I found a marine rocker switch with the same specs. It is flat, black, water proof, and if you are careful, you can install it out of immediate sight. Having a kill switch no one can see is a wonderful security measure.
I just saw the older video and Left a message about the parallel the battery, I am gonna delete it coz you just answered it! you are so awesome! Thank you Shiva!
If anyone wants to connect 2 batteries in parallel safely, Use a diode Isolator or a full wave bridge or a dual diode center Tap Common Anode diode set to isolate the batteries. The current will never try to equalize between the batteries. The only con to this is, the 0.7 of a volt drop across the diodes to the load or motor control. So there will be a slight top speed loss. You will still need to charge the batteries separately. The pro to using the diodes apposed to a switch is the current will be provided from both batteries simultaneously for more power for when you are pulling hills. It also can be located near the control and no need to extend the wires to a switch located near the handlebars, its automatic load sourcing. Shiva you can comment on this a approach. Note: The Diodes Must Be Rated for 20 Amps or above. The Voltage Drop across the diodes is a 2.6% loss of Power to the Motor at full current.
Hi Thomas, that is an excellent idea! Diodes would provide that benefit of simultaneous current draw from both batteries. However, the controller has a limiter at 10A, so even if you can draw more current, it won't be used by the controller. Both of these batteries can output about 30A each, but only 10A is being used. I recently upgraded my controller and I can now safely draw about 13A, giving me higher speed and a little bit more power. Thanks for your very detail insight, this is interesting and useful. I really appreciate it.
Thanks for the great vid. Just one suggestion. You can hook all the ground wires together and just use the positives on the switch. Also,,, Im not so sure that type of switch will handle the amps . Using either all the positives or all the negatives will eliminate the chance of a short circuit on the wires going to the switch too . Awesome job on your vids and clear explanations of your instructions . Thanks for that ..... Chuck

Thanks Shiva, I’m looking forward to making this improvement on my bike(s) very soon. The parallel was greatly helpful, but I’ll take your advice and go with the switch. Connecting and disconnecting the xt60’s is a little tedious. Thank you for both your time and contributions to this ebike. You have helped me a lot !👍🏻
Hi Ray, thank you very much for your continuous support to my channel. I will continue to bring more videos about this bike on a regular basis. Please reach out with any questions/issues while you make this modification.
for those considering a parallel connection, Bolton ebikes sells the Dual Battery Parallel connector which allows you to use the different voltages when the two batteries are not charged evenly.
I believe when you connect two batteries together of the same voltage the amp hour doesn't really matter. All you are doing is creating one bigger battery. Be sure to disconnect the batteries when charging and be sure both are fully charged before you plug them back together. If you charge both batteries while connected with the charge port on the bike you will be bypassing the BMS in the extra battery. In time the extra battery will become unbalanced and shortening the life of that battery. Best to disconnect the batteries and charge both to full before reconnecting. If a battery has high resistance it will self discharge itself and if connected in parallel with another battery it will discharge that battery as well. Have fun and keep the shinny side up. 😎👍
Hey my friend I have a same bike so sometime they give me problems usually I buy they give me a good time for a week for jarzan but now leaving me hot time so what kind of banner is good for that
Know this is an older video, however, I have a question: are you concerned about the amount of amps that are going thru the switch? am interested in doing the same thing but with a rocker switch. don't want the amps to fry the switch. Have a Rad Rover with duel 48 volt batteries and the upgraded 35 amp controller. would something like this work for me?
Yes, I thought about doing that. But, for now, the stock battery combined with the higher capacity Ebay battery has been working well for me. I get enough range to get around but once the stock battery dies out, I will for sure just buy a larger capacity one. Thanks for watching my video.
good video I'm going to watched later before I go to sleep I was wondering if you can do a video on how to fix a flat tire in case if I get a flat tire..but like all your videos they are great 👍good job and keep up the good work greetings from my home town Anaheim California close to Disneyland..
Hi Frank, yes I have been looking for tubes and tires that fit this bike. I am also researching on slime to see if that would fix a flat tire. I promise I will do a video on that but just need to get some research done prior to it. Thank you again Frank for always supporting my channel.
So, technically correct with the battery balancing info, however, if your system is balanced initially and charged with the same charger, you have very little to worry about in terms of cell damage in a parallel configuration. Because you have 2 cells very closely and evenly matched, there is no need to be concerned with a parallel connection. I think the issue really becomes when charging. If you are using different chargers for the batteries, cell balancing becomes an issue. You should be able to use the jetson bike charger to charge both packs at the same time if you use the parallel method - it will just take a lot longer. You can further reduce load balancing risk by replacing the jetson battery with another ebay battery.
