Re: Motorino XPn Chinese ebike (scooter)

Does a Cycle Analyst show phase amps or battery amps. You tell me. Battery amps only. To see phase amps, you'd have to have a controller that measures those (some do, some don't), *and* a display for that specific controller that also shows you that info (not sure which, if any, do that realtime).

Re: Cycle Analyst PAS sensor with 72v system

From what I've gathered in other threads, I understand that the dc/dc into the CA just gets overworked pulling 72 (really, 84v) down to 10v and can cause it to fail. Pulling up the un/official guide shows that at 84, there's only 10ma and a PAS alone could potentially pull that -- no bueno Basicall...

Re: Adding motor temp sensor to work with sabvoton

The way all of the stuff I've seen so far works, is it has an internal pullup resistor (of unknown value) with it's "top" end to one of the internal power rails (probably 5v), and the bottom end to the signal line of the temperature input (and the MCU). Then the sensor in the motor would b...

Re: Hub motors and were they hide

I have no direct experience, but based on posts here on ES by those that have, it's just another 9C DD hubmotor clone, so is likely to be the same low quality (thus completely typical of ebike motors/etc in general).
