It should also disconnect on cell over voltage. If the BMS is set up correctly, and actually does what it is told, all that should happen is the battery capacity falls over time as the cells get progressively further out of balance and the BMS top / tails the amp hour rating. No cell should ever be observed below 2.5V or over 3.65V. To see cells at 0.2v says something has gone badly wrong.
i sent him the messages in you responses to the Daly BMS...
and also sid's and dickson's ....
so i hope he has some success....
he was a new to the lifepo4 and i think he only had 2 posts when he reached out to me...and i am not familiar with the Daly BMS but he may get back to me with more details...
i am sure he will thank you for providing him the information...
yes as i see many have problems with the elcheapo chineseium products...
i would like to avoid if possible....
With some precautions, yes. As they are using the TLP172GM for output isolation, you can literally put the appropriate control output on both SBMS0 units in series (due to the 350v rating on the TLP172GM), and use the result as a control signal indicating BOTH SBMS0 units are ON. Something like this
thanks,,,,
i wish i could do diagrams but still have to do it on paper....from the stone-age in some of my abilities i think sometimes; or at least never worked with the right program to do them on the computer.😎