Hi Josh, thanks for your insight. As I said in my video, it could be just my personal preference and what makes me nervous about the parallel configuration. I would be much more comfortable with parallel connection of two ebay batteries as you said. Since Jetson doesn't really provide any info about the original battery, you can only assume things about the internal resistance. I am by no means an expert and my knowledge is limited to past experiences and college Chemistry haha. So, I really appreciate your input. Thank you.
@@ShivaSapkota you could make a measurement of the internal battery resistance by measuring the open circuit voltage, then drawing a known current, and measuring the voltage drop from the open circuit voltage. Divide the difference by the current, and you have the internal resistance. Easiest with an electronic load, but you can just measure the current with an ammeter, and use that for the calculation.
You can buy the xt60 connectors and then just buy bulk wire instead of extensions.. then you can run it however you want. It would be nice to put the aux battery in the front somehow because of the already rear heavy cog
Wouldn't it be easier just to plug in additional battery with only xt60 connector for charge and work? I did it for my MiniPro 11 (it is ananlog bike) with 36V4,4Ah battery even it appers to be 2,2Ah because of weak umarked 18650 elements. Nevertheless it helped me to get to my job and even back with one charge. I did it once but now I prefer charging my battrey twice just to be sure.\ With my heavy body (120kg approx) one way is about 7 kilometers. Pedalling and throttling - 50/50.
You’re a godsend! I’m building a bike right now and came across an issue where i see things sparking with I connect and disconnect the battery from the controller. I heard that if you install a switch between the battery and the controller and turn it off before disconnecting, the sparks will go away. I have no idea what switch I’d need or how to but it in between the battery and controller. Could you please advise? Thank you 🙏🏻
Hi Shiva...great work, you are good at this. I bought one of these bikes but would like to add a battery. Unfortunately , I live in Canada and the Ebay seller does not ship it here. Could any 36 volt battery work ? I noticed in another video you mentioned something about amp hours. Does this matter with respect to the circuitry / controller.
Thank you for your videos, they are very detailed and really well explained. I'm looking to get two Jetson bikes but my fear is about fires. I have always been warned against batteries made in China, what do you think? Also, I live in Canada where winter temperatures easily drop to -25 Celsius and even colder. What do you suggest for storing bikes in the winter. I was thinking of storing only the batteries in the house, but here I come back to my first point, the risk of fire. Thank you very much and keep up your good work.
Thanks Landon. I have the controller installed but yet to verify the speeds I am getting. I am already liking my new controller a lot more than the old one as it offers various customization such as 9 different modes for speed, initial power, lcd display etc. Stay tuned for that video soon. Thank you.
Great videos. Is there a way to add a key ignition switch to power on? Would an alarm immobilizer also be a good idea and something that could be added? Thanks
Hi Joffre, that is an interesting idea. Let me look into that for you. I am sure we can figure out some sort of a "Key". The alarm system would be rather complicated. Thanks for watching my videos.
I got this one. It works and I really like it better than on the stock controller as it has 9 different throttle/pedal assist modes, lcd screen and you can even change how much instant power you get. It is loud though. I have yet to test the speed. You have to change the number of magnets in your motor and I have no idea how many they have. That determines to speed. So, I will have to calibrate using a GPS speedometer. I can probably do it this weekend and post a video next week. Here is the product: amzn.to/3ykmMId.
Thanks Shiva, very helpful definitely got me thinking about an additional battery. By the way I noticed you install a mirror, leave a link so I can order the same. Thanks
Hi John, thank you very much for your support. Here is a video where talk about the mirror: th-cam.com/video/qTVJeKgIXKQ/w-d-xo.html. Here is a link to my Amazon list with all the accessories: www.amazon.com/shop/shivasapkota
So after 3 weeks of switching between the battery’s myself and getting annoyed at the long process, I’ve finally ordered these parts to add a switch...lol
@@ShivaSapkota thanks dude! I've got a spare 48.1v 17.5ah battery + 48v 10ah battery for my Kugo kirin B2, total weight including bag is 7.5kg.. I think this should be fine since rack is rated for 9kg.. What do you think? Will have a dpdt switch 25amp 250v installed for battery's.
Where is the link to the tool, and do you use 48 v 20 ah lithium battery? It looks like there is a size, and i dont understand the difference of battery number?
Hi William, no you cannot use a 48V battery. It can only take a 36V battery. You would need to upgrade the controller to use a 48V battery. Thanks for watching and please reach out with any questions.
thanks a lot man you are the only person who explains this properly to somebody , big like , i decided to do the switch version, i have one battery 48v 30ah and another 48v 15ah will this switch that you used be ok for this ?
