No worries, though! We''re diving into the ins and outs of voltage, why
$begingroup$ You cannot and should not charge a car battery this way. The voltage is too high (more than 13.8 V) so you''ll overcharge the car battery and damage it. The resistor will not limit the voltage to 14 V when the battery is full. Also explosive gasses could escape. Car battery chargers are cheap, just get one of those. $endgroup$
When charging, use a bulk charge process first to reach the target voltage quickly. After that, a float charge is used to maintain the battery without overcharging, usually around 3.4 V per cell. Avoid lead-acid chargers, as they can damage LiFePO4 batteries. There is so much about different battery voltages and how their state of charge relates to their voltage
A shunt regulator. This means using a resistor to drop the voltage like you are suggesting, but then adding an extra device in parallel with the load to control the voltage. The shunt regulator will adjust its current (within limits)

Logic = If the batteries get low and can''t produce enough of 12 volts to keep the solenoid closed then 18 volts will probably work as long as there is enough poop in the batteries to make the motor go roundie-roundie. Neat thinking huh! When my 12 volt solenoid fails - working off 12 volts I should have secured a 36 volt one by then. Or I will have broken down and bought
I'm trying to use a 48v battery on my 36v ebike controller. The controller itself can deal with the higher voltage, but it has a hardcoded limit of 44v, which it reads from a wire coming from the display. So my aim is therefore to lower this voltage somehow. The parameters are: Solutions I have researched so far: Tvs diode: used like this?
This battery pack calculator is particularly suited for those who build or repair devices that run on lithium-ion batteries, including DIY and electronics enthusiasts. It has a library of some of the most popular battery cell types, but you can also change the parameters to suit any type of battery.
If these conditions are satisfied you can reduce DC voltage by (high power aluminium) resistors [>50 watt] Your battery is enough to supply at least 20x (or much more) current for your load. Power loss is not a problem. (Over)Heating is not a problem or having good cooling mechanism for resistors.
When connected (negative) at the 12 volt terminal, and (positive) at the 16 volt terminal, it's a closed DC circuit, and with a 4 volt charger you would only reach the last two cells in the battery. It's a Gel Cell, lead/acid, so just charging the battery as a 16 volt battery charges all cells.
Your battery is enough to supply at least 20x (or much more) current for your load. Power loss is not a problem. (Over)Heating is not a problem or having good cooling mechanism for resistors. Even the lowest resistance of your load is much (20x or more) higher than the aluminium resistances.
?? by reducing the current into the load a resistor does both of those things. Adding a resistor half the resistance of the elements will get you down to 12V, and increase battery life by 50%, but you end up wasting a third of the energy in the battery (unless you use that resistor to keep something else warm).
