Battery Booster replaces battery in RV Circuitry?

...I will start rewiring completely my F.G camper soon. My planned circuitry consists of all components like all RVs, such as shore power 120VAC comes in, it also branches to converter and the camper will have lights, accessories for both sources of 120VAC and 12VDC. (The converter will have one lead to feed to battery for charging when battery is low, as normally). Here is the issue: I didn't buy a battery yet, but one friend of mine gave me his old battery booster. I think about using this battery booster as of...battery in the trailer. This piece of battery booster alone can supply 12VDC for a few lightbulbs for 2 days( I tried) and will be charged from household 120VAC adapter, as it is designed to do so. Now, if I put the battery booster in as it is a battery in my camper, how does that affect to the circuitry ? Please share your thoughts and if anyone had ever done it, please let me know. Thankyou...

By "battery booster", do you mean a portable booster pack, such as a Xantrex Powerpack? That would work without circuit design changes; it's just a small AGM battery in a carrying case, usually with some accessories such as booster cables. Depending on the pack, it could be annoying to make the connections - it might be easier to take the battery out of the pack and just use it by itself.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

I've always associated "battery booster" with a jump starting pack; a small starting battery and recharger. If that's what you have, then capacity and lifetime might be less than desirable. Let us know how it goes. Raz

Why? A used battery booster is just that.
The batteries in them have a shelf life also.
You would be better off using a led lantern.
Replacement batteries are still $35.00 for those boosters.
Just replaced mine.
