Alright so i am in a state of despair trying to decide on what batteries to go with. Due to cost i am almost guaranteed to go with Lead-Acid, (i cannot really afford more than about a $4000 battery pack). But i have looked a number of different brands and types and am pretty unsure.
My planned conversion is a Mk3 VW golf coupe, with an initial curb weight of about 2500lbs. I am going to use a Netgain Warp 9 (or an 11" if the weight is looking high) and a 144v system (750amp WarpCore Controller).
My final contenders are looking like 18 of the Trojan T-890 rolling in at 31kg (70lbs) or 12 of the T-1275 at 37kg a piece (82 lbs). I picked trojans partially for their famed durability but primary because they were the only batteries that i could find with A/H ratings over 150. To sum up i basically have 3 questions,
-I am hoping for aprx a 50km+ range (31+ miles) how many amp hours should i allow for? The T 890s provide 190, and the T-1275 provide 150. Do i even need that many amp hours or should i be looking at something like the Optima Yellows tops in a 75 A/H configuration?
-With my total curb weight sitting between 3500 and 3800 lbs should i be looking at the Netgain 11 inch motor (or even a 13"?) instead of the 9? I don’t want to end up much below stock ICE acceleration. Will 11" motors drop my efficiency considerably?
-Am i at all in the right direction with my components considering the weight of my car and my hopeful range?
I would also like to mention i am not completely without an clue lol i just have not been able to get a really firm idea of what i need because my conversion is looking considerably heavier than most.
Thanks so much!
