Automatic Battery Charger 6V-12V with Relay cut off by LM324

This be battery charger the automatic circuit again interesting circuit. Because of use IC LM324 then make economize. And can charger get both of battery 12V sizes and 6V with the filtration that at S1. Certainly circuit this still base property be when battery have voltage full already, circuit as a result order give Relay RY1 cut the system departs battery immediately. For R1 and R7 use for fine decorate the rapidity of the circuit. The test is as a result easy. Lead the battery that have Full voltage wasp with the circuit fines to decorate R1 and R7 give RY1 work. detail other part see in circuit picture sir.

*** Note: Though This project is good but it may difficut to build and expensive. I love this projects better : Simple auto cut off 12V battery charger

Next circuit that I want tell you to see. They have IC-555 and LM340 as main components.
Although them are old circuit more 40 year old, but I think so well if you have fully the parts, ready to try build them.

  1. if I have two 12V 12AH with Series Connected for 24v to supply a motor/Scooter and I would like to charge with 24V. how about the circuit gonna be.

  2. please send me the working detail principle of ” AUTOMATIC BATTERY CHARGER 6V-12V WITH RELAY CUT OFF BY LM324″

  3. please send me 12v 24v 200ah battery solar charger circuit diagram lm324 low batt cut ch high cutoff
    low bat – load cut please send me circuit


  4. Hello, i think that i saw you visited my web site so i came to
    “return the favor”.I’m attempting to find things to improve my site!I suppose its ok
    to use a few of your ideas!!

  5. LM 7812 will cut-off volt to battery at default, you know that, charge battery 12volt, must volt begin at 13.5volt. it’s cant for Lead acid battery cycle use (14-14.8 volt)

  6. Please I need an automatic(start charging and stop automatically) 24 vots 7ah lead acid battery charger for my project. Thanks in advance

  7. sir, i just start learning electronic
    would you please send me or post the pcb lay out for outmatic battery charger 6v-12 with relay cut off by LM 324
    thank you very much for your support
