Thanks mate, It's still running now, has 1600 miles on the clock, l built a second ebike so this one is my back up bike now. My new bike is the same kit with a 52v 20ah battery, top speed 38mph. The voilamart 1000w kit has been very reliable for me.
@@EbikeRyder heya. my kt15ah controller says its rated for 36-48 volts. I currently have a 36v 15ah battery paired with it, with a 250watt motor. Im getting just over 20 mph when i ride. Which isnt bad. But i want to try and push it closer to 30mph. So my question is could i replace my battery with a 48v 15ah battery instead to boost speed? And will it safely do so without the risk of fire or overheating? I mean i would assume so, seeing as the controller states on it thats its rated for 36 to 48v. But i just want to be sure. And roughly how much more speed can i expect to get?
When I changed from 36v to 48v battery the top speed changed from 23mph to 33mph on the same controller and motor so I imagine you would get similar results of around 10mph increase.
Hi I when I try this I can only go slowly or if I push the throttle too much I get error 006 low voltage ??, and when I don't sit on the bike and use the motor it goes 30mph, it doesn't make sens
This sounds like either your connection between your battery and controller box has a problem or your battery is not powerful enough. When I was using a 36v battery it was 30mph maximum. I now use a 1000w motor with a 1500w controller box and a 52v battery and get 38mph. Just make sure you match your replacement controller with your kit if you do this.

