BTW happy new years!
I might have failed that one up…. I am a Marine what you expect rainbows and Unicorn farts? ???Also make sure you are connecting 1-16, but also the last cable which is main cell positive, and the same as #16. The wiring diagram is very specific!
Nay, my Neey 10A is one of the new model which doesn't have the last pin B+ if you check the picture link at my first post.Also make sure you are connecting 1-16, but also the last cable which is main cell positive, and the same as #16. The wiring diagram is very specific!

Nope, I am using 16s cells. The pin B24 is not connected to 16th main cell positive.Neey 10A active balancer help needed on wiring (No B+ pin? New model maybe?)
My Neey 10A active balancer finally arrived just now. To my surprise, this model doesn't have B+ pin after B24. How do I install this particular Neey 10A balancer on my 16S Lifepo4 pack? I understand that B- is connected to first negative and B01 - B16 will be connected to positive side of cell...diysolarforum.com
It still uses the last pin on main cell positives though, right?
Gotcha, I understand nowNope, I am using 16s cells. The pin B24 is not connected to 16th main cell positive.
Now I am lost Lt Dan! I got bit in the ass!Gotcha, I understand now
Hello Ashley,Darn it. The 10A balancer beeping and red LED flashing non-stop again.
View attachment 192809
Based on the indicator status I found, the red flashing means "resistance of the equalizing line is too large".
Checked each Lifepo4 cell internal resistance, all around 0.18ohm.
Checked the wiring harness resistance, all wires fine 0.01ohm.
What exactly is wrong with the balancer. One day it works, another day it doesn't.
Any idea guys?
Hello Ashley,
I've had the same problem with this balancer: a fairly new device and sometimes it would stop working altogether. When I restarted the box it worked fine (green lamp + blue lamp), but when I connect via the Bluetooth it starts beeping and red LED. I have tried many things and now seem to have it under control for at least a few days and 3 rounds of full charge with balance. I had contacted the supplier who gave some tips, but it seems to me that the voltage is too high when the pack is fully loaded.
My steps:
- make sure your phone doesn't reconnect (passively/in the background) to the Neey (close app, I had connections from 2 competing phones).
- now discharge the battery as with normal use, I stopped discharging at about 60% capacity (of a 48V pack).
- Now disconnect (2 connectors) the Neey from the battery and leave it disconnected overnight.
- adjust maximum voltage of your battery to 55.2Volt. I was still working on the occasional top balance at 56.8V, there seems to be a problem there, apparently there is a maximum voltage of the pack that the Neey accepts.
- connect the Neey to the pack again (first cable harness 2 (cells 9 to 16) and only then cable harness 1 (- pole + cell 1 to 8), the Neey will then start up
- connect to the app (Enerkey) and look at the settings.
Since I did this, no more errors. I have asked the supplier for specifications of the Neey regarding max pack voltage etc because I still want to be able to do a top balance (occasionally) at 56.8V.
Good luck, Bart
That's a shame, I hope it continues to work for me now.That weird, my charging voltage is only 55.2V (16cells). The only way to get it working is to let it NEEY unconnected for few days as if waiting for the supercapacitor charge to run out. Yet, the same beeping issue still happen after few days of usage.
I bought another 10A balancer from other supplier (Enerkey) and there is no issue after continuous usage from February 2024 until now.
For experiment sake for the problematic Neey 10A, last week I plugged it into my new BatteroTech pack and guess what, after running well for 4 days, it beeping again....sigh.......
Yes, tried with Growatt SPF5000ES (Sinopoly) and SPF6000ES (Batterotech).That's a shame, I hope it continues to work for me now.
I have also noticed that sometimes the Neey seems to 'reset' and sometimes not, it seems like errors in the boot process remain cached.
I also made an intermediate step once by first connecting 1 harness and configuring an 8P battery, then the Neey started up. I also worked for a while with 'only' 5A level instead of 10A. Against all knowledge
It's just really bad that it works so unreliably for something that just needs to run stable. I also had the plan to buy another brand, but I'm a bit afraid that this is 1 manufacturer that supplies them white-labeled to all parties.
Without doubting you Are you sure that the pack is actually at 55.2V and a charger not accidentally charges it to a higher voltage?
