Yeah, the 12.44 is what’s back in there now. ---

Just bought a 2007 E6 and wanting to go Lithium and AC! Do you guys still build packages? ---

Ok good deal! Have been trying to buy a complete package but no luck! Ready to buy yesterday haha! What kind of range and mph can I expect? ---

That is sort of a loaded question without an exact answer. The big grey area is your e6 full of adults. Speed, performance and range are all inversely related and connected to your foot and that “Oh Baby” area of your brain that just don’t care. ---

Average Gem, average speed, ~30 miles range. High speed, stop and go, heavy load, easily 1/2 that. Ac motor, can be much more efficient if programmed for slow starts and limited speed. It all comes down to try it and see. Battery is refundable if you need a bigger one. Or the second one can be discounted to double range. ---

What’d you decide? The e6 with 8kw AC motor would be killer. One of these days, I’d like to build one. ---

He has the info, his car is enroute to him now. As soon as it arrives we are going to take a closer look at the gears and put sone final numbers to it. I have already done an 08’ here in KC - but now it has a 25s Tesla battery in it. We cut a hole in the back and middle seats to slide the 6ft long battery in. 🙂 > [@Newly Converted E6 - AC motor](https://community.electricforum.com/t/newly-converted-e6-ac-motor/19110): > > Here is a brand new AC conversion we just completed on a 2008 E6.
