Rookie here. Presently researching batteries for battery bank. Local big box stores sell deep cycle batteries which i have used many years for trolling motors. I have always been impressed with the capacity of the batteries. These are flooded lead acid which seem the best value given I don't have an unlimited budget for this.
This installation is for back up power only so barring the end of civilization I am not expecting frequent charge/discharge cycles.
Wondering the difference in construction and/or chemistry that takes the "official" battery bank batteries 60 - 100% more expensive for a given capacity rating than the bog box store "marine deep cycle".
thanks to anyone taking the time to educate a rookie.

ps. if there is a good book that details the considerations for a charging system and battery bank I'd appreciate a reference. I am an engineer so it can be technical in depth. (Most of the stuff I find googling is very elementary.)
