I'm fairly interested in electronics but not very educated in it.
I was wondering how I would go about safely converting your average li ion battery pack to a usuable voltage (240v ac) for things like bulbs and such.
I've so far got multiple packs I charge them using 5v usb chips of various kinds and run them all in series. I have a 5v solar panel which in the summer can trickle them and ive created a charging bridge from 12v dc to the 5 v dc and thus the batterys themselves and a small solar panel trickle charge (unfortunatly right now the battery is not deep cycle I know thats bad)
if you were to wire them in paralel would the voltage step up like with conventional batterys?
I was hoping I could run a 5v transformer in reverse ? but have yet to figure out the maths on how many amps I would have. I know I would need 2 diodes to make a rectifying bridge and then hoping to put it threw a 5v to 240v transformer
this is all just a spiral off my hydro / sterling engine 5v generator to battery bank for off grid basic gadgetry.
