A really simple way to charge a battery is to use a buck converter, you need to have a diode on them but you put the solar in, dial in the voltage and current and away you go.
I recently got some "charge controllers" where you set the voltage and cut off and it protects the battery regardless of type. one is a LV ( which is the DC voltage) and the other is HV (main grid) controllers which will cut or turn on charging.
This is great if you have winter solar battery issues and need to have a "emergency charge" put into place.
