My 45 Amp controller can take 80+ volts. Do you think it has a shunt like that I could mod ? ? It's maybe 5 years old, didn't come with any displays. Runs my diy disability scooter up to 37 mph at 80 volts using a 350 watt 36 volt direct drive 16" hub wheel

[@colinwhite144]

The best Controller for that shunt is 35+2amp on 52v17.5 battery and 35amp fuse use 30amp it blows it does improve torgue power slightly but its good upgrade. If you have 2000 wat bike 45amp lcd sw900 set at 100 speed 52mph you can actually do a shunt on a 45amp controller and definitely get more power but up grade battery it draws a load of amps 72volt battery or I uased green wick drill battery with built in BMS 5v7amp 12batterys so if one goes fa it's a case of putting one battery in instead of buying full battery it works out much more cheaper

Shunt mod, cool man! I would also tell people to discharge the caps with a flathead screwdriver first before messing around too much inside the controller housing. I recently opened a tiny 48V controller to diagnose it and when I discharged the capacitors it let out a seriously massive spark, that wouldn't be fun to touch 👍

[@E-bikeguy]

Thanks bro you made a good point with the capacitors, for some reason I touched the back by accident too and didn't even think about touching the battery wires together to discharged them , they do give out a loud spark lol even when you connect battery with anti spark xt90 still spark, I know on a 72v battery .

[@sleepingbearffg5008]

Great advice..

good stuff! was wondering, are controllers and batteries pretty much universal ? or do you need to match the same brands ? controller & bike brand for example

[@E-bikeguy]

You can mix and match but most importantly you have to make sure the battery is compatible to the controller, like if the battery can handle the current the controller is asking for

[@imho7250]

Im tempted to try this on my 13a controller the size of a pack of cigarettes but I would have to calculate the shunt resistance i need to make it 20a max, not 40a, because my BMS is 15a with a 30a fuse. I would go into the upgrade death spiral because i need a stronger BMS to supply the shunt mod controller. Lately every repair/upgrade i do causes something else to break. Lol

[@hank_Reardon]

like the intro and music as well as picture overlay! watching your video made me notice my controller had 100v on those things. I currently have a 52v battery, does this mean if I bought another battery and wired them in series the controller could take it?

[@E-bikeguy]

Yes it will at full charge my battery is at 67v and the caps is at 63v when I connect the battery to the controller I thought I was going to hear a pop but nothing happened so we turned it on and off we went lol

@@E-bikeguy i ordered the 5000w kit, but ive got a 2000kw kit with a small triangle, might be worth doubling up the batteries and see what happens. if it doesn't work just send battery back.

[@E-bikeguy]

Ok keep me posted

[@imho7250]

@@hank_Reardon , if you are saying you bought a 14s Li-ion pack (52v) and want to buy another to put in series 28s, 104v nominal, 118v fully charged, then you will definitely fry everything, the controller, the display, and accessories that are wired off battery power. 63v caps are for 48v nominal. 80v caps aee for 60v nominal. 100v caps are for 72v nominal. You can get away with 63v capacitor for a 60v Li-ion (67v peak charge) if you are lucky, eventually it will pop if the charger is left connected after the light turns green (as it should be occasionally to balance the cells). The other big problem is charging them, you will need to plug in two 18s li-ion chargers (or charge one then the other, taking twice as long). If you bought a kit with a controller, display, (dc/dc converter optional), you need to see what the supported voltage is. Many controllers and displays allow you to select 48v/60v/72v but if you plug in 117v, you will need a new display and controller. So if you didn’t get what you ordered you will be better off using the return policy (unless you need to pay shipping to China) and get what you want, 5000w motor, 72200 (72v controller), and 72v battery (or two side-by-side connected in parallel not in series). Even with that you might sill need to open then and upgrade them from 60a to 100a each. If you use just one battery you see what EbikeLife had to do to make it capable of bursts of 200a. The Chinese assembles the cells wrong so he had to bridge over the single strip series connectors because they are only good for 30a, at 60a they were getting hot, at 100a they were smoldering, and 200a they burn in half.

[@hank_Reardon]

@@imho7250 Thanks for info, I'll hold off on that then. @IMHO Thanks for info, I'll hold off on that then. What if I buy 96v controller? Think 2000w can handle that voltage if I put statorade in the hub to keep it from overheating?