Thank you very much!! Check the amp rating on your batteries. I think you will be okay but you can also email the seller asking if your battery is compatible. I think switch is good for 25A.
@@ShivaSapkota bigger battery is 48v 30ah it can be used for up to 2000w motor , it says in specs on the website where i bought it : BMS: 20-50Amp continuous 50±10Amp maximum Charge Current: 2-5A Charge Cut-off Voltage: 42V/54.6V Discharge Cut-off Voltage: 30V/40V Discharge Temperature: -20 to 65°C Charge Temperature: 0 to 65°C do you think i will be fine using this switch ? i allready bought it it is coming today from amazon ?
I hope you are doing well? Question ; How far should we let the battery run down before charging it? Finally got two bikes for wife and myself. Thanks again for the informative videos. 👍 Rick
Hi Rick, these batteries don't really have memories, so you can charge any time. I wouldn't drain below 10% and charge to 80 - 100%. Overcharging these batteries (keeping it plugged in after full charge) would hurt the health in a long run. Hope you are doing well!
do you know if there is a 5v output inside I can tap into? I have a collection of old iphones and I was thinking about placing one inside securely that I would be able to track on icloud in case of theft.
That is a great idea. Yeah I believe there are multiple 5V outputs (throttle power and ground, power button cable (red/black) and even the headlight has power. I think the throttle one might be the best to tap into. I did a thumb throttle video recently and that video shows the power cable for the throttle. Thanks for watching my videos.
Hi Shiva, great video. My only question is, does the Amp rating for the BMS in the aftermarket battery matter if doing the secondary battery with the switch?
Hi Eddie, I don't think it matters. The switch is rated for 20A and I think the extra battery has that same BMS (could be a bit higher) but it worked for me. As far as the bike, it has a 10A limiter, so no matter what the battery discharge, the controller won't send more than 10A to the motor. Thanks for watching my video.
@@ShivaSapkota Thank you for your quick reply and providing of many details. I was able to get my hands on a Bluetooth module with Controller from the older Jetson Bolt, that used to be sold directly from Jetson. Do you have any idea if doing the speed unlock with that same older Bolt Controller would keep the pedal assist?
Thank you Shiva! I am interested in replacing my original Jetson battery with the one you bought from ebay. Please let me know where I can get that, plus all the connections I need to fit it into my Jetson Bolt Pro. Thanks again!
All those exposed wires will look horrible. Should drill into the plastic panel where the stock battery is installed to make it look factory and keep moisture away from the elements like moisture. Water will flick up from the rear tire if installed under the rear rack and too exposed on the handlebars. But keep up the good work and vids bud!
Thanks for all the info in the description :) All parts ordered except I couldn't see a link for the extra charging port. Did I miss it? Thanks for any help
Shiva, this is incredibly helpful, thank you for all you do and for figuring out everything and showing the easiest ways to modify the Bolt Pro. Have you considered a front wheel second motor? It’s something I’m considering and I just wonder if you’ve thought of it too! Not to increase speed but better for hills. Also how can I find your email so I can send you all of my swagcycle mods?
Hi John, I have considered a dual motor mod. That is much more intense process but I plan on doing it in the future. My email is sapkotatechnology@gmail.com. Thanks John!
Hi Shiva , my name is Bhagwat ,live in near Ann Arbor Mich. Any help upgrading battery pack to 36/48 volt and a controller made by Brainpower 36/48 volt,13Amp.I have run in to connecting proper color coded wires that do not match.On my LCD I get an error code # 10,that is related to throttle not getting power and not turning the wheel. There is a very dim green light I see on the throttle.The red wire from the controller to the throttle should have 5 volt hat is not there.Any suggestion will be appreciated Hari Ohm !
Also can I just stick a stronger hub motor without altering the entire controller battery set up without causing damage? Can I upgrade battery. Hub motor. Or controller individually to improve performance at all ? Or does it require a full kit change. I’ve never owned an ebike
It heat up a little bit but I think that is normal. I haven't had overheating issues. The switch is rated for 20A and the controller limits to 10A. Thanks for watching my video.
Excellent video Shiva! I'm going to try the same and get similar some supplies from AliExpress. Do you mind taking a measurement of the width of the switch on two sides? (Difffent widths on 2 of the sides) I want to use shrink wrap around the outer diameter of the switch and then cover the 3 xt60 cables coming of the switch as well. What type of diameter shrink wrap do you think i would need to cover switch and 3 xt60 cables?
