0:00 Reject cells failed QA and have different characteristics than other reject cells. 0:09 of you buy 10 reject cells and charge them all to 3.65v, then connect in series and discharge them, the voltages will be significantly different 0:16 most people will use active balance and mask this problem, but you can also avoid it by setting max voltage close to 90% SOC 0:20 the charger is the original Lead Acid 60v charger, so the ANT will be telling it when it can charge 0:56 OVP is set at 3.38v and OVP release is set at 3.35v.

But it varies depending on the manufacturer and temperature. 1:21 most of the energy is between 3.20v and 3.35v, very flat SOC curve, so it should never be balanced in this range should be above 3.35v 1:25 if using reject cells, don’t balance it at 3.65v either. 3.35-3.40c is a good place to balance. 1:40 mine is set to only start autobalance when above 3.35v, and it will run until differential drops to 0.000v. 1:56 as soon as i plug in the charger you see the light turn red and the ANT app shows -2.80a (charging is shown as negative values) 2:08 you can see it already started autobalance automatically because of the settings I gave it. 2:15 The ANT has a red LED that lights up for each cell group that is being bled to balance the pack. 2:29 this balancing is false balance based on voltage surge of reject cells being so different.

Once it reaches 3.38v the charge port will close and the voltage surge will subside. 2:44 The app shows UnitOverVoltageProtect has kicked in and closed the charge port. No charging or regen will be allowed in if this is closed. 6:08 balance current can be set higher to speed up balancing but it should be set as low as possible that still achieves balance. 20ma ideally 8:24 the balance resistors make a lot of heat if current is set high, this is why you want it as low as possible but still does its job. 9:14 fully balanced so all bleeding stops.
Can you make a screenrecording of the ANT app and scroll through the main page top to bottom, then the settings, top to bottom of each. Then I can watch it and see whats wrong. Make sure it’s NOT for kids because that needs a different app and I can’t comment on the video. Make it longer than 1 minute so it’s not a short. Short has no timestamps. Then I can watch it and say “the setting at (TIMESTAMP) is wrong, change that to….”

Hi IMHO,Why does my Ant BMS say SOC_LowLv1Warning and SOC_LowLv2Warning? And at SOC 0%, please help master
