Choosing a new house battery

Just so you all know what is going on. I ordered a new charger/controller. The unit I ordered will be able to service Std, AGM and LiPO4 batteries by switching modes. This way, I can observe the unit with my current battery, and if necessary then get another battery later. In the event there is anyone else that is thinking of changing over at a later date, one must be sure that the LI battery is charged before use. So, you would have to have a LI charger prior to hooking it up to the RV. The unit I am getting is from Progressive Dynamics and is not on the open market, but is available only through the company. The model, in case anyone wants to look it up on their web site is PD9300.
