Good luck - I am sure you will do well!

I don't want to appear to be condescending but I would encourage anyone who is putting together a 12v high amp (read lithium) system to fully, and I do mean to every detail, understand what each of the components can do, and what they can't do. These systems can have plenty of power enough to cause fires or other serious issues. When I read about "I didn't know that" things it does give me pause and concern.

For instance, you need to look at how the particular b to b charger works to determine if you need a separator or not on a single alternator system. If the b to b won't activate without the engine running, you don't need a separator, and if you want manual control of "off" on the b to b you just do it with a switch to activation power to the b to b which is usually off the ignition "run" position. If you use as separator only, you won't be able to manually shut off the charging unless you add another switch to control the separator. You don't want to just shut off the charging output of the B to B to the batteries as that can cause damage to components in some cases.

Please don't install a system until you positively understand how it works, if you do it yourself.

Valid point, the potential unintended consequences of wrong design and wrong implementation could be serious. Many years ago, I purchased a 21.5’ Bigfoot trailer. I asked the dealer to add more batteries in the trailer tongue storage next to the LPG tanks. Fortunately, I noticed smoke before likely fire of cables insulation near LPG hoses. Battery lugs were “crimped” with chisel and hammer covered with insulation tape. Crimping was so bad that cables were hold in place by the insulation tape, not by crimping. So, attention to every detail is critical.

I have multiple types of crimping tools, from hydraulic for battery lugs to hand tools and all of my wire terminals use with heat shrinkable tubing.
