Default Super 400 Ah LiFePo4 Lithium prismatic battery's

Does anyone know anything about these? I am thinking about coughing up the cash for 54 of them but I want to make DAMN sure that will do it! $118 each. About roughly how many Ah does a car (Heavy Bug) with a motor like the warp 11 use going 70-75MPH use? (ballpark) I am trying to figure my battery options. Any suggestions would be greatly appreciated! Also I would use these for the 12V ACC (4 in series) too right? I go round trip to school 88 Miles and do not want to hurt the pack by draining it to low, would this do it (Winter too!) or would I need to step up to the 160Ah or 200Ah version for that? I really want to do this right the first time! Thank you all so much for helping me today especially Ziggy and Paul! I have learned more in one day on this forum then I have in the whole time I have been looking in to EV's combined!!! Good night all! Thanks again for any and ALL advice!

Goddti, I have since realized the deal with those and I think the 100 Ah X 54 maybe the ticket. What do you think?

If you want a 88 mile hwy bug, check out Corbin's build:
http://www.corbinstreehouse.com/blog.../electric-bug/

I don't remember how much weather proofing he has, but for cold weather you'll want to plan on well insulated battery boxes and some form of heating, like heat tape or similar.

Cool thanks! I read about it but didn't see what kind of setup he has. I tried to download the article but it took me to a dead link. Do you know what kind of setup he was running?

Hi. Did you say 400Ah prismatics at $118 each? Something doesn't add up there. That's typically the 100Ah cell price. Or did something change while I wasn't looking?

400Ah x 54 cells will give you close to a 70kW pack. I go out on a limb and say that unless you're dragging a boat anchor or climbing up a wall, you can probably make your 88 mile trip.. twice even. You'll weigh your car down with about 1600 pounds of cells though.

Talking Super 400 Ah LiFePo4 Lithium prismatic battery

Can anyone help me with the least expensive place to purchase 100-400 Ah LiFePo4 Lithium Polymer batteries? I want to purchase a used EV with lead-acid batteries, but don't want to spend like $8,000 on decent batteries. Thanks.
