I think it better to leave it to a professional who has the necessary experience and training to get the job done right.
The old rule of thumb was car weight divided by ten, times KWH of battery gave you miles range kinda ofThanks everyone, guess car batteries just aren't feasible, shame I really wanted a refurbish-able battery. nicolaskn, mind me asking how much range you get and where you put them? That sounds like a better option.
Great answer, but useless.I think it better to leave it to a professional who has the necessary experience and training to get the job done right.
5200*2*10/3300 = 31.5 miles on two Tesla MODULES (not cells), assuming you can find a 48V motor of sufficient power to run a 3300 pound car, and assuming the modules can deliver the sustained current at that power which they cannot.That's a great equation to have (even if its ballpark). I think I did it wrong though because I did 3300lbs/10x 5.2 (2 battery cells from ev west) and got 1716. Battery technology must've gotten a lot better, or more probable, I did the math wrong 😬
Thanks Floydr that sounds a lot closer. I'll be saving that on my list of equations for the rest of my life. I'm just using 2 batteries to see how many I can expect for 2 so I can know what to expect when I add more later. I know you get more running in a circuit or parallel but its been a long time since electric class (as you can tell), you always wish you pay more attention later in life. Anyways, figured id just run lowest estimate atm.Try car weight divided by ten, divide the Wh of battery by 330
You did the math right. 3300/10*5.2=1716 the formula went wrong somewhere along the line.
battery technology has gotten better but 5.2 kWh is still 5.2 kWh
