And then I found this.. https://signaturesolar.com/eg4-lifepower4-lithium-battery-12v-400ah/ Kinda makes it hard to spend the time and money building a battery when I have a shunt already. Wow.

Hi, i'm looking for opinions more than help based on others experience as I read the forums and educate. I am looking to swap out my 2 Lion Energy batteries for 600ah of DIY Lithium. I currently have a Victron Multi Plus, Cerbo GX, Victron Solar and Victron Shunt. I'd like to use the Victron...

I've learned that pretty quick lol. So I guess looking for a BMS compatible with the Cerbo. One solution i've found is the 302 AH Battero Cells, so potentially 2 of those battery banks Potentially a REC BMS?

i'll stick to 12V for this project, so 600ah is as large as I want to go. The larger project is for my data center and i'll do 48V for that one. but doing this as a proof of concept and to get a solid understanding of all of this. For my RV, I have shore power, but my goal is to run it entirely...

I also wish I had the 24v victron, but that came out just after I got mine, and I didn't quite understand how beneficial 24V would have been. I would have just used one of my lion batteries for my 12v side and ran 600ah for my 24side...oh well!

I’m trying 13.9 bulk and 13.7 float and it seems to be stable now

I’ve been having issues with mine... charging from a go power ic3000 I keep getting over voltage errors... according to go power the mossfets aren’t big enough? they bulk charge ok but I had to turn down my float voltage. So I can’t get them to charge to 14.6 only about 13.6. Kinda disappointing.
