I have never had a conversation about batteries with anyone who "claims" to know all about them and not come away with LESS knowledge and understanding than before I asked my questions. It always ends up where I am suddenly Penny talking to Sheldon about quantum physics (which I do understand, oddly). All I want to know is, without all the scientific electrical laws and zap-code wizardry, which battery would suit my needs, either a deep cycle or a 12 v? I have always used a deep cycle for my builds, simply for the fact that I stated above... I cannot get a simple clear answer. Anyone who sells batteries wants to upsell, so I don't trust them. Anyone who sells car parts and batteries wants to sell what has been sitting on the shelf forever. A deep cycle always had plenty of power for what I need, which is powering an inverter (1500) to run LED lights, a pencil sharpener, and a radio. Not using power tools or a heater or huffing the engines on a B-17 bomber. I may or may not add solar but since my trips are usually a day or three at most so I don't need apocalyptic boon docking endless power, usually just a day any the lake kayaking or day hiking trips, and hanging out at the park for events. In my school bus conversion I had a deep cycle, also in my horse trailer conversion, but never ran the battery dry of power.
So I ask, is a deep cycle overkill (I believe it is), as well as not being as efficient as say a 12v or 2 6v? I don't need cca's, just smooth easy power from my inverter. I have no problem hooking my charger in between trips.
I know the simple answer is "if it works don't fix it"... I agree, but if I don't need a steam shovel to dig holes to plant petunias I would like to avoid it this time.
Thanks!
