What's the cost per kWh of your LiFePO4 batteries?

[MetroMPG]

I'll be surprised if you get a response...

I suspect this is just link spamming. I've deleted the poster's contact info/web links. Interested parties can PM him or reply to this thread and see if there's any reply. I doubt it, but we'll see.

Thank you for your response. please send me an email. I need more details on your EV. So would you please advise us the motor power of your EV ?And the working current and peack current ? some tech. datums of the the controller? The weight of the vehicle ? your expect mileage? I am looking forward to your email.

Well MetroMPG, there you go

Maybe you can get some deal for batteries on the Forkenswift? maybe an endorsement or something? It could benefit both parties for research.

Hmmm, lets see. Assume I'm using 50 of the 120AH cells. That should give me ~25kW max continuous and ~50kW pulse with ~50 miles of range in a compact car.

Hey, no assuming!

We have (at least!) 3 perfectly good cars to use as real-world data sources!

Mine is 72V system.
6x100ah lead acid gel batteries.
20 HP motor and gets a 20 mile range!

maximum power draw is 400 amps at 72 volts

[roflwaffle]

What kinda voltage sag are you looking at Ben? That's ~29kW peak assuming the batteries stay at 72V, and even w/ losses you should be 25-30hp unless you get some serious drop.
