Good Video! Saving this for possible future upgrade to my Kepler, after warranty expiration. Edit: 3 months later, and I went ahead with a second battery placement, and Wow! Definitely Recommended. Should have did it sooner.
Great video. I was about to do the same to my kepler but I did not want extra wires all over my kepler. Lucky for after searching for days I found the exactly same 52v 20ah battery. Now I have 2 batteries and would rather just swap when first battery is low.
Swapping is good but you won’t have strong torque and range as good as dual battery. Also single swap creates more heat on single battery vs dual which is less stressed and is cooler temp when used in parallel
Nice Neat Set Up MrMtr999, I just spent a week researching the interwebs & YT and I just ordered a blue low bar Kepler for myself after what so many people are saying how you can't go wrong buying one. 25 - 35 miles range is enough but if I was going on a special trip what to do for longer range? Now I know, thank you sir.
i ordered an aluminum chassis box to put my 2nd battery in. it's 12"x8"x3". i'ts pretty low profile at 3 inches and should be more than strong enough to support the weight of a storage bag on top of it. it should be big enough to hold the battery, wires and a little padding to hold it in place. also, if your seat is high enough you can mount it on the rack with the box pushed almost to the seat post. i plan to paint it flat black first. i'll post a link to the box in the comments of this.
What do you plan to cover it when there are rain or snow? It does not seem waterproof. Unless it comes with PU rain cover too. Also, the battery should not be bouncing around in the box, it will degrade or damage its BMS panel, it has to be tight or fixed similar to downtube battery or rear rack battery, no movement or play. I use 2 real rubber straps to hold my bag with Kepler rear rack with padded foam inside, no movement or bounces, besides PU rain cover that comes with the bag. Just saying. Good luck on the project, well worth it. Keep us posted.
Would love for this to be in tutorial format. how are you pulling the connections from out of the frame? How do you avoid causing any damage? Just got my Kepler and I absolutely love it, the extra range would be an absolute dream if i can get it
Thank you for this video! It makes me want to get this bike (short range is scary)! But I was wondering if you think that someone 5'6 would be able to fit on it?
Nice!! This is exactly what I planned on doing with my Kepler but with sm twist. I wasn't sure if I was going to be able to do it because wasn't sure if Kepler used XT60 connectors so big thanks for showing me that I will be able to do my dual battery setup no problem 👏🏽👍🏽💯 Question what is the amp rating for your battery blender is it more than 30A ?
Just got mine finally on Friday and after I took it through the steep hills in the area I was like...yup, definitely going to want to run dual batteries on this thing lol. Glad someone else was able to dig into this before I managed to mess up all my wiring trying to figure it out myself. lol
@@DnSAdventures no cutting or splicing, everything is xt60 and ext60 extension 14awg wire to reroute and connect. If you cut a single wire on the bike that is wrong.
With 40 ah @52 v or 2080 WH, you can go 80 miles distance @20 mph easily. So with full throttle only which is a lot faster than 20 mph, i would guess 60-70 miles depending how aggressive riding is. I might do video on that if i have time, but the math already tells you the answer. Thank you for watching.
You used the caps to tie in the spare battery to an extension wire with an xt60 plug? Maybe you did that to not need to solder and shrink wrap for the time being.
This Bafang motor is supposed to have a 1800w peak. What's been the peak wattage you've experienced? Watched a video where, on a 18% grade the Kepler slowed to 8mph peaking at 1300w, throttle only.
Inside are plastic planetary gears, not metal gears! There are few owners already need to replace gears so i din’t expect much out of it! Ride conservatively as an ebike, go like mid 20 mph, avoid severe hills or walk it up. Don’t throttle it and expect much, it will last otherwise you will need to replace inside gears very quick. My 2 cents
Wouldn’t it be easier to just plug in the second battery as necessary when riding? If the first one gets low, stop and replace it with the alternate one.
You can do that way too if you like carrying 2 nd battery around every time you ride and swapping every time you ride. It is preference and less burden/heat on one battery when riding 30 mph mostly. Nothing wrong doing swap if you are fine with carry them.
from FBC site: "The FBC isolates the batteries from each other; they are never electrically connected between them. In light of that they do not charge together, and will require separate charging."
@@vpham92688 i have separate chargers fir the battery, each one has its own charger, different manufacturers. That is why i use FBC blender, no need for identical battery when paralleled.
Nice mod! Im looking just to buy a second battery and keep in a case on the rack. Anyone know where to get a stock battery , availability and price?? Thank you!
You can search, but i know the battery Kepler uses is called Reention Kirin 7 model. I don’t think you will get any battery from Ariel Rider, i saw some 17.5 ah for Kirin but not 20 ah.
