do you have a bench power supply?? I am getting the impression that you think the supplier of the cells balanced them...???? suppliers of these commodity cells do not balance the cells.... they normally are shipped at 3.29 volts but this is not balanced for a correct top balance.....
I am still not sure what is the problem with your cell 15 ...>>> is it a bad cell or did the Daly BMS not shut off the discharging ?? for if (I assume) you have an inverter changing the DC from the assembled battery to AC for use to power other things....
I hate the word assume because one can be so far off on what the actual situation is...
please forgive me for using the word. (assume)
the cells need to be top balanced to 3.55 before assembling the battery pack, and most people top balance all the individual cells to 3.65 volts per cell before assembling them into the series-connected battery...(highly recommended)
the top balancing should be done by you with a bench charger....
you may already have one.... I hope all works out for your cell.... especially cell number 15 seems to be the problems cell...
did the Daly BMS malfunction?
I do not use a Daly BMS....
let me know how cell 15 is reacting to the charge when you pull it out of the assembled battery to charge it by itself.
i am interested in how it progresses.
