Hi Amberwolf, I mean RPM at the motor, just like how the bluetooth one displays it but would be nice to have a dedicated one without needing to hook up the phone all the time. its just a nice to have i suppose. like with cars, i get accustomed to know RPM at the motor at what speed im at.

hi all, is there a standalone RPM display for Far Driver, other than the blue booth one? (dont want to turn on the app/ use bluetooth all the time) Cant seem to find a display for e-motorbike to show RPM for that matter either .. TX

Thanks :D

Just got the Fardriver ND72530, QS motor 4kw and twist throttle handle bundle. controller seem to work fine but its running in reverse. hope the software got a function for this. will try it out soon. wring is simple with the bundle and my 72v20ah (20s) battery but would like to mention you...

thanks everyone for all the replies. <3 :bigthumb: In the end, i think the most simpliest and low cost idea would be a DPST (on on) switch for the user to manually switch between the two packs when one hits LVC while riding. Although i cant seem to find one that would be able to handle the...

45 year old industrial designer here who also lost his job in property development (a troubled industry here) with two kids but still YOLOing trying to pivot into this whole EV revolution. My whole world turned up side down too and it feels surreal. Just try to remember you're not alone. all...

WOW! Thank you :bigthumb: Will dive deeper into what you've written here and below :D So maybe a good BMSs would simply do it. LVC kicks in on the battery that is low SoC and for extra measure a MCU programmed to switch if off

I would need to be judgment proof if the problem of having unequal SoC for 2 parallel battery packs cannot be solved :lol: I actually thought having the 3rd BMS would help mitigate safety risks as it would manage the two packs as one. guess i was wrong. Experienced DC power engineers are...

the problem is that this would eventualy be a retail product and Im trying to develop a more user friendly system whereby the customer wouldnt be concern with needing both packs to be the same SoC

Hey Folks, I have a bike with Kelly KBS 72v controller and a 20s8p battery. I want the option to add on another 20s8p battery in parrallel to add more capacity on some occasions. Each of the batteries would have its own BMS and I was thinking of adding a 3rd one to manage the two packs as I...

Hi Gonzales, fyi am stoked, got the regen braking working. how you referenced the brake light switch got to me but i had to integrate 'normally closed' switch to a throttle of a xiao-mi scooter. cant seem to find an electronic brake lever with switch. Braking power is not strong enough as a...

oic... i never knew they had switches (the one im using now doesnt). will order one asap. gosh thanks again

Progressive regenerative braking. I would like to vary the levels with the brake lever

:( please pardon my confusion. so this means the motor will turn off with brake switch on (as pin13 to 20 is connected), even with Brake Switch disabled in the config software? and i need to a physical switch to get the motor working and need to flip between throttle/regen each time...

but my throttle stops working after i connect pin 13 to ground .. Does this mean I have to connect the throttle switch (pin 15) to ground (pin 20) too? (thereby turning on the throttle switch)
