It would be more efficent to create a 1S 4P battery pack as this woud be colser to the required voltage. this is better as the power wasted (causing your heating issue) by the buck converter (it would be a boost converter with my suggestion) is proportional to the size of the voltage change between its input and output. I loved the video btw.

That with losses being proportional to the voltage change only applies to linear regulators (which works basically like variable resistors). For a buck converter, the higher input voltage is used to store energy in an inductor, which is then released thru the freewheeling diode - which gives more current to the load than what's coming in on the input. It works pretty much like a transformer, but for DC. Same but the opposit, applies for a boost converter - energy is stored in the inductor that is then used to boost the voltage. A boost converter will always have higher input current, as long as the output voltage is higher then the input voltage. Both buck or boost converters have 90% efficiency or more, if it's a good design. I think the main problem he had with the first buck converter was that it was simply too small, so it was overloaded (which increases the losses significantly). No LEDs can be driven directly from the batteries anyway - they always need a drive circuit. It's not like a typical resistive load, such as the incandescent light bulb that was in the flashlight before. An LED can be barely lit at for example 3,8 V while it may blow up at 4,5. The voltage of the batteries usually varies way too much depending on their state of charge. The forward voltage is also temperature dependent, so they may run fine on a certain voltage when cool, then they become overloaded when they have been on for a while and get hot (a driver will usually compensates for that by lowering the output voltage slightly, to keep the current constant).

Charging will be a problem with 1s4p ( no any BMS & charging module to keep the unit safe ) . Using Buck Converter is a best solution.

Oh, I've seen same one at my home 25 years ago.

Is there a reason you always use washing powder when cleaning the plastics, rather than a dish soap liquid?

@adwol48

3 жыл бұрын

I'd imagine its because the washing powder granules might have a slight abrasiveness to them to begin with which might help move dirt easier where as the washing liquid relys on its degreasing potential. just to add after working on my car if I don't have any proper stuff to get oil and muck off I will use washing up liquid with a spoon of salt or sugar that helps greatly to remove the dirt.

What emitter did you use? Should have used a warm emitter, around 2700K to keep the same color temperature as the stock light.

Brother the led always wants excessive current that would produce more heat and there are more power losses i recommend you to use 2 lithium ion battery of 3.7 volt in parallel and remove the 12 volt lithium ion battery and also remove converter and use a 10 ohm 1 watt resistor in series to led and bateery that would runs longs

To think that before everything was done in Japan, and it lasted a long time. Now everything is disposable.

Waste of materials, why do you put a buck converter to reduce 12v to 4.12v to feed the led?? Why do you make a 12v lithium pack? You could make a 4.2v pack litiuhm and a simple tp4056 to charge the pack
