Hey guys i have a quick question about my electric scooter,
so i purchased a
razor ecosmart metro 36 volt 21amp electric scooter 2 years ago and the battery used to last me about 5miles but now it only lasts about 1 and a half

i was wondering how i could increase the range (and hopefully torque and speed

)
should i replace the batteries with deep cycle batteries or just add a deep cycle battery???
Please make answer as specific as posible,
ALL/ANY HELP IS GREATLY APPRECIATED
