I have been googling on an off but not managed to find anything
suitable. I wonder if anyone on here is able to help.
I have a home made laptop. My problem is powering it from battery. I
am looking for a battery pack that outputs 12 and 4/5 amps. However I
also want something that comes with a charger and that will provide
enough current to both keep the battery charged and power the unit
when plugged into the mains.

What you describe is correct, however, the output of the power supply that is charging the batteries is also the input to the inverter (as long as the is AC mains power).... Effectively, the battery and the DC power supply derived from the AC mains are in parallel, so that the inverter will run from either. ... Because there is no net discharge from the battery, the battery life is the same as it would be in an equivalent "standby" UPS. ... (alt.comp.periphs.mainboard.asus)
