help with razor pr200 set-up

a likle spaz · #1 03-28-2007

I have an electric razor pr200 and was wondering if anyone could help me with a setup. I've been lookin around and i know you guys are going to ask where i will be riding and stuff. So I won't be racing it... probably just going to ride in the park or somethin. I weigh about 105 pounds. I was hoping to get around 20 to 25mph, but also want more power and acceleration. I have about 150 dollars to spend. If possible i want something that won't require any welding or bracing. All help is appreciated.

well you could get 150amp speed controller for like 100 shipped. This will give you more power throughout the entire powerband as it's 150amp peak and 100amp continous. I just don't know if that little 200watt motor will really show you results. Either way your going to get more power, i just don't know if it would be worth 100 bucks. Those 200watt motors don't draw as much power as the 500watt plus size motors. The increase in power isn't as big as you would see if you were running a bigger motor. The controllers on other scooters running 500watt plus motors are really choking out the power the motor wants to give where as the 200watt motors are comfortable right were they are. You could alway add another battery but then that poor motor will die pretty fast.

A 150amp controller that will only get the 30amps max from the 12volt 7ah gel cells. Hmmmmm? Where is the extra amps you speek of?

if you would like to have fun get this set up:

1) Four(4) 12volt 7amp hour gell cells $15-20 each(you only need to buy two)
2) 50amp 48volt controller $35
3) 48volt fast charger $30-35 (just over 2 hours)
4) 500-700watt 36volt motor $40-45

after shipping it should still be under $150. Get some protection!

Streetz can tell you the best way to mount the motor. To start this build gut the bike! Go to the Electronic parts store and get some power conectors. If you dont have a soldering iron/gun, then get one and some good solder as well!

a likle spaz,

Be safe kid! The bike should top out 22-25mph after this is done. Run time:30min-45min.

Well not really understanding that, but i think our answer is in one of the same. He will see a power increase with just a new controller. Now will that increase be a big one? No! he does't have the powerplant nor the fuel to see it's real benefits. but your idea I don't think is really helping him. He doesn't want to get involved with really modding the bike and or having to fabricate and stuff.

He's going to have to get a different motor and fabricate a mount for it. Hes got to wire up the batteries and the controller with a charger series. I don't have a clue where you found a 48volt fast charger for 30-35 bucks that charges in 2 hours but please share if you have. lol and a 50 amp controller, he's already got a 30amp if i'm not mistaken. That is nothing in the power department while running 48volts. Then there is all the extra weight he's loosing run time. I think his best bet is just gonna be a new controller and maybe a replacement 350 that should bolt right up.

So basically what you're saying I should do is just buy a 350 watt motor and then get a controller with more peak amps. However i was looking to see if i could find a better 24v controller, but the only ones i could find were 30 amp... and that isn't any bigger than the one i have. So where could i get a better controller, and about how many amps should i be looking for in a controller for what i'm trying to do. If i was able to get a 350 watt motor and a 50 amp controller would there be a pretty noticeable amount of speed and power, or should i be looking for a 100 amp controller?

you came up with this great idea that to use hose clamps, good idea by the way! that can get any one to buy a new motor.
also the charger is the Panra 4.5 amp charger..http://www.scooterparts4less.com/web...8v_charger.htmcharges 48v12ah set up in less then 2 hours. Also Amps dont make the bike go faster, it is voltage. Then on the other side of things a 12volt controller would need more amps to get the kind of speed and power a 48volt50amp controller. That 48v50amp controller is the best for the money....

look at a 24-36volt 100amp TSP100 they sell for $130-150 new, it is a very high end solid state low cost controller. I do belive Streetz uses this one in his bike.

