Hi All

I am using LiFePO4 (BP2603 Tracer battery) for my camera to power up. But the problem is when it is fully charged it goes to 13.7V and the camera I am using not able to power up. It needs 13.5V to work. So could anyone can suggest me with the solution, how to discharge 0.2V by that the camera powers up.

Thanks in advance.

 

How much current does the camera draw? With the current known a resistor could be inserted in series with the camera. You only need to drop about 0.2 volt.

Maximum 3A. yes I need to drop 0.2 volt

 

A bit unusual but 3 amps at .2 Volt is only a 0.06 Ohm resistance. I would think lead resistance would be greater than 0.06 Ohm. You can try a 0.5 Ohm 2 Watt resistor in series with the camera. Another trick would be if you have a small section of nichrome wire, like a piece of a small toaster element wire or a small section of wire from a hair drier heating element. You may have to experiment a little to get the desired voltage drop depending on lead resistance.

Thanks for your help. I will try this.

 

Post back how it works out for you.

Hi

Sorry I've managed to do with a 0.6V Schottky diode.

 

Good and glad it worked out for you.