[@UrDadsFavouriteMaleEscort]

I have no idea what im doing, figured id ask, how would you recommend upgrading a freego f2 pro for more torque? Im a bit of a hazard during takeoff from lights in traffic. Under the "battery" section of their bike specs it claims to be 48 volts, 22.5 amp hours, 1080 watt hours. I assume the battery is where the watt hour measurements come from. So the speed controller would be where the amp hour measurement comes from? The hub motor says 1400 watt peak, uncertain of its nominal rating. What would you recommend doing for my desired purpose? And what should i be concerned about in terms of "hardware clash"?

I would say power level 3 till you get a battery to handle the current but long as the bms is not going into protection mode, but if you battery is at a 100% and you have a voltage sag then might be a problem with the battery's capacity

[@burningneedles]

Does the “more power” include torque and speed? Mine is a 1500w and I usually top it at 33-35 how fast do you think it will go if I shunt my controller?

I just bought a juiced bike ripcurrent and it has a 25 amp controller. Would it be safe to do this mod? I don't want to fry it because it takes a special controller and I don't think they're in stock. I know it will void the warranty but that's not a big deal to me as I can do the repairs but it's getting the parts. You can't just use any controller because of the torque sensor they use on juiced bikes. I have a phaserunner controller but it's not compatible with the torque sensor I don't think. I'm still doing research. I sent grin tech an email but haven't got a response yet. Thanks for any help you can give me.

[@E-bikeguy]

Yes the sunt mod will help definitely in power and you would fry it. When you open the controller up make sure you see the sunts should be located in the back of the controller. And just solder them together but if you can locate them. Then the mod might be the best solution. But most low end controllers or mid range should them. You will be 50 amps then

can existing 20amp 48v controller handle upgraded battery of 48v 60ah lithium ion battery? will controller get smoked or function without issues?

No, it will be fine the battery can supply the controller with plenty of power the controller can only pull what it's designed for so if battery is 160a but the controller is only 20amps it will only pull 20amps

​@@E-bikeguyso i should find the controller open it up and solder 2 parts together? I would love to have a bit more speed and accelration. Nothing crazy cuz i ride in the city and dont want to get hassled by cops. This sounds like a perfect option for me. I can get up to 20 mph throttle and 24 mph pedal assist. So if I do this i should see around 23 mph throttle and 27mph pedal assist? And better acceleration?! Cuz thatd be perfect! Im new to ebikes so do you have a way i can contact you if i need help?

I have what I think is a simple question, but I do not know the answer, so I need an expert opinion. My ebike uses a 48v battery and it has a 750watt motor. I have a second battery, and it's also a 48V. According to my bike display, both batteries are putting out 52vs . Why am I getting 52v from a 48v battery?

I am sorry but I didn’t understand what the modification did. What exactly changed? Thank you

[@sleepingbearffg5008]

There's a shunt in every controller. Tells controler what amps its putting out. By adding solder. It fools controller into thinking its pushing less amps thar it actually is. But will increase heat. There's a gell you can buy to add to controler so it dissipates the heat better depending on controller it might not survive. Depends on misfits they used. Cant look that up too. But if add gell helps allot!

[@E-bikeguy]

Yes we'll I ordered the original controller that he had on the bike before all this happen so h3 had a 80a 3000w controller on the bike, so I did the mod to the 1000w controller and I noticed it can handle more voltage but didn't know how much so I went to 52v to 60v went to the trials to test it out and it preformed great to my surprise it didn't get hot either, it was definitely a noticeable improvement in acceleration and too speed but has nothing on his new controller.

I killed the motor hall sensor with a controller shunt mod because the motor apparently couldn't handle that much power and got too hot.

What kind of motor you had on your modded controller?

[@Bergwacht]

@@E-bikeguy One of those generic China rear wheel direct drive hub motors. The one i killed was from a 1500 watt kit(35 amps). I'm pretty sure that my 1500 watt controller delivered about 2500 after the shunt mod. the modded 1500 watt controller was about as powerful as my current unmodified 3000w controller

[@E-bikeguy]

Oh wow, ok I having a similar problem with my son's 3000w kit, it overheated to so I tell him to be gentle till his new motor arrives, but the 1000w ebike it gets warm but not hot, mainly he is light and doesn't require alot of energy to move bike

[@Bergwacht]

@@E-bikeguy Then of course it would be good if you installed a controller in your sons bike, where you can limit the amps. The only permanent solution I can think of is magnetic cooling ferrofluid. I also thought "then I'll just drive more carefully" But it's so much fun that the heat will be ignored 😁 Unfortunately, my new display doesn't even show me the temperature anymore, so I have to guess when it's getting too hot, that sucks. Even when these motors cooking at 100 degrees Celsius, they only feel slightly warm to the touch.
