For a little bit of info, I have an old 91 Acura Integra that has been lightened a lot. I've got a 5-speed transmission and LOTS of room inside of the car and under the hood as compared to smaller cars. The car isn't as light as a Metro, but it's pretty darned light.
I've done research and figured that I could roll with an:
--ADC 8" dc motor
--Curtis 1221c (400amp) controller
--Curtis 1400 (or something similar) dc-dc for my lights and items like that, which I wouldn't mind using a independent 12V battery with an alternator setup off of some sort of secondary motor output shaft to power the independent 12V battery.
--Elcon charger (i'll have to get accustomed to selecting a charger designed to charge approx. ten 12V batteries at the same time)
Now, the problem(s):
1) I'm stuck on which Ah rating I should focus on when selecting a 12V battery. It only makes sense that a larger Ah rating is better, but does this simply mean that the higher the number the more of a beating the battery will take?
2) I'd like to think that I could stuff as many batteries in the car as possible, which would be great. However, why stuff more batteries than the 8" motor and Curtis controller will handle (more batteries = more voltage)?
3) I'd like to commute with the car, and had my mind fixated on 50 to 60 miles. I have this great suspicion that i'm going to be disappointed. Hey, the lead battery route is the game I may have to play. I personally have experience with lithium batteries in other area's of trade, and I know enough about them to know that they're definitely NOT cheap.
4) What about those sealed 12V 10 to 15Ah (saw it on one of the EV supply sites) batteries that were like approx. $50 or so? Also, I couldn't imagine a billy bad Interstate battery being worth a darn. Perhaps an Optima "red top," but I just don't see that being a good idea and I see myself getting poor results.
Overall, i'm stuck on the battery deal. Most of all, I think my combo isn't going to get close to 50 miles of range even if driving easy at around 45'ish mph. I'm not looking for someone to just tell me what I want to hear. I mean, hey, let it fly. Be honest. It saves us all some time.
