I just finished this e200 that I found on the curb. I put a 350w hub motor on the front and omg its quiet and torquey. I'm running a 1000w LSD149 controller. I hit 21mph on it yesterday with 1 single hoverboard battery at an 80% charge. I'm going home today to try two Batts and see what it gets me. These scooters are a blasttttt

[@brianyambao274]

Thank you for breaking thing down... I’ll reach out soon enough once I start my mods. I just recently purchased an E300 and stock motor and battery is crap. This has been keeping me up for days since I want to make sure that I get the right parts for the mods. Plan on using this as a daily commuter so I’m lookin more for a good ave rage speed, reliability of parts and battery power.

[@grandtheftauto1233]

Tim you know I love putting more amps into my motor then it likes! ;) great video! For the battery recommendation I can say that finding a reputable company who uses Samsung 18650s in their packs would be good. They’re searchable by their configuration such as 10s3p meaning 10S (10 cells in series to make 36v) 3P (3 parallel for capacity in AmpHours). These have BMS integrated and PVC wrap just as the hoverboard batteries. Charger cooling is a great idea. Keep up the great videos!

[@ivanmukmin8952]

Thank you very much Tim, really good information you give for people like me that want to get and mod their first scooter...cheerss..

[@defenderdave4931]

Great video, I accept I'm a bit behind with scooters ,appreciate the clear descriptions and how to and ,what not to do upgrades.

[@jacobpope11]

Great video and information. Did you end up upgrading the throttle to a variable speed one? If so which one?

[@ashleyread6385]

If I change the battery to a hoverboard battery because iv got one can I use the same controller and just change throttle

[@CSJiGSaW08]

If I want to keep the system 24v LifeP04 batteries with 2 x12v. How many amps is the 24v motor 250w versus 350w 24v for non hill climbing. I will puts 44 teeth rear sprockets and 11 teeth motor. I’m concerned about range/battery capacity and top speed. Torque is not an issue unless it’s stop and go at intersections in the sidewalk. Does gear changing affect the amps or is it the motor change?

[@TheCaffeineRacer]

The key is to get the gearing to a point were there is good torque to pull you and handle terrain. But not too much that your top speed is badly effected. I have never changed my gearing. I weigh 74kg. Remember you are asking the motor and to do things it's no designed for. What's the serial number for the motor you have. Will find the a page

Hi, I have purchased a 36 volt over volt kit for my 2014 standard E300. I have also got two 36 volt 4.4ah batteries wired on XT60 plugs to one XT60. Are the any other plugs that I need to upgrade. The kit comes with a key and display but the wiring colours don't match up. Could you supply me with a diagram so can ensure that nothing goes wrong. Are there any other plugs that should be upgraded?

[@glennbreukelman8241]

how far does it go martyn benny?

[@FrugalRepair]

Thanks for all of the info. For the 500W 24v motor that you ended up with, why not get the 36v 500W config so that you are not over-volting? Is it because it does not natively fit in the E300? I picked up an e300 with no motor or control board and the higher torque for hills seems like a better choice than the higher RPMs for speed.

[@TheCaffeineRacer]

Must admit I never found a 36v version when I was looking wats it's top rpm?

[@FrugalRepair]

@@TheCaffeineRacer From an ebay listing: 1) 36v 350w 2650-2950RPM ≥1.12N.m 12.6A 2) 36v 500w 2400-2650RPM ≥1.79N.m 18A . With these specs, would you still get the 36v 350W?

[@TheCaffeineRacer]

@@FrugalRepair I will always go for the highest amp rating my 500w can take 28amp. So it never feels stressed or hot. These sound interesting and worth a test may be. Maybe you can send me the ebay listing numbers If you wanna chat on this subject [e-mail]

[@damiandragon7337]

Hi, I just got a Lithium Li-ion Battery Replacement on the way do you video to show how you set everything up

[@gavinriby7282]

Hi mate most of your links are down but I was wondering where you get your batteries from. Also I need a 500w motor as I am I big bloke and the stock 250w is useless but maybe the battery is dead on my £20 Razor e300. I was going to go for a twist throttle and upgraded battery controller... Is there any need for the controller when over volting to 36v..... Seriously new at batteries and electronics I haven't got a scooby doo... Cheers

[@Kevin-we7ne]

Everything you said was so helpful thank you.

[@Kevin-we7ne]

Hey, what happened with the 500 watt motor, how many batteries did you use two or three. I have an electric scooter razor e325 that I would like to upgrade your ideas are giving me ideas and direction in which I want to head with my built

[@TheCaffeineRacer]

@@Kevin-we7ne I am still testing it. Only put this videos together yesterday I haven't tested it throughly all I know so far is the 2 batter 350w motor set up is the fastest and most fun to ride

[@grandtheftauto1233]

Kevin Affoon I would recommend the 500w motor Tim talks about in his video. The 36v set up is very capable with this motor and fits very good with the power output. When I drive long times at reasonable speed (15-20mph) I can get very good range and don’t have overheating motor issues. I am a little crazier of a setup than Tim’s here (big battery 48v and 1kw controller) but the same motor and also I got the e325s haha highly recommend!!!

