I see from your picture that you did provide heavier cables for the battery to rest of system, so you did recognize the need for higher current capacity there. I suspect you are not measuring equivalent current on negative and positive sides. How are you measuring current? You would need to...

Remember that the cables going to the inverter needs to carry twice as much current as the cables between the batteries. If your intent is to add more batteries in the future do not continue to connect in this manner. Instead use a star configuration with all positive battery terminals connected...

You won’t be able to hook it up with your van battery. Different chemistries mean different charging profiles and different charge levels. The stock alternator won’t be up to charging the LiFePo4 either. Consider a second beefier alternator designed for charging this type of battery. As for the...

Here's the link to the video you are referring to. Note Will mentions this might be an issue if you have three or more batteries in parallel, which it sounds like you are not. His main concern seems to be about one of the batteries going bad which can affect the other batteries. He mentions that...

Which video?

To clarify and correct something I said that might be misleading. If you compare like kWh capacities then serial and parallel can charge at the same speed. Two serial batteries at 12v 200 Ah, are the equivalent of two parallel batteries at 24v 100Ah. Both have a .2C rate of 40A. The parallel...

Here is my thinking on that question. Two batteries in series can get out of balance with each other, just as the series cells within each battery would get out of balance if not for a BMS. If one of the batteries should die for some reason, you no longer have 24volts. With two batteries there...

Not sure how deep those studs go in. Maybe drill and tap them?

Just received two of the Lynac 25.6 (nominal 24) volt 100 Ah batteries. Note that these are actually rated 120 Ah but Lynac recommends only 80% discharge so market them at the lower capacity. Price was $1482 Cdn each, after 10% discount. Even though each of these weigh 50 lbs each there was no...

Buy them some nice jewelry first. ?

A quick , LATE, question. Why not configure these as 2P8S? Then you would only require 1 BMS, albeit one capable of a bit more oomph in the balancing.

Typically made from tempered glass. If you are comfortable parking your car under the trees then your panels should be fine.

As long as you don't run them on the same circuits. So, you need to isolate your wiring so each has their own hot, neutral and ground. Outlets would then be connected to one or the other.

Drill, tap and short bolts?

MidNite has one for the panels. It connects in at the combiner box. Basically, it will route surges on the positive or negative solar line to ground.
