Hello!
Do you get yourself a electric scooter?
Great video! One question: If you flash your xiaomi scooter, will this affect the warranty and serial number of the scooter? And can I "remove" the flash or change it back to the default settings?
Thanks for the detailed tutorial!
😁
1. This will remove your warranty. 2. It will have no impact on the Serial Number. 3. You can easily flash it back to original firmware.
@@teamcreativity1779 Thanks a ton! I've found no answer at all online.
@@natagush I'm Happy, to be helpful
Hi one more thing if I chose your speed/ range 12s pack and kept my normal internal battery which battery drains first
12s external is drained first, until it's about 20-30%. Then they are drained together.
Your "hack" is incredible!One question is it compatible with pro 2?
EDIT: Yes it is,I read it on your website.
So it works on the pro 2? Has there been any side effects in relation to the battery, power etc?
Do the pro 2 get also the 20% more speed?
my top speed is 45kmh with range + speed boost kit and i have pro2
@@perunao4823
Hey stock pro2 motor too? Or upgraded motor?
@@CA-RC stock motor
this will work fine on the xioami scooter 3 right?
Yes, but sometimes it's not easy to flash this model. Check if you are able to flash it first. Nevertheless, if you can't - you can still use 10s(36V) batteries with Rita. But you must flash the scooter for higher voltage batteries
Hello my friend can i do this on a aovo pro m365 scooter?
Hi! Unfortunately no. Only original Xiaomi and Ninebot scooters are supported.
The piece of cable you used in 2:50 do i need to have that or did you just use it to pull it out of the scooter?
Any wire is fine)
Can you use this kit on the mi essential scooter?
Yes
Great video! I have mi1s but can't flash with m365downg and I want to buy external battery for better speed (now it is 25kph). Can you recommend something?
I'd recommend joining my telegram community: there are many battery makers - t.me/m365_custom_electronics_en
Hello! Im looking to buy this one but want to use a 13s (48v) external battery. When will you release a video about the installation of a 48v battery with Rita? I remember ypu saying in a video that the installation is a little bit special with higher voltages. Keep up the great work! 🤗
Thanks! Not sure that I will release it soon, because I have a lot of work. Generally, for 48 volts battery you have to
1. Upgrade the controller for higher voltage support.
2. Cut 12s+ jumper at Rita and then connect it regular way.
This information is also presented in the user manual:

Hello, is the external battery safe to drive with during rain? I use my scooter for daily commuting and sometimes there's no choice but to drive while it's raining, which makes me worry that an external battery is a bad idea for my use.
Also, my use of the stock battery sometimes causes overheating during long drives as I modified the firmware to draw more current for hill climbing. Does the RITA adapter evenly distribute the load between two batteries or does it always drain the external one first? I'd just like to know if I should opt for the 12s battery pack over the 10s. Thank you in advance!
Hi,
1. I would say it is safe to ride during rain if your battery is packed and sealed well. My batteries are good enough.
2. Rita drains a single higher voltage battery first. Then, when batteries voltages are equal, the current is shared between batteries. A 10s external battery is the best choice for you, becase it operates together with the internal battery all the time, while a 12s battery must be discharged by 50% before its voltage drops to 41-42V to start operating together with the interbal one.
I watched your video, when you were riding I thought, that looks very familiar. Kraków to Andrychów 😂
Yeah, all polish cities are pretty similar - rynek glowny, zamek. etc). I would say they all are very nice, I like it)
Do you have stock in right now? And how long to ship to the UK?
Yes, I have in stock. About 5-10 days to the UK from Poland
@@DenisYurev hi this kite can be installed on the Dualtron mini with Rita ?
So the batter is like 32Range more!
If i buy a Xiaomi E Scooter Pro2 With 45Range and put the battery then range extends to 77
This is amazing!!! Im probably looking into buying a new E Scooter
And so i can put the extra battery pack on it!
Speed is max 20kmh in germany since this nee law but i need the extra battery for longer range!
45 km at PRO2 is unreacheable in real life. 30 km is the maximum.
@@DenisYurev No i meant the Range 45 and with the extra battery it gets 77range
But the speed is 20kmh and stays 20kmh since the new german law we can't drive e scooter more than 20kmh on streets public
Whats the load time of the two batteries (36v two times) is than 18h
iam used the original m365 battery and an additional 36V 10Ah battery(liitokala) for around a year.
The charging time with the original xiaomi charger for both connected was 6 - 8 hours.
If you use a cheap China charger, as is usually included with cheap China Batteries it can really take 12 - 16 hours+
I don't know how Rita affects the loading time, iam using the 12s now.
greets :)
Denis ur the best! New sub bro :)
Thanks!