Hello, the switch is 1.3" x 0.76" x 2.2". Is that the measurement you wanted? Honestly, you can probably just do electrical tape? Thanks and let me know if you need any additional info. Good luck with the mod, thanks for your continuous support to my channel.
@@ShivaSapkota thank you! Yeah was thinking of keeping it easy. Just don't like the sticky adhesive that some leave. I'll look for some better electrical tape perhaps.

@@ShivaSapkota thanks for the kind words. Couldn't have done it without your excellent instructional videos! I was searching and searching for small enough case and finally found the Wildman 2L on AliExpress. Later found out that Segway scooter guys use the same one for their external battery. Lol. I chanced upon the Aerdu battery brand and found out it's one of the larger brands in China and have good reviews on AliExpress. My particle model is "supposed" to use certain LG cells if they can be trusted. ;) Are you a member of the Facebook groups "Jetson Bolt Electric Bike" and "Dyu Scooter Group USA"? It's a small but growing community of Jetson owners sharing their rides and mods. You can share your videos there too!
@@soupnazi81 Awesome! Your mod looks really cool. Great find on the Aerdu battery. LG cells are the best if they really do have them :) I did join the DYU group I believe, I need go join the Jetson Bolt one.
Hi, can I use a portable charger to charge the battery on the road and that il can plug directly into the hole of the charger for my jetson Bolt pro? If so, what kind of portable charger? Thank you very much and I like your videos! From Laval, Canada!
Hello, yes you can technically use a portable charger but the weight of the charger might diminish its value. I wouldn't recommend charging while using the battery. Thanks.
Thank you very much for answering back! By curiosity what king of charger would you recommend. If i am stuck with no electricity it would be a plus, sitting and waiting for the battery to charge Thank again!!!!
Thanks Shiva, Maybe this question has already been asked, for the second battery, since it is installed on the bike rack, so the size is not matter, can it be 36v 20ah instead of 10ah that you were using in this video (amazing video)?
Hello, yes, as long as it is still a 36V battery, you can go any AH. However, a lot of "20AH" batteries are scam, so be careful. I would go with 14AH to be safe.
After viewing most of your reviews/mods, went to Costco (Canada) bought 2 of them @$359 CAD each, ~ $259 USD...and hopefully add on second ext battery to increase the range
I just got my own Jetson Bolt Pro. My first impression, the handlebars is too short, it is not easy to control. The wheel is too small, it is ok on paved road, but it may lost balance on unpaved road. And my original battery only last 7+ miles.
Hello, thanks for your insight about this bike. The range is heavily dependent on weather, wind conditions and weight. I get about 8-10 miles in the winter but close to 14 in the summer on flat roads. The handlebar are a little short and I also do wish the wheels were a little bigger. Thanks for watching my video.
You don't need to connect all the wires in the switch, double pole connections are not that safe newbie can make mistakes short it, just connect the 3 red wires to the switch and tie all the 3 black wires together and seal it with heat shrink and tape it. Installed my dpdt switch in a waterproof electrical box so it's its even safer more me

Hey man was wondering if u could help since Ik you’re kinda like the jetson bolt Pro pro, my folding mechanism doesn’t have any form of like force at all like the little handle to be able to fold the bike once I take off the little lock that keeps it from popping out it’s super loose idk if you can help in anyway that’d be dope
Hello my friend, thanks for reaching out. That is strange, usually folks complain about how tight that handle is. When you unclip the little handle, do you see a rod in there? If the rod is missing, it would be super loose. If you see the rod, you can actually take the bottom screw of the little clip assembly out (it has a metal washer with a cut in the middle that you can remove). You can remove that and tighten the entire clip assembly by turning it right. You can then put the assembly back together and it should be tighter. Hope this works. If not, I will try to make that one of my future videos. Cheers!
@@ShivaSapkota I’ll check it out later today thanks for responding so quick, this happened because I crashed 🙁 but no parts broke I do believe it just got loose but don’t worry I bought a 40$ helmet from amazon and a scwinn rack for the seat
@@leggomyeggo9088 I am glad you are okay my friend. Give that a try and if it doesn't work let me know. I can further look into ways on fixing it for you.
Hi Shiva, Thank you for your informative videos on Jetson bike. I am really glad to find out the battery capacity can be enlarged. I was wondering if you have any plans to extend your expertise to Jupiter discovery x5, another ebike from costco (especially in areas of battery). Although I am drawn to Jetson's price and modification, I do need a folding bike for my purpose.
