Hello! I have a good question to about the possibility of making a descent power output on batteries on tesla model vehicles s and 3. The batteries that are 3 quarters inch long placed in a cell at the bottom of those vehicles. It costs 4 to 5 thousand to replace the cell if damage or not reusable with a 8 to 10 year warranty free service. Each battery cost 20 dollars to replace lithium ion battery. I would like to know if you can come up with a solution of an output equivalent for 5 dollars instead of 20 dollars on the it's power efficiency to put on the cell that is 3 quarters inch long. Using the math of hours of amperage and Faraday in mathematic formula. Please if you can send me a message about this, please contact me. Thank you!!
