[@sergionibrue3115]

Good afternoon. Tell me where the motor and controller were ordered. Is it difficult to redo? and what kind of battery do you have?

[@Patrick_Choi]

a.co/d/e8N19Fj If you want to make all the lights and horn like stock , it's very hard to do , because the connectors are higo mini B . If you don't need lights and horn , it's easy. Battery is 48v 25ah 50A

What is the maximum speed it gives?! I'm currently accelerating to 37km/h maximum. I want to drive a maximum of 50 km/h. Another question, where did you order the battery and charger? Thanks

[@Patrick_Choi]

@@sergionibrue3115 Top speed is 35mph , mostly I ride around 30mph feel comfortable. I got my battery from eBay , this kit needs 50A BMS battery

I have two of them .. three years old …. Only problem is the air comes out of the tires every year I fix that by putting tubes inside them and I have a few other modifications that I will be doing…. Excellent job

Yes got mine in a pawn shop just love it and it has paid for it self many times over paid 800 dollars for it want a horn and turn signals but it's all good

Tengo el mismo motor y el patin es casi igual que el tuyo,el mio es el imr evo ultra ya venia con motor 2000w, le cambie el controlador por uno de 50a y bateria 48v 25ah 50ah bms, con el controlador este pilla 61km/h llano cuesta abajo se nota mucho con el de serie

[@thedaydreamer7972]

nice job! Can you clear this up for me? I have 48v 1600w brushless scooter motor in my scooter, stock 48v 12ah 20v LI batt and crap no name controller What is the main component that powers this motor and can push it to the limit, is it the controller or the battery? I was thinking to go with 48v 1500w controller and 48v 20ah 50v LI battery (1800w) max What controller and battery combo will push this motor to the max? I was even thinking of going 60v overall TY

[@JB360_NYC]

Nice upgrades! Out of curiosity, would you happen to know the dimensions of the rear tire? I'm looking to possibly upgrade one with a QS motor.

[@Patrick_Choi]

The rear tire is 145/70-6 , I'm not sure the QS motor can fit

[@mariastigler6005]

Hi, I was wondering if I could just add a controller to the scooter and keep the stock battery, or do I have to add updated battery to suit the controller, also could you please tell me if reduces the battery life or has any problems, thanks.

[@MrKonatar96]

How many miles can you drive on a full charge? Loved the video. Ordering one soon for my razor e300.

[@Patrick_Choi]

In mode 3 you can get around 25 miles and top 35 mph, mode 2 should get 30 miles top 28 mph.

Why do you not show the process of the lithium battery and everything step by step

[@Patrick_Choi]

I'm not a professional electrician ,so I didn't plan to make a modifications video. The battery swapped was done a year ago and just a easy job, but I took whole day to do rewiring , another day to installing the kit.

Possible to put a thicker chain 8mm

Where did you find/ordered the lithium ion battery of 50 amps? I ordered the same kit of Kunray but I have the wrong battery. It can't deliver that much current.

Patrick, please explain how you use lithium battery. They use lead acid yes? Thanks

[@Patrick_Choi]

Stock lead acid battery weight 36lbs vs 15lbs , lithium battery can deliver efficient performance at power as low as 20% , the size smaller and more range. My new 45A controller is huge can't fit in stock battery.

[@mohamedalaoudi8018]

I want to buy two

[@MichaelGAMING99]

The kit in default is a soft start mean lag throttle. You must connect the 2 white wires together to get hard start. Your battery only capable of deliver about 30A continue. Do you want to go faster? get a battery that is capable of deliver 60A continue will get you over 41mph. I got the same kit and total weight of 300bls. Top out 41mph. You can hear my motor run a lot harder then your. Simply put because I got a much more powerful battery. Check out the video here. kzbin.info/www/bejne/eJnVgI2LeraqbrM

[@Patrick_Choi]

My controller doesn't have hard start function, the seller said I have to buy another hard start controller and my battery is 50A continuous 150A peak , because my tires size is 14.5 off-road tires so it seems less power than yours. I tried different sprocket can get higher top speed but not enough torque for San Francisco hilly road. Thank you for your comment , you got a nice go kart!

[@milutinmilutinovic4393]

In that case there is no risk of a burned out engine ???

[@Patrick_Choi]

@@milutinmilutinovic4393 I've been riding it for few months , it still runs good .

I have the same kind of engine, only mine is 60V. The controller is 45A. I'll put a 42ah battery. My rear sprocket will be 44 teeth and my front sprocket 15 teeth. How fast do you think my scooter should reach?The two wires you mentioned in the previous comments are the two white wires that say "hard boot"?

[@Patrick_Choi]

@@milutinmilutinovic4393 With 60v battery , you can try different front sprocket (cheaper) , bigger front sprocket get higher top speed . I think it should be get 40+ mph , depend on you want more torque or higher top speed.

I watched the video well. I am going to upgrade by purchasing a 2000w motor and controller. Do you have to install the switch 1.2.3 (throlt) as well? Do I just need to replace the motor and controller from the basics?

[@Patrick_Choi]

My upgrade kit needs to install the switch , without the switch you can't get the full power , some people just bypass the wires but I'm not sure . Sometimes I need to turn down the power at busy area, so I suggest you install the switch.

[@Patrick_Choi]

I would suggest you buy the hard start controller instead of slow start controller , huge difference.
