In a vehicle mounted system? From what I read in this forum and sailing forums. Tldr: Class T is currently recommended for subdivided LiFePO4, under ABYC TE-13, will become a requirement when TE-13 becomes a full blown standard. Subdivided means the individual batteries each get a fuse so as...

I decided to go with class T fuse for each battery. Here is the latest diagram revision.

Was it from this article http://pe.org.pl/articles/2017/5/13.pdf ? Discovered in https://diysolarforum.com/threads/lifepo4-prismatic-cell-short-circuit-current-and-main-circuit-protection.14343/

From what I remember from my research back then, aren't MRBF less suited for lifepo4 batteries because of a lesser AIC / Interrupt Capacity ?

Making progress on the V2.

I took only these 2 models as examples because I couldn't figure out their amps rating based on their cross section.

Yes, that's the same I "measured" on the cad model. And later found out in the specs ^^ I compared two high power busbars. https://www.victronenergy.com/dc-distribution-systems/lynx-distributor https://www.bluesea.com/products/2104/PowerBar_600A_BusBar_-_Four_3_8in-16_Studs But when I...

For the POS battery busbar, I was thinking of something similar to this in concept. When I looked at the lynx distributor, each busbar is 8mm by 30mm but they are rated for up to 1000A. But when I look at online calculator for busbar ampacity, this width and height results in 288A max. For my...

Nice! I had seen a few of these on the forum. It looks like a DSL (Domain Specific Langage). https://github.com/jgraph/drawio I saw that library when I did my initial research for this project.

Sorry for quite the long silence. I haven't given up on this project but some others got in the way. I've only seen mentions of it. The simulation would probably come at a later time but would indeed be nice! At the time of my research last year, these were among the best diagrams in terms of...

I understand your logic. Last year when I did my first. I documented my journey here. https://diysolarforum.com/threads/van-12v-14kwh-lifepo4-help-needed-for-diagram-review.15070/ Wasn't getting any answers so I thought about doing an electrical oriented, simpler to follow topic.

It's Lishen 272AH cells. 150A JBD BMS. What exactly is a discrete fuse? That's my current install. I was a bit in a rush last summer. So I did a v1 with only 1 pack. But I would like to use the AC inverter for bigger load and putting 4 packs in this space seemed complicated so went with 3...

@smoothJoey: what do you think about fusing each battery pack with it's own class T fuse and another additional 400A class T before the Lynx distributor?

After two many diagrams and pdf I probably looked at the wrong one indeed. At the same time, they show a Multiplus diagram on the Multiplus2 product page...

I'm not sure. On online pictures of my model, I see 1 stud positive, 1 stud negative. But in the 230v manual, I see stated that there is 2 studs postitive and 2 studs negative.
