hi everybody, this is my first post. im not an expert in circuits and i need a little advice, im planning to build a battery pack for a pstwo and i was thinking about using some 9v rechargeable batteries connecter in parallel to increase the capacity of the battery since my pstwo houseplug adaptor has a DC output of 8.5 volts and 5.65 A intensity.
if u dont mind helping me out, i got a few questions.
1) could a 9v output instead of a 8.5 output damage my console somehow, if yes what would be the best way to down regulate the voltage, my guess is a weak resistor but im not sure if that ensures a stable voltage. could a simple capacitor solve this?
2)can a series of 9v batteries connected in parallel give out an intensit of 5.65 A by it itself?
3)approx. how many rechargeable 9v batteries should i put toghether to get a good 2-3 hours of power, the lenght of a movie at least.
4)what wold be the simplest way to add a 'charge meter' or simply a led that tells me the battery are almost empty so that i can turn the console off before the power runs out
5) maybe im asking to much but if the whole thing becomes a bit complex....could someone post a circuit diagram, please.
any help will be apreciated