Hi Scott, I already have 2 of these bolt pro's so a little hesitant to spend more money on the Jupiter bike. I have considered getting one and doing tutorial videos but haven't made a decision yet. I did reach out to Jupiter to see if they can send me a bike for review but they wanted me to pay basically the Costco price. I also reached out to Swagtron (folding ebike like Jupitor) and they didn't respond...Thanks for watching my video.
I would not put the switch to the front as extra long cable will create extra voltage drop hence extra power loss or heat waste. If someone likes to do it I suggest to put a relay close to both batteries and run small gauge wires to the front with a control switch. It might cost you just a bit more for the extra relay or even less because the extra long battery cable may cost you more than the relay.

@@ShivaSapkota you could make a measurement of the internal battery resistance by measuring the open circuit voltage, then drawing a known current, and measuring the voltage drop from the open circuit voltage. Divide the difference by the current, and you have the internal resistance.
Easiest with an electronic load, but you can just measure the current with an ammeter, and use that for the calculation.
will it charge the extra battery in the original charging port or should I connect both charging wires of both batteries?
@@JOSERIZALADVENTURES if the batteries are connected in parallel to the system so they can be used simultaneously, they will charge from one charger.
Dp you really need the extentions? The 5 pack of those things seem good enough right?..
You can buy the xt60 connectors and then just buy bulk wire instead of extensions.. then you can run it however you want. It would be nice to put the aux battery in the front somehow because of the already rear heavy cog
Wouldn't it be easier just to plug in additional battery with only xt60 connector for charge and work?
I did it for my MiniPro 11 (it is ananlog bike) with 36V4,4Ah battery even it appers to be 2,2Ah because of weak umarked 18650 elements.
Nevertheless it helped me to get to my job and even back with one charge.
I did it once but now I prefer charging my battrey twice just to be sure.\
With my heavy body (120kg approx) one way is about 7 kilometers.
Pedalling and throttling - 50/50.
can I parallel contect a 36v 6ah jetson pro stock battery with a 36v 20ah battery????
My question you think i can charge both battery while there connected to the main that have a switch?
I would add a fire system that switch is not heavy enough there is a heavy doty diode block that will do the job safely
You’re a godsend! I’m building a bike right now and came across an issue where i see things sparking with I connect and disconnect the battery from the controller. I heard that if you install a switch between the battery and the controller and turn it off before disconnecting, the sparks will go away. I have no idea what switch I’d need or how to but it in between the battery and controller. Could you please advise? Thank you 🙏🏻
Excelente, lo sencillo es más práctico.
Hi Shiva...great work, you are good at this. I bought one of these bikes but would like to add a battery. Unfortunately , I live in Canada and the Ebay seller does not ship it here. Could any 36 volt battery work ? I noticed in another video you mentioned something about amp hours. Does this matter with respect to the circuitry / controller.
Great information, thanks Bro...
I have a spare jetson because we upgraded one to a 3 wheeled bike. Can i use 2 Jetson batteries in parallel like that?
Thank you for your videos, they are very detailed and really well explained. I'm looking to get two Jetson bikes but my fear is about fires. I have always been warned against batteries made in China, what do you think? Also, I live in Canada where winter temperatures easily drop to -25 Celsius and even colder. What do you suggest for storing bikes in the winter. I was thinking of storing only the batteries in the house, but here I come back to my first point, the risk of fire. Thank you very much and keep up your good work.

I will be looking forward to seeing the controller upgrade video.
Thanks Landon. I have the controller installed but yet to verify the speeds I am getting. I am already liking my new controller a lot more than the old one as it offers various customization such as 9 different modes for speed, initial power, lcd display etc. Stay tuned for that video soon. Thank you.
Great videos. Is there a way to add a key ignition switch to power on? Would an alarm immobilizer also be a good idea and something that could be added? Thanks
Hi Joffre, that is an interesting idea. Let me look into that for you. I am sure we can figure out some sort of a "Key". The alarm system would be rather complicated. Thanks for watching my videos.
I know you are planning on making a video on controller upgrade. Can you give us heads up on the model you got as mine is dead...thanks.
I got this one. It works and I really like it better than on the stock controller as it has 9 different throttle/pedal assist modes, lcd screen and you can even change how much instant power you get. It is loud though. I have yet to test the speed. You have to change the number of magnets in your motor and I have no idea how many they have. That determines to speed. So, I will have to calibrate using a GPS speedometer. I can probably do it this weekend and post a video next week. Here is the product: amzn.to/3ykmMId.
