Lithium vs Lead; the Great Cost Debate.

Posted 02-03-2009 at 01:21 PM by mattW

I've decided to try and work out the cost comparisons for a Lithium pack vs a Lead pack for a set range and a set number of years. Is Lead Acid actually cheaper or does is just seem that way up front? This article aims to find that out. The method is to get 10kWh of usable energy, Ill try to get that with Lead and with Lithium and see what we find is cheaper in the long run. Assuming an efficiency of 250Wh per mile (a compact car) we should get a range of 40 miles (65km) with either pack. Ill...

Hello All,

Found a great little download that has a bunch of great electronic tools. Electronics Assistant is a Windows program that performs electronics-related calculations. It includes a resistor colour code calculator, resistance, capacitance and power calculations and more. Details of calculations can be saved or printed. It provides all the functions found in the calculators section of this site and more in a stand-alone user friendly program.

Update: AO3 Trans to 11" Warp Motor

Posted 02-16-2011 at 02:38 PM by FB Performance Trans

UPDATE: We recently completed the retrofit of the AO3 transmission to the Net Gain Warp 11 DC Motor.
http://www.fbperformance.com/viewtra...smissionID=101
We were able to use all of the same Adapter components that weve been using for the 9 Warp motor. (See photos attached to the opening post). This is because the larger motor uses a face plate which is very similar in design and the output shaft has the same diameter.

This EV conversion is going to be used...

Better late than never

Posted 03-31-2012 at 05:28 PM by kc7ekk

I converted my 1992 Toyota pickup to all electric on Sept 2011. I have driven it to work and back 40 miles every day for the past 6 months. I have put over 6000 EV miles on it now.
I have continuously been making efficiency tweaks to it.
Check out the improvements:
Initially 118Amp draw at 50mph
Added low rolling resistance tires, replaced wheel bearings, added aero mods, reduced extra weight by 150lbs.
Now the current draw at 50mph is only 90 Amps. ...
