I don't doubt he had a hard time catching a turbine boat. Think about four monster big blocks at say 1400lbs each, then four 6 drives at over 500lbs each that's almost four tons on the last 10 feet of the boat. How did Xhibit get on plane without sinking lol.
The weight I would say anywhere from 17,000-20,000lbs.

G, lets get the tub out early ! Boston Harbor looked like a mil-pond today and the sun was high in the sky. what daya think ?

Hey the phaggot pizzed me off so I had to represent. That'll teach that phaggot not to mess with a ol dog.

BTW, any pics of the new MyWay?

G, ANY NEWS on the Lithuim batteries ? pricing and weight ?

These batteries are amazing.
36lbs one battery will run the whole boat.
I,m going to run a dc to dc converter for the 12 volt side.
I,m running six optimas at 39lbs each.

Going to need a 12 converter to run 80 amps continuous.
Start one turbine with the lithonics battery then turn on
the start generator on the running turbine. The generator
will supply 350amps 24v. Lithonics claims there battery wont need it.

Gerry,
A couple of questions... Are there any special charging requirements? How will they hold up to the typical offshore abuse? Life span?
Just some random thoughts on what I know about LIB. Connecting several small batteries in parallel is more typically more efficient and effective than connecting a single larger battery. I believe these batteries require some type of battery management system to keep them stable and consistant. They usually have special charging requirements and degrade over time (taking less and less of a charge each time). It doesn't take much to damage them and any damage is irreversable. As I recall, they are generally fragile and often need a protective circuit to limit peak voltages.
I don't know a lot about these batteries, but you may want to look into these potential issues before dropping a couple of grand on a LIB, you haven't already.
Keep us posted with what you find!

Great thoughts! I was curious on the charge rates myself
I copy and pasted your questions to the senior engineer and here is his response.
Hi Gerry,
A lead-acid battery is made of small, fragile lead conduits that break under boating stresses. Take a look at how our batteriesa are made inside! They are tested to 150 g's on X, Y and Z axis. No lead acid battery can pass the DOT test for lithium.
Charging: any alternator build after 2005 is acceptable for lithium.
Recharging and Life: see attached cycle-life curve....our batteries do NOT start wearing out until thousands of FULL (not partial) discharge cycles are realized.
All we can do is give the facts, speak with data, and let you make your own mind up. At the end of the day, this is what it's all about...
