Watchmon still doesn't have even a MOSFET to automatically isolate a string under a detected failure. While different BMS architectures...

Two is better than four or eight. You are at least limiting the energy that can be backed to that of a matched unit.

Hi again, If i came out rude in one of my posts, my apoligies, it has been a rough time lately. Indeed full metal shelves lined with...

Oh, sure. I was just trying to find an upper bound in this case, with a lot of assumptions of course. Having said that (and I don't...

SWAG, but anything lower than that makes them grossly inappropriate for an automobile with >100 LFP cells in it.

Agree on all points. A mosfet is really just a control device and not a protection device, the "switches" are unlikely to be able to...

If all the batteries are connected together at a Buss-Bar and then to a Fuse, It could happen that one pack shorts out and all the other...

The contributing strings should be lower on the curve, so they below after the shorted string; 7 strings really does put you at a...

Looks like only 1 of the Phases (L2) had a large draw? Am I reading that correctly?

Ideally you would fuse everything, but the SOK does have a circuit breaker that should be able to isolate the unit from the system...

The rack itself was steel and rated for 300 kg/shelf if i remember correct. There was little to no sagging. The hpl i just added as...

Guys, please, yall looking at things way too far. The shelves were fine, the fire fighters have torn everything apart to drag all the...

Yes I know he had compression, I’m suggesting the amount of compression might be an important factor. Perhaps if the cells were over...

Are you going with Batrium again? It seems more designed that perhaps you have a 16 cell config, and you decide to add another 4 cells...

Class T or any other fuse only stops current flow after some time/current curve is exceeded. A bad cell and reverse current could...

Hi all, I'm really not asking for anything, but someone asked, so here is a link of an action my friends set up...

Insufficient information to make that determination. The Mega Fuse was the second failure we can see based on the shunt data. It is...

A raspberry pi with sensors tucked in around the room and in the gear. You can do the 1-wire sensors on it and tack on as many as you...

To be fair almost all melted / burnt fuse holders are caused from poor connections, not from faulty fuses. There's a huge difference.

It really depends on your layout; in the US string inverters are often used with single axis trackers for one row. Central inverters are...
