Thanks! Your 2.0 looks identical to my T42 and I'm planning a rackbag battery, similar to your setup.
Let us know how it works out😎
@@ElectricAllWheel Imagine your Lectric with 1100W peak, 80nm torq, programmable display/controls, hyd brakes, 4" fat tires, bigger battery, 22A controller and 34mph top speed... Thats my T42... It came on my Bday, Nov28. So, Nov28 this yr, my wty expires and I customize my electrics... Meanwhile, I'm working on a stubby folding stem, BMX bars, and putting miles on this lil beast! Debating on adding a 48V30A and a Bolton battery coupler or Going for a 52V30A and a Blender from SparkCycleworks... OR, add a 48V20AH parallel and a 12V80AH in series for 60V to the motor!?!?! Heat buildup may limit that setup to winter rides. LOL
I’ve always wondered how to add a second battery. This seems like a really great idea.
It works great!

Another thing you can do if you ever want to free up your rack space is to mount the battery mount to the frame using some Gorilla mounting tape. It's a very strong hold and it puts the extra weight closer to the front of the bike which is better for weight distribution. Since you're tall you should have no problem with step over clearance. The tape forms an extra strong bond with whatever coating is on the paint. When I attached more batteries I had to pull out the excess cabling from inside the frame to make room for the new battery connections. The XP has way too much excess cable.
I really love that you fit the small 20 amp balancer into the controller bay, that's the first time I've seen it done. Probably because most folks use the larger 30 amp types, but it's gonna get hot in summer where your palm trees are I bet. I am going for a similar setup with my 2.0 XP, and I now think a couple of small cheap thermocouple wires between and on the controller and the balancer are maybe not a bad idea. The reason being that those devices have components that can get hot without good airflow. It's probably fine, but expensive if it actually does form hot spots. That said, awesome POC build man!
Thanks! The 20A was chosen to match the controller. The current is limited so it’s anticipated that heat dissipation will be minimal especially considering the potential possibilities of a new 30a controller with a matching new 30a discharge balance. Thank you for watching!
@@ElectricAllWheel Totally subbed to keep an eye on where you take this build. So thanks for sharing! I have a 30 amp balancer and a 30 amp BMS on my new 48v/20Ah battery now which this controller will never ask to draw that many amps from. So if you go with a new controller, that sounds very cool indeed to see, now that I am just out of warranty. :) Take care.
Bought my Lectric last month and its so much fun,but im still riding my Trek Dual Sport 2 as daily. That extra weight around my belly has to come off , but man ebikes are so so much fun. I get 22 miles on one battery.
Trek is a great bike. Definitely an enjoyable ride.
@@ElectricAllWheel how much was your total with the battery?
All the goodies were around $270. The links for the separate items should be in the description. The discharge balancer makes it all worthwhile.
Always offset your solder connections so that they are NOT opposite each other. You never know when the friction gremlins will show up.
I have the same stock battery and I get over 35 miles on a charge (with a bit of charge left). I weigh 235. I do peddle all the time but at speed 4 (mech shifter) and rarely go to electric speed 3. My peddling is always comfortable, up hill or not.
Small note about electric safety - *make sure both batteries are fully charged before connecting them.* It's not unsafe to connect batteries of different mAh in parallel together it is however unsafe to connect batteries with different voltages together, which they will be at different levels of charge even if they have the same "nominal" (READ: IN NAME ONLY) voltage. At this level (48v) the chance of an explosion is small but not impossible, and the Discharge Balancer box makes it even less likely, *but not impossible.* Its job is to ensure continuous discharging safety, if you put two batteries into it with wildly different voltages one time, *expect smoke.* And you should also be concerned about extra wear, the batteries will try to even out their voltages which will cause extreme heat which will cause the cells to fail earlier or even possibly leak/puff up. The key is to have both batteries at the same voltage - so technically you could match them ~80% to ~80% charge level etc, but it's better and safer to not think about that and just fully charge them before connecting. Also never let the batteries drain unevenly, either use them both at the same time, or only connect them once both are fully charged
Just for the safety some electric bike dont have portable batteries. Is it safe to charge both batteries while connected to the balancer with the controller?
@@detroy183 If you're asking if it's okay to charge both batteries with one plug - I wouldn't call it "safe". But if they have similar voltage profiles and charge times, I don't think it's likely it'll end badly. I'd ask an electrician though
Nice video. I love the upgrade on mine. I had my battery mounted on the rear rack just like you. I have now mounted my battery on top of the stock battery on top of the beam. Keep up the good work.
We put on the cargo baskets and in the back of my head I kept thinking “look at all the places to mount batteries!”
@@ElectricAllWheel I was in the same situation as you. I originally wanted it mounted on the center beam on top of the stock battery to leave the rear rack space but couldn't screw into the frame or the stock battery would not slide in and out. It took me time but I figured it out. I wish I could upload a pick on here to show you.
We have seen your bike in the FB group!
@@juanescorza2984 I am planning to mount my 2nd battery to my step-thru coming next week too.
Even if you could slide the main battery out you should never drill holes into that frame that can let water seep in, without at least some rubber seals, the battery compartment should be sealed from the top at least, rain and moisture will find its way in and wont find a way out and corrode battery terminals, connector pins, and anything not sealed.
Hopefully the frame is 3/16 of an inch thick then you have enough thickness you can drill and thread-tap blind holes into the frame, with enough threads to hold the battery secure.
Btw, the engineering for thread strength is only 1.25 x the bolt diameter into a properly tapped threaded hole is being held by the threads, so basically a short bolt provides as much load-holding as a long bolt in properly tapped holes.
If the battery holder is too thin to tap, I would epoxy some threaded nuts to the top of the battery beam, if I had a MIG welding gun that would be best but you would have to grind off the paint to bare metal at the welds, then paint the nuts to match.
If this battery had a mounting plate with full flat contact, I would probably epoxy the mounting plate right to the top of the frame.

