Industry Does battery voltage change based on voltage supplied to charge
If the charging voltage is too low then the battery won''t fully charge and so the resulting battery voltage will be (slightly) lower than if the battery had been fully charged. In general the charge voltage mostly drives the charging rate, with the caveat that you should always have a charging current limit to prevent overheating.

Applying Kirchhoff''s current law, you can check it for yourselves. No matter your circuit and its operating conditions, the current going out of the battery should be equal to the current going in. The voltage only changes because the chemicals inside the cell are changed slightly and not because of a change in the number of electrons.

Industry How can something have high current but low voltage, or high voltage
If you want to minimize losses in the transmission line, you use a transformer to change the output voltage to 10000 V for example, and therefore the current would decrease proportionally to 0.1 A, since a transformer outputs (ideally) the same power it gets at the input. So stepping up to high voltage/low current is incredibly useful for
Industry Circuit to shut off inverter at low battery voltage set point = 50%
Some inverters have a "Low Battery Disconnect" in them, but they are set too low usually. I think you could use a 12V relay, and a trim pot in series with it, to control the 115V output, adjust the trimpot so the relay just drops out at your desired voltage, and have a "override" push button switch to short out the trimpot, to reset the relay.

One way to increase current flow in a DC circuit while keeping the voltage constant is by using a transistor. By connecting the output to the base of an NPN transistor, you can amplify a low current voltage signal to a higher current without changing the voltage. Can capacitors be utilized to boost the amperage in a direct current setup?
Industry Adjusting charger''s voltage
Once the charging current is down to around 100mA at the target voltage, the battery is fully charged and the charger shuts off. If you change the target voltage then this process will occur at that voltage (whether lower or higher). But the balancing process is in the BMS and not the charger so it won''t directly impede the balancing process.
Industry How to Lower Amperage
If the voltage is too high, it can cause the circuit to draw more current than necessary, resulting in higher amperage. Another adjustment you can make is to adjust the current limit of the power supply. Most power supplies have a current limit setting that allows you to adjust the maximum amount of current that can flow through the circuit.
