using laptop battery as second battery
can it be done?
I have a practically new laptop battery and I would like to use it as a power source for my carpc when it is in sleep mode, I just dont have any idea on how to setup the wiring for that.
the battery is rated 10.8V 4400mAh 48Wh
I know for a battery to charge the input voltage has to be higher to create the 'push' needed to charge.
my question is basically how to wire it to my m3 atx power supply, because the m3 atx will turn off the 5v rail if the car battery will go below 11.8V
any thoughts on the matter are welcome :)
