Question (1) is there a difference between the 48 & 60 volt controllers (2) can the LVC on the 60v controller be adjusted so I can run both of my battary pack?
So you still have 60v controllers forsale?
Thanks

hmmm, the 4840 controller,can you tell me what fets you have in there and how many? i believe my 4840 was only 6 fets,although i may be wrong and unless im mistaken the 4840 is 48v40amps correct?ok as for the controllers i have yes,i still have the 60v48amp 18fet controllers irfb 4110 genuine,you cannot run this at 48v as the lvc cuts out at 48v,,,,so unless you are an electronics guy maaayyybbeee and i say maybe because i just dont do mods,you can change the lvc to cuttoff at a lower voltage.but i can tell you this,according to crystalyte it is not advisable to change the volts on these 18fet 48amp controllers,,,,the 35 amps they can and are sending me new 48v-72v 35amp 12 fet 4110 controllers with the lvc only operable at the 48v level,so if you chose to buy one of these you will not have lvc cutoff when using higher volts above the 48v level.so if for example you are using 60v the controller will keep on running to the point of destroying your batteries
so unless your batteries have its own lvc circuit it is not advisable to run anything more than 48v just because of the lvc factor,otherwise these controllers will handle up to 72v without any problems.
