I have 4 100ah lifepo4 batteries connected in series parallel to make a 24v system but i noticed from the bluetooth bms that sometimes they are 1 or 2% difference in the Soc but the voltage are within 20mv of each other. As i have a battety balancer connected. Is this 2% difference bad or...

Current configuration. Including balancer and bluetooth battery monitor.

I dont have any victron product currently and there is still the fact that the victron costs more than double the cost of the TBD.

Does anyone have experience with the TBD smart shunt? Is it as good as the victron smart shunt or not good?

Thanks. did some research just now and realised .

The white wire with the black tape is the negative charge coltroller wire. You are saying that that white wire needs to also be at the front of the shunt?

The negative wire from the charge controller is connected to the battery on the same terminal as the shunt..

I bought a battery monitor as seen in the attached picture. I think the configuration is correct but for some reason the AH keeps going up ad it charges its as if its reading amp hours coming in from the charge controller. As my battery back is 200ah at 24v but ah on the shunt is now showing...

I already have the balancer connected and since i have them i havent gone under 75% from over night use . I will be adding more loads tho.

Because of them being at different SOC at times?

If the manufacturer states that a battery can use 4 in series or 4 in parallel. Would putting them in 2s3p be allowed or thats too much for the bms?

Yea i will be changing to 6mm² before i go 2s2p.

I will be expanding to a 2s2p array eventually.

That being said. I now have 2.5mm² wire running from my panels to charge controller. Would it be good to change from the 2.5 to 6mm²?

Yea this is the reasoning i had in mind y i kept wondering why the amprage went up that high. Thanks for vlearing this up for me.
