Help choosing the right converter/charger?
Hi My TT has a Parallax 7345 converter. For the past year I have been using 550 watts of Solar and a MPPT controller charging my batteries. We have a 12V system at the moment. And I am using (4) 6V...

The two batteries that you removed to improve you charging, should be checked with a battery hydrometer to check the charge, also a volt meter. Because you may have a bad cell in one of your batteries.
Also, ideally you will be charging batteries that are in nearly identical condition and state of charge if connected together in series or parallel. This way they are all brought to the same level of charge at the end of the charge cycle. That is why it is recommended to use only similar battery types and of the same age. So before reconnecting them all back together again, you can charge them individually to full charge, then check they are all at the same voltage with both the volt meter and electrolysis float. Add DI water if need after the full charge not before due to the expansion of the electrolyte. Then reconnect them for use as a set.
Another point often over looked is the method of connection to the inverter and charger. It's best to drain and recharge the batteries evenly, so the positive and negative connections should be made at opposite ends of you battery banks. That way you are treating the battery bank as one large battery, during discharge and recharge, and allowing the charge/recharge cycles to be performed evenly through the entire bank.
Following proper even charge an discharge connections and cycles, even during the long storage periods, and periodic refill of flooded battery with DI water, you will get the full life from your batteries.
