Starting on my first conversion. I am looking to exceed stock power and generally make the machine feel alive.

I have been kicking around the idea of a qs180 90h , with a nd961800. However after looking around the site now I am not sure. I also received a quote for a me1616 with a sevcon controller. The price is quite high, along with the forum posts about low power have me concerned.

Is the qs and the Me1616 in the same power level functionally? The qs is rated way lower, however I see in multiple places folks talking about 50kW with these things, and others talking about the ME1616 only able to hit 36kW with anything below 100V.

The battery I am thinking about would be comprised of 2 of the alfa cells below, wired in series. Would this work, or am I missing something? I assumed I would need to use something like an ANT BMS 400A bms as the factory one would need replaced .





Already have the bike torn down, now just trying to buy all the parts and get to building. Thanks for the help!

sevcon is expensive and hard to program.... you'll be tied to the dealer. Don't recommend it. Buy anything else and program it :)
Those batteries? you'll need to replace the BMS of course and also consider that they are aged.

Don't know much about converting these kinds of vehicles. Hope you get some help here and good luck!