[@AhmedKhan-ei2qh]

Hello tim, I was thinking of wiring two of the hoverboard batteries you were talking about but is there any way you could show how to wire the batteries so that it only registers as 36 v and not 72v

[@TheCaffeineRacer]

In my build video i show this I believe you just need to make or buy a parralel cable here is a link to one I will make a video on it today for you. Simply From the batteries connect both batteries positives to one down to one positive connection. then the same with the negatives. Then u will have one connection from battery to connect to your esc and will be 36v not 72v :) www.ebay.co.uk/itm/252825050866

[@ashleyread6385]

Oh it's 36v battery BTW will the standard controller work with it or do I need a new one

[@fraserm803]

Hey Tim.... like your style m8 and have copied alot of what you have done.can you update us on when you were running 36volt batteries (2 of them) on the original 24v 250w motor....did they burn out eventually???

[@jasoncoleman2104]

You should go hub motor next I have a 800w brushless setup on my e300 but this hub motor is just amazing

[@TheCaffeineRacer]

I have a an outrunner for my next project and have just printed the disc rota conversion parts for the e300 I am gonna sell a kitt that bolts straight on soon

[@TheCaffeineRacer]

E200 sound great do a quick video and post me a link

[@Kevin-we7ne]

Got any pictures you can send, I originally wanted to do a hub motor but all I found was small tires

[@TheCaffeineRacer]

@@Kevin-we7ne cant send pic on here sadly will name a video when done

[@TheJollyroger6707]

@@TheCaffeineRacer did you get a kit together?

[@stewartfenton2531]

Great videos. Quick question what hoverboard batteries do you recommend from E bay?

[@TheCaffeineRacer]

There are no guarantees sadly on what u might get don't go cheap as they will be awful and some are fake. I had one that was 20 percent fake cells once. They were even connected. 40 to 60 £ a pack is about right. But pandemic has slow production shipping and increase prices sadly

[@Abdul_-ct6pn]

Hey tim sorry I’m I’m bothering you with these questions but, I’m currently trying to find ways to upgrade my e300 scooter and I found your video really useful, I have a question if you were to get a hoverboard battery and put two in a parallel circuit, wouldn’t you have to get a 72v controller

[@TheCaffeineRacer]

Nope parralel circuit will give up 36v with 3x the capacity. A series contion would give u 72v and would fry your 24v motor instantly.

[@ryujiyamazaki583]

Hi, thanx for the great information and the video that you have made but I have a question and that is that I have a 350Watt Motor, what controller should I use as I am getting confused with it. I appreciate your help, thank you 😊

[@mapquestHs]

I would run a 1000watt 36v controller

[@Abdul_-ct6pn]

Hey tim, I upgraded my motor to a 300 w from 250 w and I upgraded the speed controller to 24v 500 w controller and if I was to upgrade to a 36 v lithium cells could I constantly go at full throttle or would I burn out the motor

[@TheCaffeineRacer]

u need to know the max amps for your motor then how many batteries you are running and what amperage they are. the size of the controller wont matter to the motor. just means ur esc can handle upto 500w ur motor will only draw max 300w so no issue there.

[@Abdul_-ct6pn]

Timsalsanights aka The Caffeine Racer okay thanks mate

[@mapquestHs]

Only problem I see is putting 36v to a 24v controller.

Hi I baught a razor e300 a number of years ago as a child I am am now older and larger I am tall and large framed ,and I am looking at modifying my scooter as I need an option for a daily commute to college and was just wondering what would be best for me another downfall is that I live in a verry steep area.

[@angstfree2008]

Tim....similar batteries and 350 watt motor. Going from 2 batteries to 3 batteries on the 350. Should I be concerned about the 350 watt motor burning out? Also, can you show the configuration of the 3 batteries on the E300? Also, advice on scoring heat sink? thinking of adding...

Can you charge the 2x hoverboard batteries from the charging port of your e300?

[@TheCaffeineRacer]

I charge all 3 yep

[@leanrambles7468]

@@TheCaffeineRacer thanks I actually found your other video where you talk through it. Instead of changing pin on charger is it not possible to just buy charger w correct one?

[@anthonylawler3239]

What was the controller and throttle u upgraded to

[@Abdul_-ct6pn]

I’m kinda new to the electrics and which battery is the best but if I got the 36 v lithium 18650 4.4 ah doesn’t that mean it would run out quicker as it has less ah

[@TheCaffeineRacer]

4.4ah is standard for hoverbpard battery if they say they hold more most will be lying stock is few and far between at the mo obviously dont by cheap wait for the good stock to come back. have 2 batteries and you will have 8.8ah booom

[@Abdul_-ct6pn]

Timsalsanights aka The Caffeine Racer wouldn’t that mean I would have to get a 72 v speed controller if I was to wire two hoverboard batteries ?

[@leanrambles7468]

Can you update links?

sad to say but most products listed are now not available from these suppliers but it gives you an idea what to search for
