14S BMS for DIY model 3 cell power wall

[Tommy L]

First Post..... But I've built lots of Electric propulsion vehicles, so I'm no stranger to Lithium
and the different chemistries. I just never used BMS's before as I was always the BMS
on my vehicles watching at the Cell Level during use. A home based system for backup and off
grid whenever possible/sun permitting is what I'm doing. I'm trying to run 60% or more of my
homes load with a MPP Solar 48v 5kw 240 split

I'm searching for the best 14S BMS with Bluetooth for NCA Model 3 cells.
I just purchased 1000 3.7v nominal model 3 cells. I'll probably build
280 cell modules with a BMS on each 48v 100ah, three all together
for a 48v 300ah (nearly 15kw)or two all together 48v 200ah (nearly 10kw) system
So I'll need a really good 14S BMS.

What are todays choices?

Thank you!

No bluetooth, but it's a "don't eff around" BMS

Zero Emission Vehicles Australia

Not a lot of 3.7V users here. Vast majority are LFP with many BMS options only supporting LFP.

https://www.batrium.com/ is another option

I got a deal on Tesla cells. I’ve been a LiFePO4 guy for years.

Thank you so much! I’ll check to see how many AH is can handle. ???

Hi Tommy, I just bought 100 cells and am aiming toward making 12v 50ah bricks to build on. Any chance you could share some info on your project? cliffrodriguez@gmail.com

Are you soldering wires on each cell to help with over charge or other cell failures if the amps get too high? I see people doing that (which tesla does) and people also directly connecting them to nickle plates.

Thanks...Cliff

Never built one before, you may want to check other resources.
