    The Gen4 maxes at 116.4V or so. 28 lithium ion cells in series is the max youíll want to do. You can pull a max of ~63kW from the battery with one of those. Iíve done that in the past.

    If you use the 82Ah Leafs cells you could get the energy you want at 28s. Or run 4 in parallel of the CMax cells I mentioned and get 100Ah at 28s.

    You may have seen me mention the ME1616 being wound different. I havenít seen anywhere thatís it is specifically offered. I was simply speculating that it could be an option. The sevcon is your best option for cheap and easy, but Iíd love to see someone push the limits of a ME1616

    ...but $1,500.

    I don't have the radiator with this bike (sadly it wasn't part of the deal). I saw somewhere that there are different windings for the ME1616 that can go above 96v. If that's the case, I have enough room for 132v of 64AH nissan Leaf batteries, so I'd just need a controller and the appropriately wound (winded?) ME1616, plus a controller to like a sevcon with a wide enough voltage range to handle the pack. I think the Gen4 goes to 132v but can only handle 50KW. If that ends up being too much of a headache, I'll just stick with the 96v ME1616 and hopefully be able to put a few of the modules in parallel just to increase range. I'll have to read up on it to see if that would be okay or not for the battery health and charging.
    They're a bit more expensive than I'm selling them for I don't think there's a different 1616 anywhere (not that I can find). You're still going to be limited right now to what is available in the market for this motor. I don't know of other offerings of controllers paired to this motor currently.

    I have a surplus of the 116VDC controllers, which is why they're cheaper. The Sevcon's that go over that voltage are harder to get and suppliers like me have to buy in quantity or go direct (and those that do sell those controllers will ask much more for them). Another thing to consider is that once you start going over about 120V, the DC-DC converter, Chargers, Relays, etc, start to get more expensive and harder to find because of the voltage ranges.

    Just mentioning: If you wanted to keep it under 100V, I've got 72V chargers with DC-DC converter inside already (can programmed to finish right around 100V). Then you can parallel more cells together.

    Iím sitting on 90v at the moment, but the ME1003 is only a 72v motor. Not sure how much actual voltage goes into it for Max RPM which is really low at 3050.

    If the 1616 is wound for 96V, and the sevcon can take 116, Iíll aim for 116v of battery. Paralleling controllers is something I know nothing about, maybe itís only for higher voltage stuff (~300v plus?)
    I really think the 1616 will do what I thought I could get out of the me1003 two years ago. Iím mildly content with the performance, so seeing that the 1616 is higher hp and has a much larger RPM (~8000) I think that will work much better for my end goal of being able to cruise at highway speeds without using too much amperage.

    Frodus, Iíll PM you and we can work something out.

    Thanks for all the help everyone! Itís this community that keeps me motivated to design, build and repeat. I have so much more to learn...

    This community is awesome. It's where I started back when there was like 10 people on the forum when I built my bike in 2008ish.

    You can just do 90V if you want, and upgrade to more cells in series later. Do you have a battery charger?

    I cant imagine that you would really NEED to go that high of voltage. This motor is BIG and should be ample power for my purposes anyway. As batteries improve, our packs should get lighter and range will improve... I expect my conversion to be like a fine red wine...just gets better with age!

    Exactly. I started with a brushed Series wound motor and controller and lead acid batteries. Upgraded to Lithium and an AC20 motor.... towards the end though, I got a Brammo Empulse ...hehe.
