I'm planning on building a building a 304ah (or 280ah) batty for my RV and I'm looking for a little advice. I've figured that I use about 50ah a day, I haven't measured this with a shunt, but only based on a two day trip where a drop in 100ah battery barely made it (based on measuring voltage) and I would like to be able to do a 4 day trip with room to spare. I would like cold temp protection as my batteries sit on my trailer tongue and I just don't want to worry about having issues. I will only be using the battery for running my RV's 12v systems and I do not plan on using an inverter. And I would really only be relying on the battery a few times a year in the spring and fall as otherwise in the summer we typically have electric sites as it gets too hot here.
The building a battery seems like a no brainer to me as I can get a set of 304ah cells for $500.
One of the things I am stuck on is which BMS to use and would like recommendations. I don't need high amp capacity. Bluetooth would be nice, but I don't think it is necessary. I want a quality unit that I won't have worry about failing. I've ready great reviews about the Overkill BMS, but at $140 I was looking for a cheaper option if there is a good option.
Lastly, I figure I will have to make my own "battery" box and I was curious if anyone had examples that they have done.
