hi 1boris,

most Chinese suppliers are easy going - if you want an extra label, they'll print it and only charge you for the label, not what's on it. After all, that is your responsibility, it does not have their name on it.
Regarding the word 'nominal' - most Chinese people you talk to at sellers in aliexpress don't understand it and don't see what the fuss is about.
By the way, it's up to the bike manufacturers to specify nominal power, not the motor manufacturers.

Just to pick up one point from that. The Q128 is rated at 500w, but it has nowhere near the pulling power of the 350w BPM or CST. It might be better at 48v. I didn't try that, but I went as high as 30 amps at 36v and it still couldn't climb our 14% test hill with 100kg on board.

Hit and run thread by 1boris, a BMS Battery employee methinks.