*can you hook up another battery with different voltge or does it have to be the same. Example 36 V and 48v?*
I aiamagine no, just connect the same voltages but people on a fb page say you can. Thanks for the response
The main idea of Rita adapter is to be able to connect 36V and 48 batteries together. The answers is: yes, you can connect 36V and 48V batteries in parallel using my Rita device.
Отличное видео! Спасибо
Thorough asf 💪🏋
brilliant, makes a lot easier, when first using can you use normal charging port, or will it require another charger to first charge external to same as internal
Hey I just ordered an extra battery to do this but now found out that the one I ordered can’t be charged in parallel with the xiaomi, it has to be charged separate - can’t be charged thru discharge wires. Hoping this won’t be too big an issue. If you have any advice or tips or anything plz do let me know. Thanks
Hello mate! Very good this tutorial!
Can you send all the pack(increade the speed and battery) to UK?
Hello, I was able to send parcel to the UK 2 weeks ago, but for now there are some difficults due to COVID and BREXIT. Hope the troubles will dissapear in a few weeks since the UK and EU arranged the trading deal.
@@DenisYurev how much does your pack cost for UK
What does the extra batteri do?
I want to do mine to be how can I see you
Thank you Dennis
You are welcome!
Hi Dennis sorry for the vague question which is I have a 48 volt battery without data wires on it only 2 wires charge wire and power wire the controller has had bms skipped I’m not using xiaomi battery at all can I still use Rita with this set cheers
No details , what is the device 🤔 you put there ?
Where you buy all battery kit??
How is that with the charging of the battery? Is it charged with the original charger or must the spare battery be charged separately?
If the external battery is a common port BMS equipped(one couple of wires for both charging and discharging), then it may be charged via the scooter charging port together with the internal one. If the external battery is a separate port BMS equipped(with a dedicated charging port), then it is not safe to charge batteries together, because Rita charges an external battery via its discharge port, while a separate port BMS is not able to interrupt charging at its discharge port, which may be dangerous.
Another thing is the battery must be a 36V one, otherwise original charger will not able to charge it, and you need a new higher voltage charger
This is amazing. Does it work with my Mi Scooter 3?
Hi, yes, it works, but you have to ensure you are able to flash your scooter: the thing is the newest scooters are protected against installing a custom firmware and not hacked yet.
@@DenisYurev i already flashed my Scooter with xiodash. So, it works right?
@@tripertronic6065 Yes, it's 100% compatible then
In the specs table with the external battery and only the internal battery, what would be the difference with the rita and without the rita in the case with the external battery? i mean is it the speed, the range in kilometers or the longer battery life?
+20-30 km range, +20% speed, a little bit more battery life since tle load is shared.
i push 43km on my xiaomi pro on standard mode, 30% at the end of the trip (this is really slow 21 kph, on sport mode i think the range will be much lower)
I would love to test how an external will affect the pro model that already comes with a 70% larger internal battery than the regular.
My regular m365 only gets at best 20km on standard mode.
I tried my same trip in sport mode and I would estimate make 32km range. I cut the trip short at around 50% mark so I would have charge to return. Only made it about 16km one way, had about 15% at 32km but the batt said 5% the next day just left in my room.
Are you still not shipping to the UK? Do you know when you will be able to?
Hi! Yes, I am still not able to ship batteries to the UK. I have no idea when DPD will resume the service.
@@DenisYurev Okay, do you recommend any websites I could buy the battery? I don’t want a cheap rip off
Do you sell this extra battery pack as a complete kit?
Sir,,,if idon't have that rita still have no problem for the connection...tnx sir Dennis ..
Hi Dennis, You are doing great work. Do you plan to modify your products to suit the Xiaomi Pro 2 soon?
Hi, it is compatible with PRO2
Thank you for the video. I would like to ask some questions:
1. i got Ninebot G30 Gen 1 which is 36V and I bought another 36V battery from AliExpress which had really good reviews and sells. Do I need Rita adapter in this case while connecting in parallel?
2. In what scenario can external battery explode or something?
3. Do I need to charge these batteries separately, or while connecting them together I can charge them?
4. Do I need to flash my controller if they have the same voltage?
very nice video, thanks for your time
When i plug the scooter in to charge will it only charge the stock battery or will both charge and if both charge will it increase the time of the charge
Hi, both are charged. Of course, charging time is increased
@DenisYurev the only ones I found are solt in abroad Europe I want to buy one but unsure if they ship to the UK
we ship to the UK@@thekawaiicookie3267
I have a pro 2 with stock battery + 14ah 36v in parallel and I'm waiting for my Rita to be shipped so I can add the third battery (48v 14ah). What do you thing my real world range will be? 😀
Can you please also explain me how Rita works? When the bigger battery gets discharged, it becomes disconnected internally by Rita? If so at what voltage it gets disconnected? Thank you!
