Do you really have a 500 amp-hr battery? If so, it would be very heavy and not at all easy to move. Are you sure it's not a 500 amp "max...
Not sure what Catbuilder intends to use, but here is a belt-driven head - rated at 10 kW max, 7.2 kW continuous, 90 pounds... and only $290! :)...
I don't know what exactly Elco quoted you (motor only, motor plus controller, motor plus controller plus throttle plus gearing, etc.?), but since...
Look up the Thoosa systems by ASMO Marine. The US rep is Annapolis Hybrid Marine. The smallest system they have is the Thoosa5000 for boats from...
Hmmm... according to Aquawatt, their 13 kW is suited for displacement as well as planing hulls. But let's look at some numbers. Quite a few...
Oh, and one more option if you were inclined to go the DIY route. Get a couple of blown outboards, rip out the engines and install electric...
In addition to the Aquawatt outboards, Regennautics out of Florida has 145 kW outboard powered by a UQM motor. With a couple of these 200 HP...
Aquawatt in Austria has a couple of outboards, a 13 kW and a 22 kW. The 13 kW is around $9K, and the 22 kW is around $11.5K. You could install...
If that's a concern, you could use a full-size electric outboard (not Torqeedo). But I'd be more worried about cavitation when mounted so far...
Yes, naming conventions can cause communication and comprehension problems in several technical areas (generator vs. alternator vs. dynamo, etc.)....
No worries, mate, given your requirements, there are very few pre-packaged marine propulsion systems of that flavor available. The only one I am...
Correct, that's why I pointedly identified the Tesla cells as "Li-Ion" (i.e., Lithium-ion Cobalt oxide), and not LiFePO4. In many ways, large...
I believe I have read this guy's posts on CF ("gosstyla"?) some years ago. Quite an enemy of electric propulsion. I did some checking around at...
As a notable exception, the Tesla Roadster uses the 18650 Li-Ion cells that are just slightly larger than the AA format.
Other than a few sailing yachts, the majority of the ships attacked by Somali pirates have been ocean transport ships that are quite a bit faster...
