Exactly ... The Chargery part of the thread has been lost ... The discussion has been sidetracked.
Experiences or opinions on the Chargery BMS?

I'm taking my words back:
I had defective BMS board that was draining one cell constantly, also it caused incorrect voltage readings. Don't know what happened to BMS main module..
After purchasing new unit - all voltage diff cell reading within 5mV.
What unit did you have was 8T,16T, or 24T?

16T
I have someone else who seems to have the same Issue. I am going to start testing them before they ship when I can. Thanks. I have not heard of this problem with the 8T's Thank you.

I've got my 1st BMS faulty right out of the box, then another person contacted me about this BMS with same issue. My intention is find why it's happening and potentially solve this. No intention to spam.

let me know what additional info needed. I performed one more test, when battery was fully charged, then charge/discharge was disconnected and only BMS was connected to battery, after few days it went out of balance.
Same test but without BMS - batteries remained balanced. I don't have tool to measure internal resistance, but this test tells me that pack itself is fine. Please let me know what other info is needed to identify problem.
You can start by saying its your video not leading us to think it is someone else.
The Chargery can measure IR. Like I said on the other thread put a clamp meter over the balance leads and show how much energy is passing through.

Seems like it would be better to post the video in one place and link to it ..... as craig said, it's pretty disingenuous to post the video without indicating it is your video.
Please decide which of these threads you want to keep active so people aren't having to post on each one.
I didn't like the Chargery either.
Not sure why it matters that you posted your own video. The statement you made may have lead these guys to think you found a bad review not that you actually did the work and the bad review stands just the same.
What was your problem with the Chargery? And what did you find that was better?
The settings are clunky and not always intuitive. I had issues getting the current calibrated and the balancing seemed too slow. Also it does not balance below 3 volts. I know I know a pre bottom balanced pack is best but if I am utilizing something like the chargery i would like it to cover all the bases.
I switched to a very basic active balancer and installed voltage displays on each battery. I have a regular BMS too, but haven't installed it. The LV2424 will shut down if pack voltage is below 21 volts and I have a 100A DC breaker so no much worried about over current or undervoltage and my basement will never get to a temp low enough so the active balancer is all i really needed.

Not quite sure what your point is here, was the pack charging or discharging at the time? Internal resistance changes throughout the state of charge.
Honestly i am not sure how good the chargery IR test is but as you can see the cells are not matched at all.
IR must be tested during load with properly calibrated shunt.