Thanks Shiva, very helpful definitely got me thinking about an additional battery. By the way I noticed you install a mirror, leave a link so I can order the same. Thanks
Hi John, thank you very much for your support. Here is a video where talk about the mirror: th-cam.com/video/qTVJeKgIXKQ/w-d-xo.html. Here is a link to my Amazon list with all the accessories: www.amazon.com/shop/shivasapkota
Hey boss.. would the "on off on" switch method.. work on a 48volt 34amp vevor controller and 48v 15ah lithium batteries?? Thanks in advance bro👍🏼
Are you located at calgary been looking for to add a battery on my jetson
So after 3 weeks of switching between the battery’s myself and getting annoyed at the long process, I’ve finally ordered these parts to add a switch...lol
Hi Jerry, that sounds great. Hope the switch installation goes well for you.
@@ShivaSapkota thanks dude! I've got a spare 48.1v 17.5ah battery + 48v 10ah battery for my Kugo kirin B2, total weight including bag is 7.5kg.. I think this should be fine since rack is rated for 9kg.. What do you think? Will have a dpdt switch 25amp 250v installed for battery's.
Where is the link to the tool, and do you use 48 v 20 ah lithium battery? It looks like there is a size, and i dont understand the difference of battery number?
Je veux savoir après avoir charger la batterie .si tu utilise pas tout suite elle se décharge
Hi Shiva I have a battery from ebay is 48v 20ah , so this is good o not good Jetson bike ????????
Hi William, no you cannot use a 48V battery. It can only take a 36V battery. You would need to upgrade the controller to use a 48V battery. Thanks for watching and please reach out with any questions.
thanks a lot man you are the only person who explains this properly to somebody , big like , i decided to do the switch version, i have one battery 48v 30ah and another 48v 15ah will this switch that you used be ok for this ?
Thank you very much!! Check the amp rating on your batteries. I think you will be okay but you can also email the seller asking if your battery is compatible. I think switch is good for 25A.
@@ShivaSapkota bigger battery is 48v 30ah it can be used for up to 2000w motor , it says in specs on the website where i bought it :
BMS: 20-50Amp continuous 50±10Amp maximum
Charge Current: 2-5A
Charge Cut-off Voltage: 42V/54.6V
Discharge Cut-off Voltage: 30V/40V
Discharge Temperature: -20 to 65°C
Charge Temperature: 0 to 65°C
do you think i will be fine using this switch ? i allready bought it it is coming today from amazon ?
@@techgeek2994 will a bigger battery make my jetson bolt ebike faster?
Did you ever install the switch? Did you notice any issues with battery draining?
I hope you are doing well? Question ; How far should we let the battery run down before charging it? Finally got two bikes for wife and myself. Thanks again for the informative videos. 👍
Rick
Hi Rick, these batteries don't really have memories, so you can charge any time. I wouldn't drain below 10% and charge to 80 - 100%. Overcharging these batteries (keeping it plugged in after full charge) would hurt the health in a long run. Hope you are doing well!
do you know if there is a 5v output inside I can tap into? I have a collection of old iphones and I was thinking about placing one inside securely that I would be able to track on icloud in case of theft.
That is a great idea. Yeah I believe there are multiple 5V outputs (throttle power and ground, power button cable (red/black) and even the headlight has power. I think the throttle one might be the best to tap into. I did a thumb throttle video recently and that video shows the power cable for the throttle. Thanks for watching my videos.
Great Video! Will your switch handle two 48 volt batteries pulling up to 19 amps....as on the Lectric XP 2.0 eBike?
One question. What if I purchased a single pair cable battery and the existing one has charging and descharging port, can I install them togheter?
Hi Shiva, great video. My only question is, does the Amp rating for the BMS in the aftermarket battery matter if doing the secondary battery with the switch?
Hi Eddie, I don't think it matters. The switch is rated for 20A and I think the extra battery has that same BMS (could be a bit higher) but it worked for me. As far as the bike, it has a 10A limiter, so no matter what the battery discharge, the controller won't send more than 10A to the motor. Thanks for watching my video.
@@ShivaSapkota Thank you for your quick reply and providing of many details.
I was able to get my hands on a Bluetooth module with Controller from the older Jetson Bolt, that used to be sold directly from Jetson. Do you have any idea if doing the speed unlock with that same older Bolt Controller would keep the pedal assist?
@@egntwm From what I have heard, nothing changes other than the speed boost. You just use the app to increase the speed.
@@egntwm have you hot a link for the Bluetooth module please ty
Thank you Shiva! I am interested in replacing my original Jetson battery with the one you bought from ebay. Please let me know where I can get that, plus all the connections I need to fit it into my Jetson Bolt Pro. Thanks again!
