A basic BMS will monitor the cell voltages, conduct protection functions against over-voltage, high current, high temperature, and provide passive balancing. The second generation of BMSs is modular rather than centralized and can actively balance the battery pack based on cell-to-cell-level measurements, which allow a higher degree of control and protection.
BatteryStuff Articles | The Lead Acid Battery Explained
The level of charge current that can be applied without overheating the battery or breaking down the electrolyte into hydrogen and oxygen is known as the battery''s "natural absorption rate." When charge current is in excess of this natural absorption rate, overcharging occurs. The battery may overheat, and the electrolyte will bubble.

Why do high current conductors heat up a lot more than high …
Remember, current is defined as the amount of charge passing a given spot per unit of time. It makes sense then that the more charge passing a spot, the more collisions occur and therefor the more heat is dissipated. This is why power lines use high voltages for transmission so that they can provide more power with less current.

power supply
To absolutely maximize solenoid current without regard for battery life, set ratio of battery time to "shorting time" so that the battery is drawn down to about 4.5 volts. That will draw maximum power out of the battery, even though it will cause the battery to waste about half of its energy heating itself.
