I'm using Odyssey TPPL batteries in an electric refit right now. The bank consists of 24 Odyssey 2250 batteries for a 326v bank (at float). I'm driving a 50kW UQM motor as the propulsion motor, a 10Hp Emerson motor for driving the hydraulics, and there's also a 7kW inverter, and a bunch of DC-DC converters. I looked at LI-ion but the cost is about a factor of five higher. I would have needed a $65K battery bank.
The generator for my rig is a 40kW Westerbeke genset with 240vac 3-phase output. This goes to a water cooled full-bridge rectifier to generate DC for the bank.
As we move to sea trials, I'll report back on the experience with the TPPL batteries.
