To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
However, the amount of current we can really draw (the power capability) from a battery is often limited. For example, a coin cell that is rated for 1 Ah can't actually provide 1 Amp of current for an hour, in fact it cant even provide 0.1 Amp without overextending itself.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
Normally for boost converters the maximum output current is determined by the switcher chips maximum current rating and the voltage boost needed. So for 3.7 to 9 v you are boosting by 2.5 times so at a current draw of 400 ma the switcher chip will be switching around 1 amp which should be OK.
Voltage * Amps * hours = Wh. Since voltage is pretty much fixed for a battery type due to its internal chemistry (alkaline, lithium, lead acid, etc), often only the Amps*hour measurement is printed on the side, expressed in Ah or mAh (1000mAh = 1Ah). To get Wh, multiply the Ah by the nominal voltage.
To obtain a charging current of 100mA, a resistor (R) of twelve ohms may be used, whereas for a current of one amp, a 1.2 ohm 2-watt resistor is required. A diode can be added in series with the input to prevent any reverse voltage from the battery packs to the regulator IC when power is turned off, and the batteries remain connected.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh ). A Watt-hour is the voltage (V) that the battery …
Batteries output power when they are connected to a circuit. A battery that is not connected to a circuit provides no current and therefore outputs no power. However, once you …
$begingroup$ So in other words, as the cell in the parallel bank approaches total charge depletion, it would not affect the bank V when it is 100% depleted,but it would …
Rectifier diodes: These diodes are responsible for converting the alternating current (AC) output of the alternator into direct current (DC) that can be used to charge the battery and power the …
Therefore, though we get 120VAC as output, we get 10 times less the current. So if the battery is rated for 30A, the maximum current that we will get out is 3A. Again, a 12V 30A battery can …
This guide will walk you through creating different constant-current battery charger circuits, giving you the power to revive your exhausted batteries and keep them charged for extended periods. No matter how tech …

How can i calculate the maximum current a battery can provide if the only information i have is: 7.2 V / 11.5 Wh / 1600 mAh. I know that if i can multiply C rate with Ah i …
To ensure that your 12V battery can handle the increased current required by a boost converter, you need to check the battery''s current rating and capacity. The current rating, typically expressed in amperes (A), …
To extract higher amperage from a battery, you can use a battery charger or conditioner to optimize the charging process. You can also use a battery isolator or combiner …
The DC-DC will only output the current required to maintain 3.3v and nothing more. If your load is 100mA then only 100mA will be sourced from the battery regardless of …
In our example, the 6 volt battery would hit this point first, but the 12 volt battery is keeping the circuit alive and would start attempting to recharge the smaller battery. By forcing …