Yes if it's rated to 48v it should be fine although to switch voltage on my bikes I have to change the settings in the display menu, I think you'll be able to anyway without changing settings. On a 250w motor you will gain speed but not loads even at 48v, I'd guess 26-28mph max. If you can afford to I'd suggest a self build from kit, they're easy to fit and you can choose motor wattage, what controller box to use and it's easy and cheap to upgrade.
@@EbikeRyder thanks for the quick reply. Yeah i saw in other comments you saying that you can switch between voltage settings on your lcd. Im not aware that i can do that with this kt controller. I always assumed that it would just automatically know what to do depending on which battery i put in, and just work smoothly from there. Good to know that it wont start a fire though. Thats literally my worst fear. To be honest 28mph would be great. I mainly use the bike for commuting and deliveries. Just want to be able to keep up with traffic easier. I think if i ever built a bike that could do 30-40mph+ on public roads i’d just get way too carried away with myself and let the adrenaline rush get to my head and end up hurting myself… though i am looking to build a bike strictly for offroad purposes at some point though. This one will be built for sheer speed. No doubt. Thanks again.
@@Kumari_44 I'm sure if you plug a 48v battery in it will work fine if your controller is 36/48v capable the controller should just recognise it. Good luck with the future build mate, I'd recommend the voilamart 1500w or 1000w kit with sw900 display (£260), a 52v battery for all around good fast and easily upgradable bike.
@@EbikeRyder thats great to know. No burning house 😌thanks again for the help. Really appreciate it bro. And thanks for the recommendation on the kit too. I’ll look it up. Deffo Super excited for the build.
@@EbikeRyder That's really interesting. I bought a s830 display with a 500w controller im about to try it out. Its from ebikeling. Do ya have any tips/tricks on using it? Thanks!
I've just checked the S830 out ,it's an earlier version of mine but the settings menu (P01-P16) is identical to mine. P13 was the setting I got wrong. My motor contains 46 magnets I had it set to 8. You press the up and down arrows together to access the menu, and then use the M button to select function. Hope it all goes well.
@@EbikeRyder I just tried it and I was not happy with the way the pedal assist operated it was laggy. The speedometer was so off too. I may as well go back to the original display. Its a flying shame
Hi I bought this kit from ebay, it was around £250. It came with the motor, controller box, PAS system, LCD display, motor cutoff brakes and a twist throttle.
I guess controller is the key... some 48v won't work on 36v... only for a little if 36v battery is fully charged... that is about 42v and 48v battery cuts off at 41v... so you have 1v range 🤣
Yes the controller and the LCD display are vital to change between different voltages. The settings in the controller can be changed through the LCD display settings, between 36v and 72v but some controllers won't support past 52v.
Yes Zia it is normal, I used a 36v battery at first and only got around 23-25 mph maximum speed, I would highly recommend an upgrade to 48v battery, it makes a big difference.
Mine was 30 kg fat bike. 48v 1000watt hub motor with 48v 40ah lithium ion battery. Speed i get is nearly 45-50. My routine road is smooth. So I am easily speed up my bike. My weight is 65. I selected heavyweight cycle. So weight is biggest draw back for ebikes. But I love looks over range😂😂
Hi Paul rider can you help me is it ok if I have a 36v 350w hub motor and I switch it with a 36v 1000w hub motor and then can you tell me what the top speed will be on my 36v 350w it goes 15.5mph
Hi when I was using a 36v battery with the 1000w motor the top speed was between 23mph and 26mph. I don't know if you have an lcd display for your bike but I had to change the settings on the display to 36v to use a 36v battery, all 1000w motors are set to 48v by default and the only way to change it is with the LCD display.
I'm not familiar with your bike but I've googled it, from what I can tell it's a 12 inch wheel rear hub motor. I know you can buy 12 inch wheels for scooters that can go as high as 2000w but don't know if it would fit your bike. If you type in Google "12 inch wheel motor" it'll give you some to look at, maybe if they give the axle measurements you can compare to the bikes measurements. Hope this helps.
Also you would probably have to upgrade the controller box, to take higher voltage and replace the battery to a higher voltage one to run a more powerful motor. It would be cheaper and easier to buy a second hand, self built from kit, ebike to be honest.
It depends on the ah (amp hours) of the battery, my 36v battery is only 7.5ah so only about 10 miles. My 48v 20ah battery can get over 20 miles without pedalling.
It should work ok, I'm using a 52v controller with a 48v motor and a 52v battery. They work so in theory yours should too. Hope this helps. P.s. thanks for the sub
I subscribbed and ask question in other guys out there but they ignore my message ..but you sir respond to my comment quickly im so glad and learn new lesson.more subs to come
i purchase 48v 750w bafang motor but i purchase battery separately. the battery that i receive is rated 36v 20ah. can i possibly pair it with my 48v 750w motor?
If you have an LCD display with access to settings for the controller then you can switch between 36v or 48v. If you can't access the controller settings then it will just think your 36v is a depleted 48v battery. On my kit I can switch 36/48/52v on my display.
@@elahwentv8086 no with undervoltage it would be safe, but you will lose 20% performance from the bike. Going over the recommended voltage without changing settings would be dangerous.
Hi yes if the controller is 48v and the motor is 1000w and the battery is 48v then you should get the same speeds as me in theory, that's exactly what I'm running.
Also if you have an LCD display you can access settings to change the input battery voltage between 36v, 48v and 52v. So you can use the same controller with all 3 battery voltages.
@@EbikeRyder Okay hold up. So my 36v rear hub motor won’t burn out? What I I tried using a 48v 1000w BATTERY with a 36v CONTROLLER? I read online that it could potential burn out the controller cause of too much energy. I’m just a little nervous to try it with my 48v battery cause it could cause irreversible damage to the battery.
@@ripp3rjak934 Don't try it with a 36v controller box unless, like mine, yours is changeable through the LCD display settings between 36v, 48v and 52v. Never just plug a 48v battery into a 36v controller unless the controller settings have been changed to 48v first, that would probably destroy the controller.
Hi Victor, I'm not 100% but think the controller is 30A but don't have specifics. If you are getting 1000w or above, it's important you get the LCD display with it if you want to use a 36v battery so you can access the settings to change. I was getting around 8 miles, using throttle only with 36v 7.5ah battery.
@@moisestorres9618 hi yes its easy as long as you buy the lcd display with the kit, there are 16 settings you can access on the lcd display one of which allows to switch between 36v 48v 52v. Otherwise if you plug a 36v battery in, the controller will think it's a run down 48v.
Hi if you have access to the settings through the LCD display then you can change the battery voltage to 36v and it will be fine, but if you just plug a 36v battery in and its expecting 48v, then it will think it's a depleted 48v battery and cut off straight away.
@@endurmesure9442 yes mate, mine was £250 from Ebay with 1000w rear hub motor , controller box, lcd display, twist throttle, brakes with motor cutoff and pedal assist sensor system.
@@endurmesure9442 not far to be honest mate probably 7 -10 miles using throttle only. When I first built mine I was using a 36v 7.5ah battery and the furthest I went was 7.1 miles but didn't push it until it died.
This is my old bike, it topped out at around 23mph with the 36v battery but had no power for hills.it got 33mph with a 48v battery. I'm now running a 1000w motor with 1500w controller and 52v battery, now I get 38mph and 25mph up steep hills.
I can use a 36v battery with my 48v kit because there is a setting on the LCD display to change the battery voltage between 24v,36v,48v,60v and 72v. I'm now currently using a 52v battery with the display set to 48v. My top speed is now 38mph with 52v.
@@younessghir yes this is too much power for the 750w controller and will probably burn it out or burn out the motor. I upgraded my controller box to 1500w with 1000w motor so it could take 52v battery, the 1000w 48v controller couldn't handle 52v. I don't think you will get more than 28mph from a 750w motor no matter what voltage the battery is.
@@rjbikes1237 there are some 48v 10ah batteries available on Amazon and eBay for around £150 ($175), I think that would be the cheapest that I know of. If you don't mind mind using sites like AliExpress you might find one cheaper.

Only if the controller box is capable of taking the extra voltage. If it was a pre-built bike it probably won't be able to.

I upgraded my controller box to 1500w with 1000w motor so it could take 52v battery, the 1000w 48v controller couldn't handle 52v. I don't think you will get more than 28mph from a 750w motor no matter what voltage the battery is.
would a 36 v battery work on the 1500 kit?
I don't think so, I think 1500w motors will only work between 48v and 72v.
@@EbikeRyder ok would you know of any cheap 48 v batteries
@@rjbikes1237 there are some 48v 10ah batteries available on Amazon and eBay for around £150 ($175), I think that would be the cheapest that I know of. If you don't mind mind using sites like AliExpress you might find one cheaper.
@@EbikeRyder thank you very much
lol 62 mph, doubt :)
Lol, I know unfortunately I had the magnet settings wrong and it thought I was doing 62 when it was doing 10mph. Added loads of false miles on the odometer too.
@@EbikeRyder look on the bright side, at least the police didn't use a meter like that :)
@@dsfghzxc6604 my later videos have the Speedo working properly, tops out at 37mph.
@@EbikeRyder That's incorrect
@@ianmangham4570 what's incorrect?
Pff......😐