Hi, with the 48V 14Ah battery your range will get multiplied by x1.8, like you had 50km, and it will become 90km.
In your setup the 48V battery will supply the scooter until it is 42V(almost empty, like 10% left)
Then all 3 batteries will work together until the voltage is 39V(empty 48V battery, it will be turned off by its bms)
Then your 2 batteries operate like you never plugged the 48V one.
@@DenisYurev hello! Thank for your answer!
I'm also planning to upgrade the mosfet and traces. I found IRFB4110 100V 180A/670Ap 370W 0.0037R (130A). How far could I push the amperage in the settings being very safe on the controller? I did 1800km on 29ampere without any problem so far
@@giorgioika There is no simple answer, I'd recommend joining my public group in telegram and ask there: t.me/m365_custom_electronics_en
This two batteries how much km work and we can use two batteries by one time conetted
Maybe you explained it in the video but do you need to recharge the external battery separately or do you use the usual battery charging hole and it charges both at the same time ?
Hi, both batteries are charged simultaneously via the standard charging plug
@@DenisYurev Oh ok cool, also what's the difference in terms of what is in the package you ship between the range boost and the range+speed options on the website ? What changes ?
@@majorpandaru150 Range+speed battery is a higer voltage one, so it grants extra speed, but requires a new higher voltage charger
How is the battery selected,? Or are they connected in paralell due the Rita?
They are "balanced" like they would connected via 2 diodes. The higher voltage battery is discharged first, until the batteries voltages are equal, then they are being discharged together "in parallel"
@@DenisYurev thank you
Hi Denis, I just want to ask what is that application on your phone that shows all the times voltages etc???
Hi, m365tools
Hello man, thanks for the wonderful video! I want to mod the battery of my Xiaomi Essential, would any 36V battery pack work without modding the Firmware? Appreciate it
Hi!
1. If you want to replace the internal battery to another 36V one without special Xiaomi data connector - you have to flash the scooter to let it accept batteries with no data line.
2. If you want to connect an external 36V battery, using the Y-cable mod - you have to flash the scooter to avoid wrong switching to the charging mode when current flows between batteries.
3. If you connect an external battery throught Rita - no flashing is required, you just plug and ride.
@@DenisYurev Thanks man! I am going to use Rita anyways! Gotta get some extra milage! :)
whats the link of that pcb with connectors
Hi Denis, will you be uploading the internal battery upgrade solution video anytime soon? Looking forward to that one.
Hi! Yes, I remember I promised, but I have suspended the internal battery project a bit. I will release it later. At this moment my priority project is Ninebot MAX version of Rita.
Hi, do you happen to know by any chance if the mi 3 battery is the same as 365? Thanks
Hi, it's the same.
Are you Russian living in Kraków? I am going to order boost kit, you have done very great job my friend!
Thanks)
Sorry Dennis can the Rita be used without the data line from the 48 volt aftermarket battery it’s the Monorim 48 14.4 mah battery
Yes, you can use an internal 48V battery without data lines via Rita. Just don't forget to set Rita properly(set 13 to the "Internal battery serial configuration" parameter) and cut the green jumper
Can I do this with my xiaomi essential scooter?
Yes
Hello does this also work for the xiaomi essential scooter and one more thing does this drain your battery
Hi, it works with Essential. What do you mean "does this drain your battery"?
I have m365 and I burned my controller. I need to get a new controller or to fix and make it better in order to buy this kit? Stock m365 controller can handle safe this battery? I am asking because this battery has more Volts than the original. Thanks!
Hi! Stock controller can handle up to 12s batteries, so it is safe to use it with my kit. I would recommend to join my telegram group - t.me/m365_custom_electronics_en , and ask there for a new controller, because there are a few guys who resell high quality already reinforced controllers.
Can i connect 12s battery in rita adapter without bms or i must connect with bms
Does this work for pro 2?
Yes, it is!
Hey Denis!
Can i still use the Standard 250w Motor, or should i get a 350w Motor?
because with the speed upgrade i have a higher voltage right?
Because im thinkin about getting a higher watt motor so it works better when i buy the speed and range upgrade for my xiaomi pro 2
Hi, stock motor is fine. Most of "350W" motors you can see at the market are mega shit. You know, you can go to a shop and buy a 1.5L milk instead of 1L. But it does not work with motors at all, it's not enough to just compare 250 vs 350, there are many other parameters and especially quality.
So i need now extra connector to load the second batery of 36v
How do I get hold of RITA attachment to enhance operation of scooter?
Hi, I did not understand the question.
Do you have to charge the battery pack separately?
Where can I buy the external battery?
Last question that might be 2.
When you bought the external battery, did you have to take it apart, if so then where did you buy the blue plastic wrap to hold the batteries in. I hope you read this message.

