bet he already has two 12v inverters.I would think two 24V battery banks would be better for that kind of use.

The screws are fine if you add one or two washers. I bought a bunch of #14 Brass washers at Home Depot for mine.My TEMCo cable lugs are thick enough to not need the washers, but I use one anyways. A washer takes the torque off the BMS ring terminals, when you tighten the screws. I was taught to always use a washer when assembling things using screws or bolts. I cringe when I see someone assembling something without them.Why ask Amy to send out double busbars and screws if no one uses them? I thought the screws were ok with the double busbars, with the additional BMS connections and a lock washer? I'm a newbie, so I just want it done right and hopefully never need to touch it again.
If you're going to have multiple inverters, wouldn't a smaller 600W/1kW one be more efficient for the small idlling load? Then have the big ones to switch in for the larger loads.Most usage I have personally slammed at the battery/inverter setup is about 170amps on each inverter. that was 1 ac per inverter and other normal things like a tv. My trailer idles around 170watts total draw, with a router, hotspot, and blink cameras.

I'm going to make my own build thread so we don't clutter this up. Thanks for the few guys that are helping. I hope to gain some more DIY bms knowledge soon so i can ditch the valance setup.
1/2" copper pipe flattened.If you look at that pic, you can clearly see two layers of material.Too bad they don't offer those when buying, but everyone can't do everything. Do those Caleb style busbars come in length? You cut and drill the holes after determining how long you want them? Peel back the rubber over the ends and drill, right? Probably not worth buying unless you plan to use a few feet at least, no?
I was told by Amy that the current rating on the busbars is 300A. I have not verified so take it as one data point.How much current can those carry when doubled up?
For 16 batteries. She quoted me 338 for shipping by sea to California.
To be clear, $338 for shipping. Plus the cost of the batteries. I'm hoping that's DDP but I'm not 100% certain yet.
