Time for Lithium House

[Barking Sands]

I had issues with the Orion today. At some point, I blew the 60a MRBF on the output side. The Orion worked great before, but not at all today so the fuse was blown before I started. Idiot that I am, I don’t have a spare, and since I don’t know why or when it blew I’m not going to put a 300a fuse that I have on it. So that is still something to work out.

just checked the manual..says 60-70. I guess 70 it is.

None of us, including yours truly, are immune from being cheap when the downside is known, mitigated, and limited.

I would have likely done the same thing and made sure that the terminal squeeze was done right. Nothing wrong with 95mm2 conductors, just unusual, that is why I asked.

Take the $200 that was saved and enjoy a fine dinner with those that you love. Great job!

WRT the blown 60 Amp fuse, at this level of current I seldom use a fuse. You can get a Blue Seas 187 series (Edit) 70 A CB on Amazon for about $80. Or about a third of that price for a knock off, which I have never used.
Provided it is downstream from a class T fuse you are fine with the Blue Seas (really a Bussmann) product.

Yeah, I will replace with a 70a if I can.

Edit: MRBFs aren’t available in 70a. They are in 75a, so I’ll go with that.

I would use a CB other than space is really at a premium. The MRBF is convenient. Except of course when it blows. Lol

Repeat after me. Lithium Iron Phosphate batteries (which are the kind used as house batteries in a boat) are not the same lithium batteries you find in a cell phone, power tools, etc. LFP doesn't have the same concerns around thermal runaway, etc.

How about Mercedes? They don't know what they are doing?

What type of chemistry did they use?

This is ignorant fear mongering. The automotive industry does not use LifePo4. The chemistry does not work for their power needs.
