybe you could share? thanks in advance

виклав рішення. Поділетеся файлом моделі для 3д друку ?

Calibration :) if you have different voltages on battery and on BMS. And currents too
