Hello All, in January I recieved Heyo/Daly RO5A-GA21 4s LifePo4 bms. I tied it to 4 x100ah Lifepo4 cells. which I use as a UPS for my monitoring pc.
everything seemed ok until I checked the cells with a meter and found a 280mv difference . For the last 2 days I have been trying to get this thing to balance without success.
What I found was first on the bluetooth app I cannot change "type of battery" which shows as "blank" and " cell reference volt" shows "3.6"volts. (second attached pic) Shouldent the cell reference volt be 3.2v?
and using the "PC BMS TOOL" the "battery chemistry" shows "liion" and the "battery chemistry id" shows "002F"
I think this thing is set up for lithium ion instead of lithium iron phosphate.
has anyone else encountered this?
I am hoping there is a different HEX code for lithium iron phosphate if anyone knows it?
I have sent questions and requests for info from the aliexpress vendor but have heard nothing back.
all the safety cutoff parameters seem to work ok. It is just the balancing I can't get working.
thanks