I just asked Ariel Rider yesterday and they said the following: "We will most likely release batteries for sale in late summer for around $600. " So a bit more expensive than aftermarket 52v 20ah batteries, but I imagine they will have a better warranty than something we can buy off amazon. Still debating which way to go myself. :) - Shane
@@DnSAdventures i won’t believe them till i see the battery, but again why i have to wait since i can get from UPP cheaper and 1 week shipped? Just me saying lol… good luck
@@DnSAdventures im debating as well as far as which way to go. If you add an aftermarket battery our warranty will be NG on electrical componets so there is a big risk. Thank you for that information.
@@MrMtr999 Haha yea for sure. I'm real close to pulling the trigger on the same design you went with, just have to measure to make sure I can still do everything else I was planning on doing with the bike as well. Probably end up towing a small cart behind for extra storage if the battery takes up too much room on the rear rack (if I go that route).
Best video of Ariel Kepler by far!! Mine is blue You make me consider doing the same thing to my bike 🤔 appreciate you.look forward to more of your videos.
It really increase range significantly and less stress on your original battery, you will see the battery percentage hardly going down when running 26-30 mph fir a period of miles. Thank you for watching👍
The xt60 wires are listed in description, you can buy 2-3-4 set, I did not cut or measure them, you can use them together connected to go as many feet as you wanted. On Kepler I just used to extend from controller and battery. I did not cut any single wire, fyi. You have to DIY and figure how you want for the length.
This may be a dumb question, but would you be willing to do a tutorial on this? I want to add a second battery to my kepler as well but im worries about breaking something when I start disconnecting the wires from the stock battery and controller. Is it as simple as unplugging it from one thing and plugging into another? Thank you.
Yes, it is plug and play, no cutting wire not a single wire on Kepler. If you cut a wire on the bike you did it wrong. I probably have to do a video on this setup soon, so many people asked. I will try to post new video when I have time off from work and life. Thanks for watching.
@@emaguigad if you want 60-80 miles range you have to go Pas1 and little throttle, pas1 topping 21 mph on the Kepler, and keep pedaling that speed you will go far far. 21-22 mph that is fast enough to reach destination in no time fie ebikes. I know cause i have it. Ebike any ebike going 30 mph or above throughout is not safe, imho you need steel frame or body like onyx or motorcycle to sustain that speed throughout feeling safe. Any mistake @30 mph will break your bones and be very dangerous if the bike fail or snap. It is just my experience. Everybody is different, i know. Good luck.
Joshua Padovese: sales09@unitpackpower.com That is the email of Luna Xie, she is sale mgr/associate of UPP, she can help you. Tell her you want 52v 20 ah, 40 bms $325 plus fees, shipping included. She sells through Alibaba. If you have account it is faster taking 3 -4 days shipping from Texas. Good luck.
@@MrMtr999 Oh, so it was all just plug and play? I thought the batter was opened and not it is hard to close lol. I have a Kepler too, would love to look forward to your updates on this, if all goes well i'd jump on it too. Only thing i like my to use my rear rack allot with stuff in the bag.
@@MrMtr999 so you disconnect the batteries from the fbc and charge them separately? Is it not possible to leave them connected to the fbc and charge both batteries by putting 1 charger on either battery?
@@toneighty6913 you don’t disconnect anything when charging, each battery has its charger. When done charging, disconnect charging ports and go ride. That is all.
@@MrMtr999 oh, ok, I got it now. Thanks. I’ve been having my Kepler for a few days and so far I really enjoy it. Thanks for the info. I’m sure I’ll eventually add a second battery too.
@@toneighty6913 eventually you have to, you will find that one battery won’t last long on aggressive ride like 26-33 mph all the time, juice gone fast. Once 2 battery it is a lot stable on percentage. I love it. Very easy to do on Kepler it is all xt60 no cutting or splicing with controller wires
Hi, it is shipping damage, the plastic locking tab broke off, could not close tightly, the electrical tape works but i used a bundle on it. The replacement battery takes 6 months or longer from China and Ariel Rider don’t have any spare in stock. So be cautious on this subject. Kepler uses Reention Kirin 7 type, you can find 3rd party and swap out if so. Also the tape protects against the rain pretty well from experience. Thanks for watching 🙏
@@MrMtr999 are you happy with this mod that you did? I am skeptical to modify new bike but do want the extended range. Appreciate your time and feedback!
@@LouisEvangelista007 Absolutely love ❤️ the mod! I ride Ebikes to and from work, range is priority then speed. Without mod i have to be carefully on speed not much of 30ish but with mod i can ride free night time home and only take 20% off the full charge round trip! You will see huge difference in battery stability and percentage besides you can ride fast or slow without range anxiety. It is day and night. Sir
@@MrMtr999 wow you did this already? You have only had your bike a short time. Thats awesome. Did you use all parts from the post ? How long did it take you once you received the parts to complete. I am very techy and hands on.
