    QS 120 2000W phase to phase resistance

    Because I want to heavily abuse :D (meaning, run it a much lower voltage than it's designed for) this motor, I'd love to know the phase to phase resistance of it, to determine if it'll be able to handle the acceleration + uphill power I need from it... Has anybody got one of these, and could...

    QS 90 1kW (edit: or maybe 120 2kW motor) with Kelly KLS controller in a Cityel

    Hi guys, sooou I'm looking at replacing the motor in my Cityel (it's got an old, heavy and super inefficient forklift motor from the 1980s) with a brushless motor. I've put the QS 90 1kw in closer consideration, since it weighs 5kg (which should be enough, and also not to much, iron and copper...

    48V 10.4A 500W PSU Charger Mod, S-500-48

    Hi guys, so a friend gave me this power supply for cheap, and I've been wanting to convert it to be able to use it as an add on charger for my 11s Li-Ion pack. I'm fine with the voltage range (goes down to 41.4 V), so that's okay. The current limits at pretty exactly 18.4 A no matter the...

    Fast charging until 4.2 V and then cutting off

    Hi everyone! So it's well known that when you charge Li batteries to only 4.1 V, you round about double the cycle life at ~90 % capacity ... Does anybody know (or has any experience) on how bad the effect on cycle life is when you instantly cut off at 4.2 V and do not charge until full...