The parts list I posted is the best option for you

1) Four(4) 12volt 7amp hour gell cells $15-20 each(you only need to buy two)
2) 50amp 48volt controller $35
3) 48volt fast charger $30-35 (just over 2 hours)
4) 500-700watt 36volt motor $40-45

dude voltage does make the bike go faster....yes you get gold star for the day! but what is he going to do buy new motors every 10 runs.... you can't overvolt these motors like that. He obviously doesn't want to mod the hell out of his bike. Amps do make the bike faster. It makes the bike faster by allowing the motor to rev higher with the given weight. If a motor is rated at 3000rpm's thats a no load rating. Your not going to get that with you weight on it. you'll be 2700rpm maybe. With increase amps your going to get more spin out of it allowing your motor to rev up to 2800 or 2900 rpm. overvolting a motor is cheap speed yes. but not effecient. it's hard on a controller, very hard on a motor and hard on the batteries. its up to him. does he want a reliable bike that runs nice or a dieing setup that will fail when he least expects it. Your setup is topspeed happy but not effecient. your run time dies along with all your electronics.

timetime(exon) you are so clueless... who do you think is supplying them with those chargers... tncscooters has the same ones for 38.00... you know you puzzle me you call this site lame but yet you keep coming back under new names it must not be that lame.... do your research........

streetridaz · #9 03-29-2007

o.k. I get it. 2-4 hour charger is a quick charger to you. Yeah tncscooters have those. A quick charger is under 1 hour from undervolt to peak charge.
these run 400-1000 dollars.

a likle spaz · #10 03-29-2007

So i know i should get the 350 watt motor, but what controller should i get? The only 24 volt controllers i can find are ones that are pretty much the same compared to the one i have already. how many amps would be a good amount? And where can i get one of the better controllers (can't find better 24volt controller on tncscooters).

streetridaz · #11 03-29-2007

the tsp100 is a good controller but only runs 80peak at 24volts. The only one I can find anymore is 150 bucks. They have a 24-36v 150peak amp controller on ev-parts.com that I don't have any experience with but it's only like 90bucks. Might be the deal of the year if it's a good controller.

aproldan · #12 03-29-2007

btw about quick charging a lead acid battery is not a good idea... when you start to quick charge them you run into heat issues problems... when the battery heats up too fast it begins to break down your battery and instead of a 300 recharge cycle.. you start to get less to about 200 cycles... and start destroying you internal cells... bad idea... that is why you shold never go over a 2.0 amp charger... the slower the better for your battery... and for that charger you state putting out over for amps in charge is wrong that one is only 2 amps output... they put 4 to make it look more appealing.... yes people stretch the truth to sell/ explain why their product is costing more.... like i said who do you think is supplying them.......

I was looking at the controller on ev-parts, and it doesn't look like it has the same connectors. So i'm not sure if it will work. I would rather have the tsp100 because it's one that you have had experience with, but i can't find it anywhere.

streetridaz · #15 03-29-2007

I can pm you with it in a minute. You will still have to wire it up. The upgraded controllers won't come wired with plugs/connectors. You will have to splice your wires and either directly wire them to your new controller or cut the connectors from your old controller and rewire them to your new controller.

here's what is see you can use the controller that evparts has, it a 100amp 24/36 volt controller... the good thing about this is you can use it to run on your 24 volt setup and when you decide to put a 36volt system in it or on another project you don't need to buy a new controller because that controller will also work on 36volts... and it's a simply hook up... 2 wires for battery 2wires for motor and 3 small wires for your throttle... and then all you need to wory about is your charger port... all you need to do with that is tie them directly onto you battery wires and your set... not really crazy about the price but for that controller i don't think you're going to get any better then that.......

streetridaz · #17 03-29-2007

Yeah thats the controller I was talking about. Even though I'm not familiar with it, it is a better buy. Tecnically anyway. lol more bang for the buck. Wireing it would be just as easy as the tsp100.

by the way aproldan how did you successfully link something. I haven't been able to get a link to work since i've been back. lol

a likle spaz · #18 03-29-2007

So you're saying i should get the one at evparts because it's a better buy, and if i decide to put another 12volt on the bike it will still work.

you got it buck-a-roo

streetridaz · #20 03-29-2007

well the tsp100 is also 24v-36v but it's 150 bucks now. Aproldan and I were getting them for 95 bucks and that included shipping. The one on ev-parts.com is only like 90 bucks and it peaks at 150 amps. I dont know if thats at 36volts or not but even so it will peak at more then 100amps at 24volts if it peaks at 150 at 36v. I would say its a better buy.
