Re: [Electric Boats] Electric Yacht system

 

Don,

I'm familiar with Electric Yachts and was wondering which of their systems that they recommended for your boat. I assume it was either the 100ib or the 130ib and that you'll be running 48v. I see that you're planning on using 4 group 27 batteries which should give you about 2.3 kWh usable storage. You may find that you get less than an hour at 50A before you're down to a 40% charge. The good news is that if you add another battery bank in parallel, your effective range more than doubles because each bank is getting hit with half the amps and batteries have more capacity at lower discharge rates.

My plan is to get my boat running with one bank and add another one after some of the kinks have been worked out. It also will give my wallet a chance to recover a little before the second round.

I'm looking forward to hearing about your actual results.

Fair winds,
