Hi peeps, new here, i have a chaos 1600w brushless scooter, 8 months old, my question is i want to replace the god awful lead acid with lithium, sourced my batter but do i need to change controller or will it plug and play, hope someone can shed light on this thanks
 
So, your voltage is 48V (4x12v pb battery - maximul voltage 13,5-13,8V fully charge = 55,2V )
Liion batteries fully charged 4,2V so 55,2/4,2= 13S battery. ( in that case, you will not fry your controller)
but problem is fully discharged PB battery is 11,6V (46,4V) and liions fully discharged 3V/per cell - that is really maximu that do not killing battery for loger use. So 13x3=39V...that is a lot below 46,4 with PB and your controller maybe will not work with that low voltage.
All of theese calculation based on numbers from internet so not 100% accuracy, just for imagination :)
