hi guys, this is my first post and i know this is going to be a basic question for you guys but until you tell me the answer i dont know, i got the 817 to go out and about with not much weight but the battery life is not great as explained clearly on this site so i want to carry some more power for 8 hours now reading the posts here it seems that lipo power is the answer, now this is my silly question do you cut the output wire plug off ant solder on a jack plug and the put that in the 13v supply? or what, thanks in advance, steve m6ndq?
