o.k thanks for quick answer on other question.What we have thought about is running the tugboat for say 8 hours on say 3/4 volume(fairly loud) for parties.Is this possible?Is there a certain equation to figure approximate amount of batteries?can something be done with generator or some sort of charging system?we would like to try not starting boat all the time.Thanks

 

Eight hours... Yowza.... Running both those amps at about 75% output, you're gonna be drawing 40 to 50 amps, maybe more...

Well, to do it off of just batteries, you'd probably need at least eight GC's (or say, four or six 8D CAT batteries... or even more). Yep, I said eight... Roughly $1000 worth of batteries and cabling to git'er done. And that's not even discussing weight issues...

Which, is crazy.

What would I do? mmmm..... I'd probably get four GC batteries and a generator to charge. A quiet one to charge while you're using the system.

Or if weight wasn't an issue I'd get a couple used locomotive 8V batteries and go with something like that. 8v lokies are 400lbs. each, roughly 3.5 feet long, 18 in. wide, and 2.5 feet tall. My warehouse services them for western Canada and they can build good ones out of scrap ones, the cells are individual, and then sell them to remote locale cabin owners. So he could make two of them with just 3 cells each for 12v total, or even 7 cells total for 14 to 15v on tap (something I did for a DbDrag 3X event last year). Oh I think I even have a pic somewhere of them lemme look...



Oh wait darn bikini girls are in the way... :P



heheheee... Anyway, there's some more ideas for ya.

 

Thanks grizzz.I went to tug to talk to buddy and he showed me batteries in shop that they called 8d's.I believe ther the same.They use them on tugs and he has 16 of them so i don't think power is a problem any more.There huge eh!They don't look as pretty as pick but they'll work.Weight is not a problem as we just got back from putting 8 man hottub on back(in snow).If your ever near windsor send message and you can come out for party.boat holds 100 pretty easy and i'll put picks p when we are done(probably 2 weeks) Thanks again.POONER

 

maybe they can get those batteries working at 17 volts to run them MA audio high currant amps.

just got 2 of these and the big 4000 watter
obviuosly gonna need the power.