All those exposed wires will look horrible. Should drill into the plastic panel where the stock battery is installed to make it look factory and keep moisture away from the elements like moisture. Water will flick up from the rear tire if installed under the rear rack and too exposed on the handlebars. But keep up the good work and vids bud!
Just got two refurbs for $225 each. Hoping to use in our camper while we are out and about
Hey your video for the controller upgrade was taken down you should repost it
Please email me (sapkotatechnology@gmail.com) and I will send you a link. Thanks.
Thanks for all the info in the description :)
All parts ordered except I couldn't see a link for the extra charging port. Did I miss it? Thanks for any help
Thank you for the video :-) yes I want my Jetson to go faster
How much about a battery upgrade can it handle how many 1000 pound 2000 power for 1500 Power
Shiva, this is incredibly helpful, thank you for all you do and for figuring out everything and showing the easiest ways to modify the Bolt Pro. Have you considered a front wheel second motor? It’s something I’m considering and I just wonder if you’ve thought of it too! Not to increase speed but better for hills. Also how can I find your email so I can send you all of my swagcycle mods?
Hi John, I have considered a dual motor mod. That is much more intense process but I plan on doing it in the future. My email is sapkotatechnology@gmail.com. Thanks John!

How can you make the battery charge while your riding the bike ? My name is camper williams
Awesome Video..! Thanks..!
Can the toggle switch handles 48V?
Je veux savoir pourquoi la batrie je décharge. Quand tu utilise pas le vélo.
Hi, want to ask..
Can i use 60V 15AH 18650 battery and 60V 30AH 21700 battery to this parellel connection?
buenos dias disculpa puedo poner en un polo una de 36v y en el otro polo una de 48v gracias
Can you show how to make it go faster than 15mph?
I am trying to bring that video out. I am currently modifying my controller to be able to go faster. Thanks for watching my video.
Can i just get the blue battery withought a extension?
Hi Shiva , my name is Bhagwat ,live in near Ann Arbor Mich. Any help upgrading battery pack to 36/48 volt and a controller made by Brainpower 36/48 volt,13Amp.I have run in to connecting proper color coded wires that do not match.On my LCD I get an error code # 10,that is related to throttle not getting power and not turning the wheel. There is a very dim green light I see on the throttle.The red wire from the controller to the throttle should have 5 volt hat is not there.Any suggestion will be appreciated Hari Ohm !
Can i used different types of switch? And what capacity?
No need fuse for the switch?
Very good video，What model is this battery and where to buy it. Thanks
Does rain not affect this
Where do I purchase the extension cable from controller to rear battery
What do you think of trying to mod up a Dyu s2 with 2x2. And like 500w
Also can I just stick a stronger hub motor without altering the entire controller battery set up without causing damage? Can I upgrade battery. Hub motor. Or controller individually to improve performance at all ? Or does it require a full kit change. I’ve never owned an ebike
I even want to add suspension
Can I use a 48v 14AH with a 48v 13AH
How does the switch perform under load going up hill? Does it heat up or stays cool?
It heat up a little bit but I think that is normal. I haven't had overheating issues. The switch is rated for 20A and the controller limits to 10A. Thanks for watching my video.
Excellent video Shiva! I'm going to try the same and get similar some supplies from AliExpress.
Do you mind taking a measurement of the width of the switch on two sides? (Difffent widths on 2 of the sides) I want to use shrink wrap around the outer diameter of the switch and then cover the 3 xt60 cables coming of the switch as well. What type of diameter shrink wrap do you think i would need to cover switch and 3 xt60 cables?
Hello, the switch is 1.3" x 0.76" x 2.2". Is that the measurement you wanted? Honestly, you can probably just do electrical tape? Thanks and let me know if you need any additional info. Good luck with the mod, thanks for your continuous support to my channel.
@@ShivaSapkota thank you! Yeah was thinking of keeping it easy. Just don't like the sticky adhesive that some leave. I'll look for some better electrical tape perhaps.
Here's some pictures of my work so far. Works well and I get 30km of throttle only range with mine. I also promote your top notch videos. :)

@@ShivaSapkota thanks for the kind words. Couldn't have done it without your excellent instructional videos! I was searching and searching for small enough case and finally found the Wildman 2L on AliExpress. Later found out that Segway scooter guys use the same one for their external battery. Lol. I chanced upon the Aerdu battery brand and found out it's one of the larger brands in China and have good reviews on AliExpress. My particle model is "supposed" to use certain LG cells if they can be trusted. ;)
Are you a member of the Facebook groups "Jetson Bolt Electric Bike" and "Dyu Scooter Group USA"? It's a small but growing community of Jetson owners sharing their rides and mods. You can share your videos there too!
