BMW EV conversion-- 40 cells installed in place

[sildenefil]

how many miles can you drive before recharge?? Do you think their is a possible way to use an alternator or magnetos with to keep the batteries constantly recharing while in use so that it may get even better milage??? Keep up the good work?

Thank you, sildenafil.

You usually have two kinds of brakes on electric cars-- ordinary friction brakes like we use on gasoline cars, and REGEN brakes that use electric motors in reverse-- rather than using energy to make the car accelerate, the motor is used as a generator to pump electricity back into the battery-- generating that energy is not free... you cannot use the kinetic energy of a car to make electricity without slowing the car... your idea would not work.

Thanks again--

@billdale1 so quick to discourage bill.

Great! I'm converting my BMW E30 too. I have a double 11" Kostov and Zilla Z1K for now, I'm currently ordering a Z2K. My batteries are LiFePO4 ThunderSky's, 100 of them.

What battery do you have?

[billdale1]

CroDriver-- what does your handle mean?

I am using Thundersky LiFePo4 cells as well... I have about 90 ol the 100 Ah cells and 90 of the 50 Ah cells. You did not say which size cells you're using-- I'm afraid you may be exceeding the safe load limits of the car. If you're using the 100 Ah batteries, they weigh about 7 lbs each, plus the weight of the battery boxes, controller, motor brackets, the adapter plate between the motor and the tranny-- prolly over 800 lbs total-- (cont'd)

[billdale1]

(cont'd) don't exceed your weight limits and you should have a safe machine. I will be using the 100 Ah cells in this car, but may buy more of the 50 Ah cells to do a similar conversion to compare them.

My biggest concern is your motor choice-- I am using a Warp 9 which is powerful enuf to burn rubber as you see in the vid-- with a larger motor what do you gain? it wil be heavier, slow you down, and may put you over limit on weight-- I'm guessing those motors will B around 300 lbs. Gud luck!

Bill, this is amazing~

TY, Jose! For more data, click the blue "MORE INFO" at the upper right and on my other video clips.

The Zilla 2K controller is no longer made & cost $6K. The 40 battery cells cost $200 each; 50 more r being installed.

The gud nuz is that "Electric Louie" of Long Beach, CA will soon have better, smaller controllers for just a few $ hundred, as well as cheaper Battery Management Systems (BMSes), batteries and other components to convert any car way cheaper, easier, & with awesome performance.

How much did you pay for the controller and the 4 batteries?

Greetings, congrats.
