Ok first this is PURE fantasy dreaming right now. I don't have the $600 for the pack or $600 for the controller etc.. to do this its just "sounding board" time.

IE reality check to see if my fantasy is even feasible.

I want an EV. I can't afford one and a Lead powered one will not work for me (commutes too long 54 miles)

but one thing I have been thinking about is a "sort of" hybrid of sorts. I have a wee trailer for my mouse and I was thinking maybe I could make that trailer into an electric car that attached to my mouse and use it to "assist" me.

the idea would be this. when I let off the gas to slow down I kill the engine. at the light engine off. when its green engine off use the electric to accelerate to speed and then restart the gasoline engine and turn off the electric motor.

if I can do that right there I should be able to boost my fuel economy to 75-80mpg maybe even 90mpg (I am currently getting 49-50 in the winter 54-55 in the summer on E10)

so I have been trying to figure out a way to make a non lead affordable battery pack.

I found this interesting battery pack for around $150. 37volts 5000mah 15c

Now do I understand this 15c thing right. this pack can output 675 amps or power?

if I am correct on that this means 4 of these would get me a 148volt pack with 5 amps of capacity and these batteries can dump that full 15c or 675 amps for around 8 minutes.

if 1c is normal discharge over 1 hour IE 5 amp load them 15c would be 1/15th of an hour or around 8 minutes.

if it takes me 30 seconds to accelerate from 0 to 45-50mph (my normal cruising speed) that means 16 full accelerations IE more accelerations than I need to get to work. (figure I need 9 to 15 acceleration depending on how well I time the lights and or lucky I get :-)

since this would be an AC system I could even use REGEN.

am I doing my math right or did I really screw something up? that would be only a $600 battery pack !!! thats almost within range of being doable for me !!!

maybe I could even do a DC system 74 volts would only need 2 packs or still get 4 and have 16 minutes of full power but no regen. (and go gentler on the packs)

I must be doing the math wrong seems like too good to be true or something.

I mean at 8 minutes per set of 2 at 74 volts that means $3000 worth of lithium packs would get me my full 54 miles to work even if I drew 100% 15c from them the whole time which I won't off course so probable a $2000 pack would do the job.

feedback?
