Doing the calculations its seems my car runs @ roughly 150-200 amps cruzing (aka50mph or so) I get approximate 25-50miles range (though my speed reduces as I go) 50 miles is at 35ish without much stop and start and the batteries are almost dead. My guess is via peukert I have only about 80amp/hr available and I probably never exceed 60ahr due to the way my controller operates.
So lets say my real range per 60ahr is only about 20 miles (conservatively) that should mean I need 72vx300ahr of lithium batts to go 100miles?
Am I about right? I have seen many discussions of lithium batteries in cars (not counting scooters) But few seem to state decent ranges (better than what I get) and the cost is huge.
On this regard I can possibly get damaged batt sets from wrecked prius and insight setups very cheaply, are they really only 6a/hr 144 or 320 volt? That would mean I need roughly 20 batt sets from wrecked cars assuming all cells function which is unlikely.
Anyone ever go down the road of getting a prius or insight batt set into something else?
I have been watching the so called firefly batteries but according to the white paper they aren't much better than normal lead acid, am I wrong?
Just curious what alternative battery setups are out there, especially in the salvage side of things (I like cheap rather than crippling debt) I have also looked for the military Nicad batteries but they never go up on the govliquidation site.
Also what do you guys think of the thundersky / everspring lithiums? http://www.evforum.net/forums/showthread.php?p=1061
Thanx for any insight
