12V Battery Protection

Hi my name is Steve and i'm a Creative and I got Technical skills i can build anything just stick...

Intro: 12V Battery Protection

Hey! everyone My name is Steve 19 year old from India

Today i'm going to show you How to make a 12V Battery Protection Board .

Very Low Current Consumption Only 1.5mA

It will protect your battery from Over Discharging



• Cutoff at 10.6V
• Re-Connect at 12.5V

  • Printed The Layout
  • Cut The Copper Clad
  • Press With Hot Iron

See The Image For More Information

  • Put The Copper Clad On Ferric Chloride
  • Remove the Ink
  • Drill The Holes

Step 4: Solder

  • Solder the components

Step 5: Connections

  • Solder The Connector For Inlet And Outlet

Step 6:

  • Hot Glued The Wire to prevent from loosing

Step 7: Finished

  • Just Plug The Battery and you are Good to go

    For the power MOSFET you can use a IRF1404, for the same price if you stay below 40V, that has a lower RDSon resistance and will therefor allow up to twice the maximum current.

    Very nice module, since low power consumption is crucial. Thanks!

    Hi i was wondering if this circuit could be modified to have adjustable cut off. I was planning to use this in a daah cam. So im looking at 12.2 as cut off and 13 as turn back on

    Thank you
