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.
Lead acid battery Charger 6V -12V By 555 and LM340
Here is circuit lead acid battery Charger 6V -12V.
I use IC 555 and LM340. Read Detail more in image circuit.
Note: In addition, you can also see this circuit using LM317.
