I know I am not the only one wanting to write my own software to interface to the UPS. I am currently developing some software (not related to the DC UP at all) and I would really like to integrate UPS monitoring into this software as it would be very useful indeed. Your documentation states that you use a particular chip for power management, but that's it. Please can you provide details such as which I2C addresses...)

I understand that if the voltage is extremely low then it charges very slowly in order not to destroy the cells. When voltage is above 3V it charges normally. Am I right?)
  • 04:44, 11 February 2022 89.64.87.242 talk posted a new comment on X728 (Hello geekworm! I've been findin X728v2.1 an excellent product! Very usefull and great quality for the price. I forgot to turn off RPi on standby mode and it drained my cells down to 2,97V. The Cell is Samsung INR18650-35E which has a 2.65V of cut-off voltage and therefore you rescued my cells! But when I plugged DC-Jack with 5,01V to X728 it draws only 0,15A current. So It's charging very slow or not at all. One of four battery diodes is blinking.)
