Free QuoteA battery''s voltage naturally drops as it discharges. To get a stable voltage out of it, you want a voltage regulator. Voltage regulators come in two flavors, linear and switching. If you want the output voltage of the regulator to ever be higher than the battery voltage, you need a switching regulator. You''ll also get higher efficiency that

You should take the starter motor power (usually 1-1,5 kW, that is still overestimated, if you consider the drop in battery voltage) and the time to start the car.

Free QuoteIn series connections, maintaining balanced voltages across all batteries is important to prevent overcharging or undercharging. In parallel connections, equalizing currents among the batteries is necessary to prevent imbalances and avoid premature failure of individual batteries. Importance of Proper Battery Maintenance and Monitoring
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that's what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
When batteries are connected in parallel, the voltage across each battery remains the same. For instance, if two 6-volt batteries are connected in parallel, the total voltage across the batteries would still be 6 volts. Effects of Parallel Connections on Current
Rechargeable batteries (like the kind in your cellphone or in your car) are designed so that electrical energy from an outside source (the charger that you plug into the wall or the dynamo in your car) can be applied to the chemical system, and reverse its operation, restoring the battery's charge.
“A battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity,” says Antoine Allanore, a postdoctoral associate at MIT's Department of Materials Science and Engineering.