As an automotive technician I can tell you you always want to hand solder your connections and close up with shrink wrap because using solder balls or solder masks can add too much resistance to the wire
I use a similar setup system. But I turn on the key to the battery that I want to run my bike. I do this so I can tell which battery is getting weak and needs to be replaced. I like the idea about those no solder clamps using the heat gun. I will have to get myself some of those for sure. My Lectric 2.0 with the dual battery I am giving to a friend as soon as my Lectric Premium gets delivered because I like the mid-drive motor versus the hub drive. Great video I enjoyed watching it.
We are jealous of your premium!
Also, you will love the solder seal connectors. So convenient.
Sweet idea. Now I want to do my lectric 2.0 step thru. 👍👍😎😍 because I only get 25miles
You won’t be disappointed

Great video.

Everything does not fit in there. Not without compromising connectors and bending the crap out of wires. Maybe with the new xp's there is more room. The balancer looks like it needs to mounted externally on the first gen XP. I do not feel comfortable mounting it inside with the controller as there is t even enough room for the controller and stock wires to begin with. I'm trying to do it now on my own XP.
Keep in mind that you can extract some of the same existing factory cable from the housing to give yourself some room. They often leave excess cable in the controller compartment. We neatly wrapped excess cable with zip ties on a few of the 2.0s and 1.0s that we have performed installations on recently
@@ElectricAllWheel prior to seeing your reply I ended up pulling the excess blk wires out as much as they would go wrapped in blk wire loom and mounted the balancer externally while still keeping a good look. Love the kit and extra distance.
If the capacities of the batteries are different, how those batteries will depleted? At the end of the trip, their voltage will be it equal?
The balancer balances voltage. If one battery is more charged than the other it will draw down the voltage to that of the other battery then uniformly discharge both.
Check out some of our newer videos for more info
Great video. So approximately 45 miles is the advertized range on the stock bike. What's your range with the dual battery? Tx!
We humbly request forgiveness for not EVER being so frugal with the “gas.” Our guesstimate is dual batteries discharged with conscious thought towards assist, while having zero regard for hard starts and speed limits… 20-30 miles at 250 lb rider weight.
How tall are you? I'm 6'6" 250lbs. I ride a Overfly Hummer-S with a 750w bafang. Thinking about doing a second battery install.
6’2”
Shoot us an email if you have any questions electricallwheel@gmail.com
Great video, you made it look easy. I really have been wanting to do something like this on my XP 2.0. Just wondering if would be okay to use a 48 volt 20ah battery from Unit Pack Power that says, Max Constant Discharge Current:30A/50A( BMS) Or is this too strong for the controller?
The Lectric controller (18A-20A) and discharge balancer will “control” so yes…yes you can😎

