I am getting aquainted with the Daly BMS app using a Daly clone BMS that I bought in 2021.
I've since taken my 24v, 200ah bank apart in preparation for my 6P8S bank.
Before I try to tune the 500amp Daly BMS on the full bank, I wanted to familiarize and tune a smaller BMS on 8, 3.2v cells.
Two of the settings on the 'Cell characteristics' menu are a challenge: Balanced Open Start Volt and Balanced Open Diff Volt. From what I have read, I gather that for my Lifepo4 cells, I should select 3.2v and .02-.03v respectively.
For those with Daly or with more Lifepo4 experience, what are the recommended settings? A few other settings I am using currently (by menu):
Protection parameters:
Cell volt high protect 3.6v
Cell volt low protect 2.8v
Sum volt high protect 28.8v (3.6*8)
Sum volt low protect 22.4 (2.8*8)
Diff volt protection .02V
Chg overcurrent protect 50A (max continuous charge voltage recommended by CALB for the cells)
Dischg overcurrent protect 100A (max continuous discharge voltage recommended by CALB for the cells)
Cell characteristics:
Type of battery LFP/LifePO4
Rated Capacity 100AH
Cell reference volt 3.2V
Sleep waiting time 3600s
SOC set 100%
Balanced open start volt 3.2v
Balanced open diff volt .03v
Temp protection (advice welcome):
Chg high temp protect 65C
Chg low temp protect 2C
disChg high temp protect 70C
DisChg low temp protect 2C
diff Temp Protect 15C
MOS temp protect 47C
