I need more torque and hope to buy a 48V Ping an' just plug it in and ride. Yet I've lost info on my controller, the sticker fell off and it's just a little black box, not much bigger than a pack of cigarettes. I know it's rated 35 amp for a brushed motor only. No problems presently running the 37V Lith-ion battery. I recall the LVC lo-voltage-cutoff is 29V. Ya' think it'll handle the 48V 10amp hr Ping? I only run the battery to cutoff occassionally, and generally cruise 18mph/90% throttle (probably 19-20mph/80% with 48V) to match my high gear and 80 rpm cadence. Will it stress the Ping 48V to run it down to 29V? All opinions appreciated.
