How many volts does the thing take in???5 and 12v
ReplyDeleteLets say worsts case scenario you need 12 v at 20wats thats 1.6amps You would need about ....mmm now that i do the maths. 8 2600ma nimh batteries would do the trick for an hour easy!
8x1.5v = 12v
run them in series and you will get 2600ma at 24v which is 31.2watts for 1 hour!
do it dude!
