Razor ground force monster, one of a kind.

- Razor ground force drifter modified for speed and power. 48V Nissan Lead Lithium powerwall 3.5kwh (66Ah) 60A continue discharge, 120A peaks discharge. 48V 2000W 42A motor/45A 24 Fets controller. It has dual throttle, front big LED light, tail light, left/right signal light and brake light. And of course a disc brake. I start with the Razor ground force because I want to keep it small and it turned out perfect for my liking. Its look small but it still heavy due to the battery size and the under body re-enforced with steel bar. Total weight with driver is about 300bls.
The battery advertised as 58.5V fully charged. But I am only gotten 57.2V I think the BMS restricted the battery from further charging. Still pretty darn good at 57.2V. Most 48V battery fully charged at 54.6V.
That thing is by far the best razor build I have seen yet!
Where did you get the wheels
Are you using the stock rear axle from the Ground Force? Interested in the Axle/Wheel Hub/Tire specs. I’m doing a build now and want to add the same racing tires…
How fast does it top out ? I bet if you throw a 72v 3000w motor which is almost the same size but probably would get more torque and top speed
Jordan C. On flat surface road it top out at 41mph with 3:1 gear ratio but weak in torque. Sitting very low blasting at 41mph is getting scary for me because my vision will blur a little bit at that speed and the seat is not a bucket type. Since then I have swap out the 3:1 gear with a 5:1 gear ratio and I absolutely love the new found torque and top speed is reduced to around 35mph, which is just perfect for my liking. You are right is that the 72V 3000w motor is the same size as the 48V 2000w motor. That is an easy swap but the battery are very expensive $800 and its was chosen at the start of the project. Otherwise yeah I would go 3000w for more powerful torque.
@@MichaelGAMING99 Using. straps from walmart, hooked to the rear frame, and around me and the seat gives me piece of mind. i mean to get ratchet straps but got a different type , on sale, rated for 900lbs. as long as the seat stays, ill stay....so far
Can your controller output all 60 amps given by the battery, or is it limited to 45 amps?
I really don't know unless I have a multimeter connecting while it is running to actually see how many amps it is pulling. This controller is a 24 Fets rated @45A. The size of the controller is large and the phase wires/Battery/Ground wires as well. I think this controller might be output more than 45A. Driving over an hrs, the motor got very warm and the controller never get warm. I also have a 48V 18 Fets 60A controller and I never bother to use it. Because by looking at the physical size of it. Its is rather small and the wires guage are about 3x smaller than the 24 Fets 45A controller. My setup is working really well now and have no desired to change anything at this point. I have added a fan to help keep the motor running cool.
I have the same controller as you have, and I have the same kunray kit as yours, only my kit and battery are 60v. Since my battery is very large and gives 60A, I am considering taking a 60A controller, although I also think that the controller we have gives more than 45A.

@@nikolanikolic7808 You say you got a very large battery, exactly what kind it is? Be careful when you out put more volts/amp to the the motor. You will very likely over heat the motor very quickly. My battery is 48V, fully charged is 57.5V. The motor got overheated driving at full throttle for about an hrs and the motor will needs to cool down before you can drive again. Since then, I have installed a fan place over the motor and that helps tremendously to cool the motor down. Base on my experience, I would not bother to run overvolts. Unless your only plan on run for under 30 minutes.
@@MichaelGAMING99 My battery is 60v, full charged 67.2v. 16s 16p lion samsung 35E cell 256 pieces 56ah 3450mvh. my bldc motor is rated at 60v. I hope that I will be able to get the maximum of the engine, since I use an electric scooter
@@nikolanikolic7808 Your earlier post, you said you got the same control/motor kit as mine which is 48V. I would not trust its 60V claimed and you wanting to out more more volts/amps. This assured overheats very quickly. Another note is this, the scooter weight of course plays a big part of overheat, due to the heavy weight and the motor load. Mine is go-kart is about 300bls with driver. If your scooter are weight less, maybe do-able. Here is an example, I got the orange Razor Ground Force Drifter that is setup for 36V 800W motor running with 1000W (controller is tiny) 14ah 48V Lithium battery pack. This combo is a overvolts setup. Running great. The motor never got hot driving about an hrs, going thru the yard grass. Its handle the overvolts well is because the Razor ground force, light weight. The tiny 1000W controller will get very warm. In fact, I have had burned up 2 tiny 1000w controller already. If the 3rd controller get burn out again. I am going to just buy a 48V 1500w brushless motor and use the 48V 60a (controller I mentioned to you in earlier post) So that I will never ever have to worry about burning out controller.
How much to make this monster
A little over $2000. The most expensive part is the battery ($800)
Would you build one for sale?
Maybe. It depends on my dad but is special too and Idk how to make it
@@MichaelGAMING99 let me know what it's worth and I could ship it to him from Hershey pa? If it's worth his time
@@MichaelGAMING99 any luck?
@@michaelm398 Sorry no luck. My dad said no.
@@MichaelGAMING99 want to send the one you have? Lol
Here is new video. Check it out. th-cam.com/video/yhMOLa6B_fU/w-d-xo.html
Hello!! I just wanted to ask you about those two white wires that you mentioned in the comment on the link. They have two wires on my controller and it says "hard boot" on them. Are those two wires? And one more question. I have the same motor as you, only my motor is 60V, controller 45A and I will put a 42ah battery. What do you think will be the maximum top speed on my scooter? th-cam.com/video/4PusroixsGE/w-d-xo.html
Milutin Milutinovic , If you are getting soft start on your controller. Then you need to connect the two white together to activate hard start. If you are not getting hard start. Then why not just try what I mentioned on the link you mention. Now, not all 2000W controller rated the same. Some of them are 2000W but rate only for 33A and only 18 Fets and may or may not have a hard start. The scooter are much lighter than my gokart. You should hit 41mph+ with the right gear ratio. For example, on a flat surface road I top out @41mph with a 3:1 gear ratio. Since then I changed out the 3:1 gear ratio for a 5:1 and I freaking love it. Awesome torque and getting 35mph.
