Long time no posting, sorry guys.
Took her for a spin last night - first time actually after upping the programmed power settings to about 6kW and half a charge (see below):
Not too happy, though - accelleration in first gear is nice, getting peaks of about 5.5kW but quickly tapering off as the rev limit is reached (~35km/h in 1st), 2nd trying to pull the same power usually leads to controller shutdown (back on throttle release)...
In the meantime I worked on soldering the 24s Zephyr and wrestled with my Menwell USP-500s. Lesson to be had here: Do not use power supplies to charge a battery pack without additional current limiter
(like Fechter's board - many thanks for that BTW, built it on perfboard).
2nd replacement PSU is on the way...
Also finished mounting the IKEA hinge for the now fake tank cover:
Minor mods on the plate where the thermostat etc. were mounted:
(in the meantime the wood has been replaced with a larger PE plate, IKEA Legitim FTW
some pics from the drivetrain after my first commute. Probably oversped the motor by downshifting, but some Loctite won't hurt on the little bolts on the Alien can either. Replaced with the Turnigy's can (where this wasn't an issue, even with 90V@kV130) for now, added two 12V fans, too, for good measure.
The belt pulley is entirely my fault - too much pressure on the rim when taking it off repeatedly during all the testing. How it ended up THAT mangled is a mystery, though. Still able to use the pulley on the 2nd motor, once I get to that.
(Note: white cable is from a cheap fridge type digital thermometer.)