@@soupnazi81 Awesome! Your mod looks really cool. Great find on the Aerdu battery. LG cells are the best if they really do have them :)

Hi, can I use a portable charger to charge the battery on the road and that il can plug directly into the hole of the charger for my jetson Bolt pro? If so, what kind of portable charger?
Thank you very much and I like your videos! From Laval, Canada!
Thanks for answering back!
Hello, yes you can technically use a portable charger but the weight of the charger might diminish its value. I wouldn't recommend charging while using the battery. Thanks.
Thank you very much for answering back! By curiosity what king of charger would you recommend. If i am stuck with no electricity it would be a plus, sitting and waiting for the battery to charge
Thank again!!!!
Thanks Shiva, Maybe this question has already been asked, for the second battery, since it is installed on the bike rack, so the size is not matter, can it be 36v 20ah instead of 10ah that you were using in this video (amazing video)?
Hello, yes, as long as it is still a 36V battery, you can go any AH. However, a lot of "20AH" batteries are scam, so be careful. I would go with 14AH to be safe.
💌
After viewing most of your reviews/mods, went to Costco (Canada) bought 2 of them @$359 CAD each, ~ $259 USD...and hopefully add on second ext battery to increase the range
Nice job.
Thank you very much.
I just got my own Jetson Bolt Pro. My first impression, the handlebars is too short, it is not easy to control. The wheel is too small, it is ok on paved road, but it may lost balance on unpaved road. And my original battery only last 7+ miles.
Hello, thanks for your insight about this bike. The range is heavily dependent on weather, wind conditions and weight. I get about 8-10 miles in the winter but close to 14 in the summer on flat roads. The handlebar are a little short and I also do wish the wheels were a little bigger. Thanks for watching my video.
Hi, my scooter now using 60V 15AH battery, can i buy 60V 30AH battery and make it to dual battery?
You don't need to connect all the wires in the switch, double pole connections are not that safe newbie can make mistakes short it, just connect the 3 red wires to the switch and tie all the 3 black wires together and seal it with heat shrink and tape it. Installed my dpdt switch in a waterproof electrical box so it's its even safer more me
That is a good idea. Thanks for the insight. Waterproof electrical box is indeed a safe choice. Thank you.

Hey man was wondering if u could help since Ik you’re kinda like the jetson bolt Pro pro, my folding mechanism doesn’t have any form of like force at all like the little handle to be able to fold the bike once I take off the little lock that keeps it from popping out it’s super loose idk if you can help in anyway that’d be dope
Hello my friend, thanks for reaching out. That is strange, usually folks complain about how tight that handle is. When you unclip the little handle, do you see a rod in there? If the rod is missing, it would be super loose. If you see the rod, you can actually take the bottom screw of the little clip assembly out (it has a metal washer with a cut in the middle that you can remove). You can remove that and tighten the entire clip assembly by turning it right. You can then put the assembly back together and it should be tighter. Hope this works. If not, I will try to make that one of my future videos. Cheers!
@@ShivaSapkota I’ll check it out later today thanks for responding so quick, this happened because I crashed 🙁 but no parts broke I do believe it just got loose but don’t worry I bought a 40$ helmet from amazon and a scwinn rack for the seat
@@leggomyeggo9088 I am glad you are okay my friend. Give that a try and if it doesn't work let me know. I can further look into ways on fixing it for you.
Hi Shiva,
Thank you for your informative videos on Jetson bike. I am really glad to find out the battery capacity can be enlarged.
I was wondering if you have any plans to extend your expertise to Jupiter discovery x5, another ebike from costco (especially in areas of battery). Although I am drawn to Jetson's price and modification, I do need a folding bike for my purpose.
Hi Scott, I already have 2 of these bolt pro's so a little hesitant to spend more money on the Jupiter bike. I have considered getting one and doing tutorial videos but haven't made a decision yet. I did reach out to Jupiter to see if they can send me a bike for review but they wanted me to pay basically the Costco price. I also reached out to Swagtron (folding ebike like Jupitor) and they didn't respond...Thanks for watching my video.
@@ShivaSapkota mm
hi shiva do you still using the switch ? did u had any problem with switch i was thinking same for my bike too thanks
I would not put the switch to the front as extra long cable will create extra voltage drop hence extra power loss or heat waste. If someone likes to do it I suggest to put a relay close to both batteries and run small gauge wires to the front with a control switch. It might cost you just a bit more for the extra relay or even less because the extra long battery cable may cost you more than the relay.
Your switch needs to be rated for the current draw of your controller and batteries.
Will this still work for a 30amp battery
