- Correction! When I say Current Eliminating, I mean Current Limiting or Regulated Current.

This is a fantastic Super Capacitor for Car Amps
This will also work on Nesscap and other Super Capacitors - วิทยาศาสตร์และเทคโนโลยี
This is extremely helpful. I've watched dozens of video's with ppl directly connecting in their cars and never any mention of these important facts. In fact, I may have even damaged my car computer doing that. Understanding the burst factor of everything outputting at once (short circuiting) is really important..
Thank you!
This is very helpful. It's good to know how to do this safely. On my end when charging the supercap below I think I just lucked out.
I realized when I received the Supercap that it was about 1.5 volts or so and that my lithium battery chargers would fault based on undervoltage. I hooked up a voltage meter to the circuit and used a 12v power supply (1.75 amp) and turned the power switch off and on every second or so until it gradually built up to the necessary voltage to be recognized by the charger (it seems like this was around 9 or 10 volts) which could then take over. It appears that with your light bulb assembly I would have not needed to be the "manual" power limiter, but the bulb could have taken my place without any intervention needed on my part.
I have a question that I'm facing with an application of a super capacitor and it seems like you are someone who could help me find the answer. I don't have an electronics background, but I'm generally really handy/capable at finding and implementing solutions. I'll put the question out there, in case you'd be willing to give me some pointers. I apologize if this is hijacking your thread. If I knew where to find the answer I'd go there. I'm still trying to find the answer.
I'm using an LifeP04 battery in place of an SLA battery to power an automatic gate opener as the sole power source for the gate. I'm using an adequately sized solar panel to charge they system and the battery size of the LifeP04 battery is 55 AH. The SuperCap is 16v 500F. I'm not sure of the load of the gate opener, but it's not huge. From what I can tell, the BMS in the battery is activating an undervoltage protection for the battery occasionally, as occasionally the voltage drops into the 10v range and the gate control faults and stops the gate. It takes a reinitiation of the gate control to complete the gate cycle as the gate stops. I've purchased a SuperCap to run in parallel with the battery to help it get over the excess load during the peak draw and want to limit the amount of power that can be drawn from the battery before the supercap has given up the power first. I'd like to limit that drawdown of the battery to around 11 volts. My intention is to install a resistor on the battery side to accomplish this. I just don't know the size. I've seen misc. sizes from automotive application videos, but the one that identified the voltage during the drawdown was going to less than 11 volts. Would you be willing to offer any pointers?
Also, now I'm curious... If I understand correctly - a potentiometer is a variable resistor. Are there (heavy duty/affordable/readily available) potentiometer's that would be safe for this current range that I could simply dial in to get into the voltage range that I'm trying to stay in? This would help if my guess of 11 volts isn't the right guess as I could just do a quick adjustment until the gate functions correctly. Even if I only used the POT to test/establish the ultimate size of the fixed resistor... and then installed a fixed resistor.
Greetings, I need to know the normal current draw of the gate opener, and the maximum current draw in case there is an object blocking the gate. If the gate gets stuck, I need to know if the motor continues to force the gate to open or will it give up after certain amount of current draw.
Thank you for your video, Just to clarify... I am putting a 500F 16v supercapcitor before a 12V inverter (being run by a Lithium 12V battery.) What your saying is to connect the capacitor in parrarell with the system I already have, charge it first to full capacity as shown in your video with 50 watt globe and then once fully charged (light goes off) connect it? Once it is connected the battery the voltage between capacitor and battery voltage should eventually go to equilibrium ? ... please advise 🙏 thanks again..
Yes that is correct, you could charge it directly without any bulb if you have a regulated power supply. Otherwise the current rush to the capacitor will overload your power supply, and if you use a small gauge wire you will have the potential for overheating wires and which could cause fire.
@@TECHNOLOGYTIPS101 Thanks 👍
@@JCMW-hw9jl You are very welcome!
how can we charge the ultra capacitor module fast?
if we are connecting the ultracapacitors parallel to the battery in trucks or car will the capacitor charge fast enough to crank the engine during frequent starts and stops ?
Yes but you have to first slow charge it and when it is 100% full, only then you can connect it parallel with the car battery. Otherwise, the wires will get hot and possibly burn from excessive power rush to the capacitor. The capacitor can take 1000 amps or more of electrical current in one second, which is the same as shorting out the battery terminals, which could damage your battery.
@@TECHNOLOGYTIPS101 In automobile system if supercapacitors are installed the current rating from the alternator is it enough to charge it fast.
to protect the battery from damage we can give a current controlling device like DC-DC converter between battery and capacitor, but to charge it quickly after one crank what will be the ampere rate at which it should be charged?
and datasheet or schematic for the balancing board, is it available can you share it
@@ABELELDOABRAHAM When the Super Capacitor is connected in parallel with the battery their voltages will even out and reach equilibrium. In such a case, there will be no current flow to either direction between the battery and the capacitor. However in order to reach equilibrium for the very first time when the capacitor is completely empty you must do a slow and regulated charge unless you have a DC Power Source that can handle a sudden current flow of hundreds of amps. Even if you do have such a power supply the connecting cables must be secured tightly before the power supply is turned ON, otherwise, you will have arc, spark, overheating, and fire. I have even witnessed cases where the charging cable terminal melted and got welded to the capacitor screw post. You can get the data sheets from here maxwell.com/products/ultracapacitors/downloads/
So are you saying the manufacturer is incorrect and just letting you hook up the ultra capacitor to the battery. Would you have any input and why the ultracapacitor that I have which is a Maxwell 31 group semi truck starting module will not charge past 12 volts , it all of a sudden after two years old stopped charging past 12 volts
The way they are wired from the factory for the Vehicle starter, there are three wire terminal posts. One goes to the Vehicle Starter, the other one to the battery's positive terminal, and the third one connects to the ground. So, the safe charging circuit inside will do the trick. About your Capacitor not charging past 12V, it could be two things, either a bad " Capacitor Balancing Board" or a bad " Alternator"
@@TECHNOLOGYTIPS101 thank you for your prompt response it's not the alternator I've already tested it I've taken out the Maxwell capacitor and replaced it with the battery in the meantime is there anywhere I can access information to text the balancing board or is there anywhere I can purchase a new balancing board thank you for time

Hi,
I have 48v 83F Supercapacitors in series with 3 parallel supercapacitors ( each of 62F, 18v).
I want to charge it directly from 48v battery.
What things do I require to consider for safe charging?
hello sir i have 6 2.7v maxwell super capacitors 3000f connected in series how many amperes and voltage of light bulb i should use ?
That depends on your charger's power and wire gauge, because the capacitor can handle over one thousand amps and there are very few power supplies that can handle that. So if your power supply is 100W which is 12V 8.3Amps you can only use one 100W bulb, for a 200W power supply two 100W bulbs in parallel, for 300W 3x 100W bulbs in parallel etc.
@@TECHNOLOGYTIPS101 i will use 13.5v 50a regulated power supply with 8awg wire is it ok not to use bulb ?
@@kunhei_the_Ben As long as you can regulate the current not to exceed the maximum you should be good. Start with 1Amp and work your way up as the Capacitor charges. If you choose 8.3Amps which is the max, the power supply will heat up and the voltage will drop to very low voltage. Remember that connecting your power supply to a fully discharged Super Capacitor is like short circuiting the power supply.
Where's the link for the bulb??
