Thank you sir, just performed this upgrade, only charged it twice since new so battery is NEW...ive only had it a couple weeks. I love this upgrade...THANK YOU for posting for us ignats...
A nice video, but definitely a dangerous task if you either don’t know what you are doing, or work carelessly. I appreciate seeing the inside of the juice battery, and thanks for sharing your upgrade!
CRAZY .. My results after 15.6ah upgrade ... stock camp scrambler .. avg 16 - 17 mph .. throttle only on level 1 speed .. after a distance 40.2 miles .. display showed 48.4 volts .. 12.6ah used .. display still showed 2 full bars left to kill .. 60+ miles with pedal assist is doable .. imo .. HIGHLY RECOMMEND
I tried this upgrade on a bike i just got this month (nov 2020) and they apparently change the form factor of the battery so this mod isnt possible with the newer model from what i can tell. :(
@@vanmasterflash7153 could you advise on what cells to get for this mate. Watched your video over 10 times since I got my bike in 2019.. Do I need a new bms if I keep the voltage the same but increase the Ah?
Thanks for this video! I am glad I saw it. I was thinking about getting the 19.2ah battery, now I can save some money and do this instead! After you measure your battery pack and it was 54V and the 14 cells yield 50.4V. You later said, "you wanna bring the battery down a little bit, you wanna match the voltage pretty close". What do you mean by that? What battery are you "bringing down"? Are you referring to matching the 14 cells voltage that should come close your battery pack voltage?
@3cheerz thanks so much for posting these super helpful videos! I tried your link for battery cells and they seem out of stock. I'm having a hard time locating the at an affordable price. Do you have any other recommended suppliers? Thanks again!
This only works on the 2019 model. They removed the empty row and made it more difficult to do as soon as they saw people were upgrading for $50. Sry, I’m not sure where else to get these cells right now.
@@vanmasterflash7153 previous owner said that it was purchased in oct 2018. Crossings my fingers that when I open up the battery I find that there’s extra slots!
My Scrambler battery all of a sudden only charges to 50%. With only 750 miles on it, the company will not warranty it. Any suggestions as to the fix? Great video, btw.
Sounds like a it could be a bad BMS. I don't have any good leads on a bms but Rick Rowen does. Now whether he gives you a link or tries to upsell you one is another story. First make sure your battery charger didn't come slightly unplugged during charging. In other words try it one more time. If that doesn't work keep pressing Juiced for a battery replacement. If that doesn't work and you feel comfortable with this, take your battery apart and look for obvious problems like bad solders and/or connections. Also look for burn marks and burnt smells. If nothing appears out of place it's almost certainly your BMS.
Please be careful with 18650 batteries, folks. And they are everywhere. Each one is a small incendiary bomb that makes a road flare look like a birthday candle. And they will set each other off in a chain in the case of thermal runaway. Avoid cheap manufacturers who cut corners on the inner insulating strip. I spent 11 years as a hazmat guy, Lithium batteries were my #3 most common waste stream (and #1 most expensive), and one of my key jobs was discharging, classifying and packing Li-Ion batteries of various types for recycling/disposal. Never, ever 1. Use ones where the shell is even nicked or scratched 2. Use cheap brands that you got a "good deal" on. The bulk of them, even when they have someone elses name on them like Tesla, are made by Samsung & Panasonic, which are fine. Beware: there are bootlegs of those brands all over the market. So if you see a hot end that is oddly sunken or non-standard, you probably have a fake, and that's not bueno. Even if the markings say "Panasonic" 3. Be cavalier with a heated device like a soldering iron. Apply heat, and you can cause thermal runaway which ends in an explosive burst of super hot fire, and no, you can't stop that chain reaction, you have to douse the rest of what caught fire with a B fire extinguisher 4. Get them wet or allow moisture to build. Ventilation, humidity reduction, and protecting the shell of each individual 18650 battery are key. 5. Make a habit of throwing them in the trash. Put tape on the ends, stuff them in a plastic zip lock bag, and *_take them to Home Depot or Lowe's for recycling_* I love the ton of power in my Scrambler's battery, but after seeing the things I have, I treat the thing like a White Phosphorous shell sitting a foot away from my balls when I ride
Great job. I don't have an e-bike yet and doing research on whether to buy one or not. It seems there are many areas problems can occur in a new purchase so maybe I'll stick with my old built-up Bridgestone assembled in 1980. Thanks
So did he use the solder in place of welding? I know you need the special welder which I have been thinking about getting. Great video. I am trying to rebuild a ebike battery and this helps
Yep that'll work just fine. For BMS its all about charge and discharge amps. If you planned on running a anything over 35amps you might need to go bigger. Not sure on how much the stock BMS can handle. For charging I wouldn't go over 4 amps but it might be able to handle more.
Great video! It is possible! Have you had a chance to test it out? Did it give the bike both more power and range? I have a black camp scrambler with the 13ah battery and would like to upgrade if it makes a decent deference.
We still have a couple feet of snow on the ground here. Won't be till late March early April till I can ride. It won't add hardly any power. For that you'd need to increase voltage. It will increase range and make life easier for the cells in your battery. If your getting 20 mile range on 13 Ah, then 15.6 should get you about 25 miles. More cells but also the cells discharge slower when less amps are pulled from them. It's a no brainer for me but everyone is different. BTW I think soldering and battery building is fun. It's hard for me to keep my hands off these things.
3cheerz I just finished mine up a few mins ago. Sad to say it took me like 3 hrs , and definitely didn’t look as nice as yours. Powered up though so I’m happy. My battery was draining pretty fast. I took the 750w motor out and put in a 2000w leaf bike motor and 48-72v 3000w controller with 3speed switch that added soooooooo much more power . I soldered the shunts in the controller with also added insane low end. The speed switch #3 my bike get 64.7mph with no load and around 53mph with me on it. Your info on the battery was amazing and saved me probably a grand so I thank you my man!!
+3cheerz What's the highest amp hours that scrambler battery can be upgraded to. Because if it can a higher amp hours than 15.6 I would like to do that. Because Juiced Bikes has a 19 amp hours version battery.
Highest reliable is around 3500 mah each cell. That would be 3500 mah x 6=sweet ass 21ah battery. The cost would be $430 plus, using LG mj1 10amp cells.
I've only rode it once because we've still got a ton of snow and ice here in mn but I love it. Rides so smooth and the brakes are awesome. Plenty of power and seat is super comfy as well. No complaints so far.
Just finished my upgrade. Not as easy as you make it look. Is there any way to know that it worked besides milage tests ? It was to cold and rainy to ride more than a few miles today and I didn't notice anything different on the display or anything.
Not sure maybe in the advanced display. It takes a long time to solder all that but it'll be worth it. It will help your range and greatly improve your batteries life.
You'll need new nickel strips. If you're planing on soldering smaller gauge copper wire will work fine. Spot welding with new nickel strips would be the professional way to do it. If soldering make sure to use a minimum 60w soldering iron and keep a wet rag handy to cool them quickly.
@@vanmasterflash7153 Thanks for your suggestions! I've done some minor soldering work before. I have 2 original batteries on Juiced scrambler and hyper scrambler that need to be replaced. Juiced prices are really high. Any suggestion on where to get the batterie cells (your description link is no longer useful)?
Not sure but lets find out right now. My 13 ah city case is 15-1/2" x 3-1/16 x 5-1/2(eyeballing the bulge). If yours is the same size then the answer is no. More than likely your case is the exact same size as mine and you have higher capacity cells. Maybe these www.imrbatteries.com/lg-mh1-18650-3200mah-10a-flat-top-battery/
Charge time and range will for sure be longer. Not sure of exact numbers. I did the upgrade before the snow was gone. It's not hard but the soldering is time consuming.
I just remembered that you live in mn like me. Cold weather causes more voltage sag. I’m starting to think it’s the low voltage cut off. I sure hope so anyway. When it warms up you should see a lot better range.
I have the low voltage set at 42. Can't be connections as the battery itself is turning off green light goes off. Could it be an out of balance battery tripping the battery protector?
No what you want to do is to group you Li-ion batteries individually by *Internal Resistance.* Otherwise you'll degrade your entire pack through *Imbalance.* Sorting Internal Resistance within 5% or ideally within 2%-2.5%. End result is is dead pack with damaged or dead cells. More information batteryuniversity.com/learn/archive/non_correctable_battery_problems

