@starchy - hey OP, what did you end up doing?

Oh, no! Not at all - I was talking about Fred giving me that advice via email. He's the one who said if it doesn't get hot it's good. I found that odd.

Thanks for the reply. I see you went with the SB350 connectors. Nice choice.

? ?

"Fred" from battery evo tells me that this product is 175a max, but the product page lists 350a. Waiting on a reply from Fred, but wanted to post this here. I asked him if I could run 175a "continuous" from the 12v 120ah product - which I still cannot figure out.

My use case would limit me to like 5 minutes max of 175a draw. I feel like 1/0 should be fine if it's a short length, but I want to do it right.

I'm going to try it with one and see what happens. Don't worry I will fuse everything and monitor it closely. :D

Hi there, when you say "final pack cable" are you referring to the cables on the inside of the box or just the last run to the anderson plug on the outside? I've in the exact same boat as OP except one big difference is I only have 1 12v battery-evo (big battery) pack, so nothing to split the...

hey op, i've got the same or a very similar battery setup to you. Mine is the batteryevo 12v 120ah with same BMS, fuse, etc. Do you have a schematic or can you describe your system? I am trying to figure out what connectors/wire sizes to use coming out of the sb175 to my busbar and on to 2500w...

Yeah, I think i'm just getting hung up on the nomenclature being so new and all. I heard back from the vendor again and his reponse was basically just to try what i want and see what happens! If the wires don't get too hot then i'm good type of thing... which doesn't exactly give me great comfort.

Odd to get that sort of advice from a vendor methinks! Fred is the vendor, the guy in the email above.

Does it matter that the wire inside the battery running to the sb175 connector is 4awg? How is that supposed to handle 175a continuous?

I've got a few appliances that will pull 1600w from my inverter + my dc fridge + other 12v loads. If the appliance needs to run for 3-4 minutes that's 175a continuous.

I hear you and completely agree. I would only be running it near that max for 2-3 minutes at a time, once or twice per camping day (not many times yearly). Really I just need to know if I can safely go from the anderson plug on the battery to a busbar to inverter and pull 175a at the intervals...

Can I see your chart? I was using a Blue Seas one.

Gotcha, that makes sense, and something I hadn't considered. The problem with that is that the connector is built into the battery box and there isn't room for another. My other option is to buy the beefier anderson plug that is the same size, but takes 2/0 and is capable if higher power. I'm...

I am in the same boat as OP, but can someone help me understand why the sb175 connector is rated at 175a if the largest gauge wire it can accept (1/0) is only rated at 150a? Can I safely run 1/0 from the battery to a busbar at a very short distance while pulling 175a continuous? And if so what...
