I'm configuring a jump starting connection to the n70 series battery in the battery box of my tool trailer (which has a 110 watt solar panel and regulator keeping it charged all the time), and have been thinking about doing the exact same thing with the 80. The intention is to have both configured the same.

I have a couple of spare megafuse holders, so probably thinking of 250 or 300 amp megafuses (one for each batt + feed to an anderson connector at the batteries), 35 mm2 welding cable to convey the current, and a red anderson plug of either the 175 amp or 350 amp size.

Is anyone knowledgable on what the inrush current for starting a 1hz or 1hdt motor is? My home-made main battery cables in the 80 are 25 mm2 welding cable with crimped lugs and they cope fine, but they're short (under a metre for the batt + to starter and batt - to main motor earth) so for longer cables the next size up will do to reduce resistance.

My brain is telling me that 350 amp andersons are overkill for a landcruiser jump-start setup but I'm open to advice on this.

I'm currently deciding on a config for some new jumper cables that will suit the 80 and can also be used with my cars when required as part of this which might be anderson to anderson with custom short plug-in's if aligator clip connections are required at either end depending on the situation. I'd be using Narva # 57320 and 57322 battery clamps for this.

Further to this, I know that andersons are 'colour keyed' but have not found any sort of 'standard' for jump-starting connections/cables. I just happen to have a red sb175 connector here (came with a Witsend product) so sort of defaulting towards red. Grey is a bit boring. ;) But I do see a fair number of jumper lead products that are made with yellow Anderson connectors.

I don't know if in the wider 4wd community there is any sort of 'accepted rule of thumb' for anderson-connector based jump-starting setups. 50 amp grey anderson's are almost ubiquitous now, so most people know what they are.
 
Lithium jump start packs use connectors that are rated for 60-90 amps and they work just fine.
 
No way thankyou they are just dangerous pieces of junk IMHO. ;) Nice idea though.
 
Right, I'm saying those connectors are rated for 60-90 amps when you were wondering if a SB350 was overkill.
 
The reason to use big(ger) connectors is reduce contact resistance in as many places as possible. Obviously no aligator type battery clamps have 'optimal' contact area. That's what made me consider the 175's (apart from already having one to physically look at) as a sensible starting point. As much as the 350's seem great due to their bigger size they could simply be overkill. I know an 80's motor is bigger than a normal car engine hence the question about inrush current, but I'm sure that 175 amp andersons will deal with very brief surge current higher than their rating. Anyone with lots more industrial experience using Anderson connectors able to say anything from experience about that point?