Por favor hay alguien que en santa clarita realice la instalacion
pronto tendremos una solución plug and play para un Lectric. Vuelve a consultar pronto. todo lo que tendrá que hacer es desenroscar la tapa, enchufar las piezas y volver a colocar la tapa.
Can a discharge balancer be used with a brushless direct drive hub motor?
Yes
Thanks for sharing this upgrade. New sub here. How much range did you end up with. My EP 2.0 is on order and range is my biggest concern. Thanks again.
This is all dependent. Weight, throttle usage, etc.
In the most relatable way possible, at 245lbs with a speed addiction and zero regard for battery preservation, I anticipate 20 miles while the batteries are brand new.
This was done to ensure a days worth of excessive overindulgence for new young ebike riders.

Would it be more economical to simply buy an extra XP 2.0 battery ?
This setup allows you to ride both batteries out without having to change one out. I suppose that would be based on your personal preference. Thanks for watching
I’m in for a longer run time also. I have a 20aH battery I’m installing.

Hello, where I can get this type of connector to external battery what you add to the rack of the bike?
electricallwheel.com/how-to-install-lectric-xp-dual-batteries/
@@ElectricAllWheel i bought controller but on the video you have external battery which connected to its own quick connector. Connector was mounted on the rack with zipper lock.
@secondlife7976 check on the link provided toward the bottom for the external battery adapter.
Quick question: I brought my bike on vacation, but forgot my external batteries charger. If I reinstall it, will the extra battery charge thru the lectric charger? Thanks!
The charger will need to independently charge each battery but should work for both.
If you bought the recommended battery the factory Lectric charger will charge it
Could I add a 10 ah battery to the 14 ah that comes on the counter long range with this ?
Yes. Ah doesn’t matter. Just make sure voltage rating matches.
You don’t need to do any soldering
agreed. th-cam.com/video/u41Y4tgx-3U/w-d-xo.html
Nice job. My ebike has a 22A controller. Does it matter if I use a 20a, 30a or 40a battery balancer?
If you used a 20A balancer it would be the limiting factor. Any balancer larger than that and the controller will be limiting
Great video. Can you post a link for the bike stand. Thank you
Hi Richard. We posted the link for the exact stand in the video description. We might suggest something more durable, but as you can see, it has done the job for us.
@@ElectricAllWheel thank you. Missed in the description.

Can you charge both batteries while they are plug in with the balancer and the contoller? Or can charge one battery at a time while plug in with the balancer?
With the current set up, the original battery is charged as normal in the bike. We simply disconnect the second battery when charging it. The connection is easily accessible.
Can u charge both batteries trough balance charger at once with 1 charger
The balance discharge in the video doesn’t have this capability, but they do exist with that capability
check this out th-cam.com/video/u41Y4tgx-3U/w-d-xo.html
Do you know if anyone have done this with the Sondor XS Fold. I am a heavy set guy and would like to get a spare battery for the bike to add extra distance.
Can you share a pic of your controller (specs sticker) and the power cable from the battery?
ElectricAllWheel@gmail.com
What would happen if you used the 30 amp version ? Would you go faster ?
For 30A to matter you would need to replace the Lectric controller as well. A quick check with the rear hub current limits would be worthwhile as well as BMS discharge capabilities. However, the beauty of Lectric is the customer service and warranty. Keep that in mind as you move forward! Thank you for watching.
I'm curious if I'm gonna need to do this. I'm about 260 lbs and I'm planning on trying to ride about 20 miles per day. Just curious how many miles you were getting before adding the second battery?
Do it. You’ll want the freedom of choice. You won’t want to be confined by conservation of battery.
At that weight and an average 14-16 mph throttle, you’ll need double.
Dollar for dollar, it’s an excellent investment.

