      No matter how big is your battery is it will provide only amount of current the device need* and he is saying this because all other people are using lipo battery without any protection or proper voltage regulator and you can use battery directly in EMERGENCY coz batteries drop voltage while using and device components well get heat up if there is insufficient voltage so its better to use regulator and booster 👍🙏

    The relay would not trigger unless I used just one 9.1V zener for D5, (not sure why the 9.1+6.2 did not work). I've also found using a ~2200uf capacitor across the output will stop the router resetting when it switches. All working now, it seems thanks again for this project, very informative.

    @zacsonskaria Před 4 lety +4

    Considering that the power-supply can simultaneously charge the battery and provide sufficient power for the load, you can connect the load directly to the battery and design the charger to adjust current based on the requirement. This way you can avoid those relays and the supply to the load will be smooth.

      @Beanie1984 Před rokem

      I agree with the other person commenting as well. We should not use battery 100% of the time, only when needed. A nice special feature would be to drain the battery about once a month to keep the battery healthy. However, knowing my luck, the power would go off once a month while draining the battery lol

    At what voltage will the battery stop charging? My concern is that the voltage drop across the bridge rectifier will mean that the battery will never get the full 15V, hence the ups that is calibrated to stop charging at 15V will not stop trying to charge it?

    Hello Mr Usman, I finally received all the parts including the 15vac transformer. Like someone else noted, I had to use only one 9.1 zener at D5 for K2 to switch. The circuit runs fine in the normal power mode. However, several minutes after removing the AC and running on the battery, K1 relay starts clicking or chirping and the charging LED blinks, the 555 timer starts getting hot. Any thoughts what might be wrong?

    what if the input is replaced by 12v ?

    Brilliant Usman.
    Is it possible to modify it as follows:
    1. Add (12V emergency light output module) to design.
    2. Make power source 12V/ 5A instead of 15V
    3. Make output 5A.
    If yes, I offer you to sell json file to me.
    Waiting for your reply.

    Thanks for the great video! Noob question: can you add more batteries for a longer running time?

      In parallel, yes, using batteries of the same rating.
      -Make sure voltage of the two batteries are the same (can use pcb to charge separately before next step if needed)
      -Connect batteries positive-positive & negative-negative.
      -Connect pcb to positive of one cell & negative of the other (if using > 2 cells, connect pcb to positive of the fist cell & negative of the last cell)

    Mr. Usman, I want to ask, are the GBU8005 adn GBJ2510 diodes the same? I have a hard time finding it on the market. Or can it be replaced with another code diode? I hope you are willing to reply to my comment. Thanks very much...

      You can use any 100v or above diode with current capacity of 5Amp or above.

    is there battery protection if battery goes down and should be cut off!

    what is the output current rating of this circuit. does this manage battery charging also.? I made one on my own circuit, but i failed after some months.
