You got the battery on the TT or at home on the charger? Why not plug the TT in? It will get charged and maintained. It doesn't hurt to get more educated on electrical setups.
Doing the wrong thing can destroy things but also lives and can be very costly. Batteries can explode doing the wrong thing. With charging Hydro gasses get released and all it needs is a spark. There are books available to learn more about all the accessories in the RV world. Good luck with your TT.