I have some steep hills, not long gradual hills. Will this help or do I need to look into a stronger motor?
Lots of factors involved in that. Your riding style. Whether you pedal. The intrinsic value of your bike.
You’re never going to hear us shy away from a special mod like a new motor, but that will require an upgraded controller and associated components. You might consider selling and acquiring a bigger motor and higher voltage system.
@@ElectricAllWheel I have a “Specialized ground control” mtb that I want to convert. It’s to tall and I think putting 24” rims/wheels will help. I plan to peddle it like a regular bike but would like to be able to get to where I’m going faster. I won’t be going on trails or off reading. I picked the bike up dirt cheap. I’m aware of the amount of money I will put into it. I figure it was a better investment than buying a much heavier bike ready to go.
We have a few build videos that might interest you. Check them out. ….we apologize ahead of time for the music
Any suggestions to upgrading or hacking the controller to drive more power ?
Officially, the motor, controller, battery BMS, as well as balance discharge would all need to be matched for max current. Heat will become an issue.
The Lectric controller is a 20A controller. The balance discharge is as well.
Unofficially, you might be intrigued by a Google search of the phrase shunt mod.
Remember there are limiting factors from all components listed above. Heat becomes more of an issue as well.
Can i just purchase tplug to xt90 converters and tplug female/male extensions from amazon to avoid soldering? 🤔
Xt60…yes

how much is the used lectric xp2 in avg now? did you get it from fb marketplace?
We would expect a price of $700-$800 dependent on use, accessories etc.
Yes, one was purchased on marketplace.
@@ElectricAllWheel great, thx for all the useful info!
how long was the xt cable that goes from the balancer to the 2nd battery on the seat post? 12"? TIA
2ft will provide a length that will allow you attached to rear rack. Any excess can be coiled in the bag.
check this out th-cam.com/video/u41Y4tgx-3U/w-d-xo.html
Do the batteries need to be off when you charge them at the same time?
It is good practice to do so, regardless. However, we charge the original while still in the frame. The second battery is easy to unplug, so we do.
check this out th-cam.com/video/u41Y4tgx-3U/w-d-xo.html
How do you charge the batteries? separately or have to remove them from bike?
The original stays and is charged normally while in the frame. The new one gets unplugged and charged separately.
@@ElectricAllWheel is it a must that you disconnect the external battery before charging it?
@@jimbianca9560 We charge the internal battery as normal. We pull the connection for the second battery for precaution prior to charging.
It is not anticipated that the back feed would damage the discharge balancer, however the ability to help prevent any issues is too easy not to oblige.
@@ElectricAllWheel thank you so much.
@@ElectricAllWheel would it be easier to put some type of toggle switch vs having to pull the connector every time you charge the 2nd battery?
Is there any reason this isn’t doable with the Lectric XP 2.0 step-thru?
Nope. Put the balancer in the bottom. It’s actually easier than the regular XP2.0

Feedback
amzn.to/3S7DFjg
How does the battery work with this? Like does it use up lectric battery first then the next one or both at the same time.
Both. It’s a Balanced discharge to the low voltage cutoff of the controller.
@@ElectricAllWheel will it affect the bike if one is fully charged and other isn’t
It’s is good practice to treat the system as if the balancer is not there and you are running batteries in straight parallel. This would require full charge and twin specs. However, the point of the balancer is to compensate for the scenario you describe. Just be sure your spec voltage for each battery is the same. Meaning, a Lectric is 48V. Do not use a 52V or 36V battery.
@@ElectricAllWheel thank you. By chance is there any way you can see or like check if the wiring that you did might be wrong.
