Lead-acid batteries: Generally speaking, lead-acid batteries have a lower operating voltage range. The charging voltage of 12V lead-acid batteries is usually around 13.8V - 14.4V (for ordinary 12V lead-acid batteries). For deep-cycle lead-acid batteries, the charging voltage will be slightly higher.

Lead-acid batteries don''t like being overcharged. In general, they''re charged with a 3-stage charging process: a constant-current phase, driving as much current as is available from the charger, or that the batteries can take, whichever is less; then a constant-voltage "topping" charge which is nominally 2.3V per cell, but if you''re fancy it varies by battery

I don''t see why not, as long as the batteries can handle the worst case charging conditions (both charge controllers delivering maximum current simultaneously). MPPT charge controllers (and lead acid battery chargers in general) basically act as current sources for the bulk of the charging process, so paralleling them shouldn''t have ill effects.
In authors proposed plug-in module, consisting of lithium-ion battery and supercapacitor, that is connected to the lead–acid battery energy storage via bidirectional DC/DC converters. The aim of the module is to reduce current stress of lead–acid battery, and as a result to enhance its lifetime.
The combination of these two types of batteries into a hybrid storage leads to a significant reduction of phenomena unfavorable for lead–acid battery and lower the cost of the storage compared to lithium-ion batteries.

The developed controller can maintain the output voltage under load variation from no load to sudden load of 0.26 A.

Lead–acid batteries are popular mainly because of low cost and high reliability , what makes them attractive, especially in the developing countries. However, they feature short life-cycle and are not resistant to conditions that may appear in PV systems like undercharging, low state of charge (SoC), high charging current .
Thus, more popular approach is use of power electronic converter between batteries, that allows for current control. In authors proposed plug-in module, consisting of lithium-ion battery and supercapacitor, that is connected to the lead–acid battery energy storage via bidirectional DC/DC converters.
