The real engineering answer for why you can't get a good easy to understand answer. " IT DEPENDS " my friends know it is gonna be a long day when I start the explanation that way....

TBH you'd have a hard time losing the packs we had, you could just about lift one pack at a time, built in on/off key so the pack is off until everything connected and ready and if some dumbass has co

I have a Ramsey worm gear winch rated at max 280 amp draw
Winch originally came with #4 awg cable
Charts say #4 cable good for 100 amps at 9.4 feet
I am installing Anderson power pole SB175 quick connectors to be used with the winch and homemade #1 awg jumper cables. (Passenger battery with connector by the grill at the bumper)
Chart says #1 cable good to 200 amps
SB175 good for 175 continuous amps according to Anderson.
Largest size cable compatible with SB175 is 1/0…but charts say 1/0 good for 300 amps at 8 ft…this is well beyond the 175 amp rating.
So I’ve got a winch that will draw 280 amps that came factory with #4 cable which is only rated for 100 amps. A 175A connector that is compatible with 1/0 gauge cable that is rated up to 300 amps. I have #1 awg cable good to 200 amps. This is why people go rogue…more disinformation than the CCP virus. None of it adds up. I guess this 12vdc stuff is more of an art than a science.
Now, I’m guessing the whole “continuous draw” thing is the key here, and Anderson does say the SB175 can handle higher loads, but that’s pretty vague. (How much higher and for how long?)
They do make a larger SB350, but most of the accessories I see myself using with the quick connectors are smaller and wouldn’t be compatible with the larger SB350 housing/contacts (winch with #2 cable, #1 jumper cables, inverter, etc)
Anybody using the quick connects like this? Tips and best practices appreciated.
