In this video, I will show you how easy it can be to design your own Automatic 12V Lead Acid Battery Charger Circuit Board and have them manufactured professionally at https://jlcpcb.com JLCPCB is the largest PCB prototype enterprise in China and a high-tech manufacturer specializing in quick PCB prototype and small-batch PCB production.

You can use this circuit to charge12V 1A ~ 12V 7A Battery.

List of Components:
R1,R3 = 1K https://goo.gl/4XW5DR
R4,R5 = 1.5K https://goo.gl/V1jUMS
R6 = 10K https://goo.gl/RVB6fy
R7 = 1.2K https://goo.gl/7pZQ96
R2 = 1R5W https://goo.gl/Yq1ouh
PR1 = 50K https://goo.gl/S94qgc
Q1 = D882 https://goo.gl/VbDHWe
D1 = 1N4732A https://goo.gl/2hcQtB
D2,D3,D4 = 1N4007 https://goo.gl/CqfNDo
Relay = 12V https://goo.gl/t87Jg3
U1 = LM7815
5MM LED = Red,Green,Blue,Yellow
Alligator Clips = 2
Jumper = 1 https://goo.gl/1xS713

IMPORTANT NOTE:
I designed this circuit to charge your battery @ 70% to 75% only due to some safety reasons. If you want to make it for 100% charging, then remove the LM7815 and connect directly 18VDC supply and set tripping point at 15.8 ~ 16V. and always use 5 to 6 times lower charging current from the maximum value of battery current. i.e 1.2A for a 7AH battery.
*This circuit Has not any current limiting feature.(except 1R5W Resistor)
**This circuit is not 100% Perfect, but it is still very useful for hobby/DIY projects.
***Make it at your own risk.
