    Sur-Ron Battery upgrade

    I don't want to mislead you, I saw in a screen installation video a warning not to reverse it since it can damage the controller, but now I just found this on google: https://electronics.stackexchange.com/questions/262843/is-it-ok-that-i-accidentally-swapped-tx-and-rx-on-a-uart-bus So hopefully...

    Why 60v batteries aren't labeled as 57.6V(3.6*16) ?

    I wanted to compare two batteries, 60v vs 72v by comparing their Wh, but I noticed that with 72v/20s it's 3.6*20=72v, unlike the 60v>3.6*16=57.6v .. so what's the right way to compare the Wh between 72v/20ah and 60v/20ah batteries, should it be 60v*20ah or 57.6v*20ah?

    ASI BAC 855 peak battery current

    Thanks! but there's conflicting information from their own website(it also says 65A peak in other section) and cyc support claiming it's 90A peak battery current maybe it's only it's a configuration limit that they sell it with? A week ago I emailed ASI about it but received no answer to this day

    I know, that's why I'm asking about the max current of the controller but it's a mystery :D

    Sur-Ron Battery upgrade

    Hi, I have a small question about the 855, The manual specifies 90A peak "phase current", but what is the peak battery current? I need to know the limit so I'll pick a strong enough battery to use it for max settings Thanks

    Is there a difference between a same wattage 48v to 60v motor?

    Will there be a performance/heating/battery consumption difference if I'll upgrade my bldc hub motor from a 1000W 48V to a 1000W 60V, while still using the same 60v battery and 60v controller ? Is there even any structural difference between same wattage motors with different voltages? Thanks...
