I am sure this is not how to use Twisted Pair cables. You should use only 1 pair, and use Pure Copper (not Copper Coated Aluminum) as it needs to conduct as much as 1A. Better result is to use Shielded Twisted Pair: each pair is shielded Best result is to use Double Shielded Twisted Pair...

I visited my brother in law in the big city (Manila); he lives in a mix Industrial, Commercial and Residential neighborhood were 3Phase Y or Delta (3 Transformers) coexists with 3Phase High Leg (2 Transformers). I traced the posts and wires and both groups of transformers share the same High...

Me too. And not just Balancers, but also the BMS. Inverters are getting higher and higher power, HV batteries (>90v) are gaining traction.

That is prohibitively expensive! Almost at cost of commercial HV battery packs!

On your photo, are you trying to make a high voltage battery pack using small BMS in series?

How much?

1S bms that can be strung together for form higher voltage.

I have long abandoned SOC as well. Simply put, you cannot count electrons and expect all electrons are accounted for. Just imagine: if your BMS has an accuracy of 99.99% or 0.01% error. In 1 hour time it has accumulated 0.01% error; in 24 hours 0.24% error. How much error do you think it...

There is timer when it reaches Undervoltage? Where is this variable? Attached are my current settings and system logs. I changed my over temperature to 40 yesterday; will bring it down to 39C once I fix the cooling.

oh.. didnot know. i was out of the loop for a few months..

Deye has logic built in circuit/logic to limit the power draw out of their MPPT.

This Morning, my Deye shutdown (due to low battery) and I went to investigate the cause. My Deye is configured with Shutdown Voltage of 49.5V or an average cell voltage of 3.010V. My 16s JK is configured UVP of 2.800V and far lower than the 3.01V. However, it is possible one of the cells went...
