Re: [Electric Boats] Re: Corvus Li Based battery .. designed for Marine Use

 

They where closer to twice the price of a other LiFePo4 and a BMS, they looked nice but a little pricey for my taste.

I think you'll find you can get about 17KWh of CALB LiFePo4 for that same $9K. And you can do it tomorrow, off the shelf.

I've been running an 8.6KWh LiFePo4 pack for 8 months now, no isues to report. Well, maybe one. I originally planned to use AGMs, and now I'm floating 600 lbs light. I need a bunch of lead to bring her down to her lines! Maybe I'll ballast her with AGMs.... :)
