The Concept of Maximum Charging Voltage for 12 Volt Lead Acid Batteries. The maximum charging voltage for a 12-volt lead-acid battery typically ranges between 14.4 to 14.7 volts. This higher voltage is necessary to compensate for the inherent inefficiencies in the charging process and to ensure that the battery reaches its total capacity.
Normal lead acid batteries are not happy with charging or discharging at more than 20% their C rating. Your batt bank is rated at 230Ah x 2 = 460Ah @ 12v. Your max realistic charge rate for your battery bank would be 20% of 460a = 92a.
The inverter draws about 3.5A - 4A at 12V, tested on a large power supply. The current range I have supplied is through a Pb battery''s discharge curve, from 12.5V to 10.5V. I have looked at purchasing a small 4Ah 12V Pb battery, but I am hesitant, because I am unsure of what currents the battery may be able to supply.
$begingroup$ Drawing lots of current from a lead Acid battery will simply make it hot as mkeith mentioned, it may in some circumstances melt the terminals or part of the internal connections. The internal heat may also boil the acid electrolyte so you may have boiling acid spray, but given how much energy it takes to boil water (which …

There is no such thing as a "maximum current" for a cell (the way there is for a fuse, for example). If you read that a cell has a "maximum current of 1 A" it doesn''t mean that it''s perfectly fine at 0.99 A and that at 1.01 A it''s destroyed.
Considering the charging current of the lead acid battery it should be half or less than the maximum current rating of the battery. In this circuit, LM317 IC is used as constant voltage source of 14.4 V as the 12V battery used in the circuit has a peak terminal voltage of 14.4 V.
