How to Make Automatic 12V Lead Acid Battery Charger Circuit Board

Get 10pcs PCB boards for $2 & Big Shipping discount on First order:
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 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
R4,R5 = 1.5K
R6 = 10K
R7 = 1.2K
R2 = 1R5W
PR1 = 50K
Q1 = D882
D1 = 1N4732A
D2,D3,D4 = 1N4007
Relay = 12V
U1 = LM7815
5MM LED = Red,Green,Blue,Yellow
Alligator Clips = 2
Jumper = 1

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.

How To Make 12 Volt Battery Charger Indicator At Home Easy

In this video i will show you
How To Make 12 Volt Battery Charger Indicator At Home Easy


Easy to Follow First AGM Battery Bank Parallel Configuration 2 qty 12V 35 AH VMAXTanks AGM Batteries

This video will show you how to connect two VMAXTANKS 12 volts 35 AH AGM Batteries using Parallel Configuration with charging cables. I also wired charging cables to the batteries. This video will also show you how to charge multiple batteries using one charger or maintainer. After wiring the batteries using the parallel configuration, the charger, as far as it can detect, it will treat your batteries as one unit. The catch… get the appropriate amperage for the charger you can afford for fast efficient charging. Pay attention to the manufacturers recommendation. VMaxTanks recommends a 3 amps to 7 amps chargers – DO NOT Exceed 7 amps.
I got the 5 amps Model 1205 VMTanks Smart Charger. This smart charger falls between better and best (based on AH). Smart Charger 1207 is marked “best” for 45ah to 75ah

Parallel Configuration keeps the batteries’ voltage at 12 volts but doubles amp hours (two identical battery configuration). These VMTanks AGM Batteries will be used as a power source for my new Newport Vessel 55 trolling motor.
My first AGM Battery Bank 2 qty 12V 35 ah VMAXTanks Deep Cycle AGM joined using parallel configuration
With 2 qty of 12v 35ah joined using parallel configuration, I ended up with 12 volts 70 ah

Application: These VMTanks Batteries will be used for my 55 lbs Trolling Motor and as a backup power source for my travel trailer.
While in the trailer, the charger will be charge using the smart chargers connected to AC power in my travel trailer.


SkyRC B6 Nano battery charger: Scan-to-Go with mobile APP for easy charging – BEST FOR LESS

If you like the small and very capable ISDT Q6 chargers, you will definitely like the B6 NANO charger from SKYRC!

The form factor is similarly small, the max charge current is higher, it has 3 discreet touch-sensitive buttons and a clear and simple screen layout.

Paired with a mobile device via bluetooth and using their app, you can control the charger from your phone or tablet, create charging / discharging presets and also print out QR Codes for the Scan-to-Go feature!

You can also monitor the charging progress from a distance, through the device, but you are of course not advised to charge unattended by any means 😉
