Thank you for explaining the cons and difficulties that you might encounter doing thus modification Most guys just say that you you will get more power and don't point out any negatives so thanks for a complete and honest review.

I really appreciate your honest opinion on this matter. I bought my 1st E-Bike in 2017 and immediately started modifying my URB-E PRO GT folding E-bike as I was bored with a 13 MPH top speed. Shunt Mods have been around for many years. I figured why bother for mid torque upgrade with almost NO top speed gain. The Freedom E-Bikes have a ton of torque for a 26 inch tired E-Bike. Thank you for your time to test these alternatives.

Thanks friend! Glad you enjoyed the content. Happy to have you as a subscriber.

You are brutally honest thank you!

Great job!!! Thanks for making this! About on par with the test controller I have. Throttle only in windy conditions (normal conditions in Wyoming)about 41-42. If I pedal like a mad man with the 60T chainring on the front 43-44. Hoping they’ll have it even more refined by the time I get the V2 Power Goat. Really interested in what you achieve with your controller project.

totally agree, just upgrade your controller for more raw power and faster acceleration and if you want more speed get your battery voltage upgraded too!. A Great video look forward to more...

If you want to keep the heat dissipated in your motors, just add statorade to the magnets of your motors and heat sink blades. They will run nice and cool. Luck!

Statorade? Is that like Gatorade…for e-bikes?

@maximumchargeEV

I did look into that but it seems like I won't need either one because it just isn't getting very hot. I also hear statorade doesn't age well and you have to add it in every year or so and it makes a mess in your motor. I probably won't need it but if I do I'll add it.

Thank you sir for that. I do understand doing too much for a little. I would like to find a plug and play 100amp controller and call it a day.

I'm thinking about a 72v 6500 peak watt kit 80 amp controller, using a couple 25ah batteries on the Kepler platform. Huge rear rack should handle a big bag of goodies. Not sure what to do with the 52V battery. Just leave it for looks I guess. A $3,500 Kepler that goes over 50 mph sounds good to me.

Very interesting to learn how the battery blender works. I have one connecting two 48v batteries, one has a 30A BMS, the other is 25A. I didn't know that they split the draw from the each battery's BMS. I was worried that if I put a 30 - 35 amp controller in [stock is 22a], that the BMS might shut down. Good info, thanks.

You'll get about a 17% loss with that blender. They're not super efficient. I was able to bring that down to around 7-8%, making my own blender. Great video, keep it up!!

@maximumchargeEV Basically, the mosfet in the those are not cooled properly, and it's poor quality. I reused the housing but built a better circuit with better parts . I don't want to give away too much, as I'm in r&d and plan to sell them when I get done testing. I want to be 100% on safety and durability before I put the out . Price is looking like 60ish for a 100 amp constant and peak 120 amp .

Just out of curiosity when you were doing your shut mod did you happen to see what the maximum voltage the capacitor were. If they are 100v then you could run a 72 volt battery with stock controller

commenting as i watch...could you use copper wire to wrap the controller pieces (like a winding) and then solder? Would it do anything?

@maximumchargeEV

4 ай бұрын

I'm sure that's been done before but then you risk the wires falling off. You could use a solder wick to remove the solder later on.

Would I like to know is on some of the older radrunner bikes they have upgrade kits to 35 amps. I'm fairly certain that the original controllers were 18 amp controllers. I'm fairly certain that the batteries only had like a 20 amp discharge rate. So how did they do it?

@maximumchargeEV

4 ай бұрын

Need confirmation on that battery discharge level.

@trsdamocles

4 ай бұрын

@maximumchargeEV can't exactly confirm but what I could find is the radrunner has a 48v 14ah battery and I think a 18 Amp controller. Weak.

@trsdamocles

4 ай бұрын

@maximumchargeEV my experience has shown on three different ebikes that companies don't go much more on discharge rate than rated output. Senada had 28a controller, 30a discharge(21ah). Smrlo awd had 27a between 2 controllers and 50a discharge(23ah). Wallke has 28a controller and 30a discharge(40ah).

Can you send me a link to that USB-C thermal camera you are using?

Hey @SolelyElectric, Thanks for the comment friend! Appreciate having you as a viewer.

Make the custom 17s battery and charge it to 71.4 volts ;)

Wait a minute I was told the shunt mod comes with nitrous lithium...lol

I thought a "shunt mod" was putting a second resistor in series with the amperage sensing resistor to fool it into seeing less amperage. Those looked like fusable links in line with either the power in or out cable. You probably only got that boost because more amperage was able to get through the circuit not that the circuit was outputing more current.

It would give you less range for sure since it drains the battery faster.

No, you should 100% fine blending the batteries. The blender will pull from the highest charged battery ( the tank battery) first, just like stock. When it drops down to the voltage of your other battery, it will pull from both.

@@dtcrouch100 my goal is ride out the warranty and then if something fails, drop a 5000w on the rear and a full frame battery with an option to charge at charging stations like the Harley bike.

seems like the shunt mod isn't worth it over all........but a second battery is. You would probably get better results if you got your second battery from Goat Power, they have one made for that bike that matches the original in total voltage.

Too much heat for a part that's not designed for that much heat, then it melts and breaks.

Why does the law say you have to have pedals and limited to 28mph? I would think you would be less of a traffic hazard if you're able to keep up with traffic. I am in a rural area and to leave my house, you have to ride about 3 miles on a 2-lane state highway with a speed limit of 55mph (meaning traffic is running 60+) before you can take a side road to go anywhere. I would love to have one of these and ride to work, but I'll get run over if I'm doing 28mph (although cyclists do ride their bikes out here during the summer - stupid).
