E-bike Controllers - ASK Anything - Interview with a leading controller company

[AHicks]

You don't have to but KM5s (original King Meter) protocol has limitations.

BTW third-party displays CAN be used. If you can get past the product coming from the CA3 developer?
See Grin 9 pins connector adapter and other available options.
9 pins adapter has pads for the Tx and Rx communication signaling when using 3rd party displays that operate with the KM5s protocol.

All due respect, but personally, not interested in getting into this here Tom. Much more interested in the learning more about the controller being discussed. The displays they will have available is a good point though.... -Al

Oh FFS Grin are ASI. But whatever…

I think you will really like the Part-2 because we delve deeply into controller programming.

What I find exciting is having a vendor use them and have a group of experts, and scientists tune the controller so well that a majority of end users don't need to make adjustments, and if something needs adjustment to have the sort of guidance your group can provide. WELL DONE! It's a complex device for a kit builder.

Will it be completely potted in your application? Battery based?

I have recently purchased a class 3 bike. It's not giving the speed I'd like so exploring options. The manual for the display states
"KMSS protocol limited speed adjustment scope is 12-40km/h; Lithium Battery No. 2 protocol limitied speed adjustmen scope is 16-64km/h."
Mine is more inline with 40km/h top speed. From this can I gather that there are two types of protocol; kmss and Lithium Battery No.2? It seems the protocol is in the very fancy display. If I change the display to a Lithium Battery No. 2 type should that unleash the potential of 64km/h?
The bike is Luckeep X2 with display integrated into handle bar stem.

Here is what I've found for a lithium battery no. 2 protocol display. Again I'm assuming this is what controls speed so long as it doesn't burn up the controller box buried in the bike though I believe the controller box in the bike will still limit a max 25A output on this 48v bike that comes with a 20Ah battery of samsung cells.

Can you shed light on this?