Either way I’m not disassembling my entire pack to test all cells individually then group them like I did when I made my other battery. Not worth it. It’ll be just fine.
@@vanmasterflash7153 .. It'll be fine until either your range deteriorates quickly or the pack fails .. hopefully NOT spectacularly.

That's the only place I've purchased cells. Looks like they're getting hard to find. I'll keep my eyes peeled. I only have one extra laying around :(
Couldn't you just use nickel strip for everything instead of the copper wire? Want to do this for my batteries this week since I'm stuck at home.
Yes. Only reason I used the wire was because it made it easier to solder.
@@vanmasterflash7153 Cool. Now only if there was a way to get the pack out without cutting off the charging port!
Awesome video!! I just ordered the stuff to do this with mine. Curious, did you notice any low end torque or high end speed after doing this?

Nope same voltage more range.
What does the controller voltage do? Would the malfunction of that unit cause my battery to only charge 50% capacity?
On the button side there is a small yellow connector glued to the the cover. What is that for?
I was thinking the same thing. Looks like another connector for charging or something. I just ignored it. If you figure it out i'd like ot know.

Bad Ass! Thanks for sharing.
So you just bought these cheap 3 dollar batteries? Would higher end batteries with higher mAH be better ?
Just better to keep cells the same. The amount you'd gain with one row isn't worth the mix imo.
So did you notice a longer range? what about the the charge time?
Charge time and range will for sure be longer. Not sure of exact numbers. I did the upgrade before the snow was gone. It's not hard but the soldering is time consuming.

@@trahar6257 Hi, what controller did you get for your bike? am still shopping around for a good one. thanks
My battery starts shutting itself down at 47 volts. Any idea what might be wrong?
Not sure. Your battery shouldn't be sagging below 42v but maybe. Did you try setting the low voltage cut-off to 40v?
It could also be battery terminals loosing contact where the battery connects. But if it shuts down at the same voltage every time it's not that.

Was 60 degrees today and still shut off at 57.7 same voltage as before, display shuts off then battery light dies out.
Why didn't you use nickle strips for all the connections?
It was easier to use solder the wire and works just as well if not a little better. Having a spot welder would be best. Someday i'll get one.
Thanks looking forward to upgrading my camp scrambler
