You don't need contactors to switch signal lines. Simple tiny relays (size of a sugar cube or less) will do that.Cgrcjet said:I got mine from Kelly controller. I searched everywhere and didn't realize they had them. I didn't think I would ever find one that could handle my requirements.

Contactors are used only when switching high current (and/or high voltage) battery-to-controller connections, for main power off / on, emergency shutoff, etc.

This doesn’t mean it’s safe for 150V, used voltage needs to be lowered/derated to cover voltage spikes.
It’s a grey scale, probably a bit over 120V works and 140V don’t.

there are 14 steps for the current setting both in "protection" and "flux weakening" menu. I guess they are settings to 14 rpm steps from zero to max rpm set for the mode that is used. Since my motor is IPM it's tolerant to flux weakening so i'll try to set the steps with higher flux weakening than 50-80A. I guess this setting is for hub motor?
i wonder why 7 should be larger than 6 (apart that more flux weakening is needed at higher speed)?
why no current settings done higher than step 7 in the guide?
what does the "mode" setting do?
What do you think about my guess?
How can I activate Mode 5 on the 72400 controller? Recently I got the latest firmware from a Chinese seller