Hi Dennis I have a 365 pro 2 and I’m putting in 48 volt internal battery could I use your 12 s range battery as well
Hi, no you can't. The Rita limitation is that internal battery voltage must be less or equal then the external one. 48V internal battery is 13s, so you can use it together with a 13s, 14s or 15s external one.
We don't sell 13s external batteries, so if you want to by in my shop, the perfect choice is 12s internal + 12s external.
Cheers Dennis
Is it supported for a Xiaomi essential?
(Please answer because I need to add one)
Yes, 100% support
@@DenisYurev damn they're too expensive, but it's disappointing that today I went for a ride less than 10 kilometers (even though its meant to support 20) and I ended up walking on my way home because it was only one blinking red bar and I live in a hilly area, meaning that with the slow acceleration* it wasn't gonna do sh*t. I'm hoping that tomorrow will be better because the temperature Wont be cold at all like today which was like 9° Celsius (and I've heard the colder the temperature, the shorter the battery lasts). So I'll see. Either way, I can't buy it, so I'll have to wait 1-2 years for my Essential to not be able to carry me anymore, so I'll have to sell it and buy something like the Pro 2, which my friend - fellow rider owns.
*By the way, do you know if I can somehow turn off the thing where the lower the battery is, the slower the Scooter accelerates?

If you use a 10s external battery, then you can charge both batteries with the original charger. You need a new charger if external battery voltage is over 10s. And please note, that an external battery must be equipped with a common port BMS to be charged via the scooter charging port.

Was this added in series or in parallel . Trying to get my wires right . + & - to the correct side coming out of the controller . I think the controller shod have a +&- so with two batteries to add power you have one battery’s + from one battery and - from the other battery going to the controller. Then the + & - that’s left gos together. Is that right. I’ve got a 36v am adding iver 12v or 8v battery. To add power to 42or48v
. Plus I think I will need to use a relay so it will work when the 12or 8v is switched off. As I do plan on having it as a Opp and not all the time running that type of power. One more thing not sure what u think about controllers. But I think it’s better to over power the controller as if it’s a 48v one there is a low V cut off. So it cuts off at 38v.
Hi Dennis I have a 48!volt battery with no data cable can I still use Rita on my xiaomi with another 48 v battery for more range
Hi, I did not get the question. Do you use a stock internal 36V battery? Or you replaced it? Or you are going to replace it by a 48V one? Or you want to use 2 external 48V batteries?
Hi Dennis. What is the most hassle free way of doing this? The 10s kit will charge with original charger, show correct battery state while driving and while charging? I don't care about top speed, its illegal here in Sweden anyway, I don't want to risk getting stopped. I only want extra range.
Yes, 10s is the simplest. No new chargers, plug and ride. And yes, proper charge level displaying.
I have a Xiomi essential can i make the Batery on this Scooter ??
Does anything apart from volts matter for the battery
Sure,
1. The battery must be powerful enough to provide about 30A output current
2. The battery must be a common port BMS equipped, which means just one couple of wires for both charging and discharging, without a dedicated charging input.
Why can’t you use the exact battery from another 365?

@@curtisss the problem is your battery BMS. It has a dedicated charging input(separate port BMS), so it's prohibited to parralel this kind of batteries with other batteries. You need a common port BMS equipped battery with a single couple of wires for both charging and discharging.
Do you ship to the United States?
Hi. What if I have a second Xiaomi essential scooter and want to take out the batter from it and connect it to my main one, does the way how I do it changes from the one presented by you in the video?
Hi!
It's NOT SAFE and STRONGLY NOT RECOMMENDED to use an original Xiaomi battery as an external one, because its BMS does not protect it from overcharge via its discharge output. You need a battery equipped with a common port
BMS, while the original one is separate port BMS equipped.
@Denis Yurev thanks for the answer.
Does the battery capacity shown from the both batteries on the scoter display or just the internal capacity? 🔋
Just the internal one.
Denis can I use the original charger to charge both batteries together?... I suppose not but I ask anyway....
You can do it if both batteries are 10s(36V)
If at least one of your batteries is a higher voltage one, then you need a higher voltage charger to charge it.
Hi Dennis,
I have an essential scooter and just received Rita 4gen.
But now I’m aware of my 10s4p battery is with two different cables. One for charging and one for discharging (usage). Not with a common port BMS.
1) Will I be able to use that battery with Rita 4gen securely if I ensure to disconnect external battery when charging. And ensure external battery is charged using external charger?
2: The essential charges batteries in running mode when I brake. Will this setup damage something when using an external battery without a common port BMS using Rita 4gen?
Looking forward to hear from you.
BR René
Hi!
1. The most convenient way for your separate port bms equipped battery is to leave two Rita charging lines not connected. That allows you to keep the external battery connected during charging, and just plug 2 chargers at the same time. Check more information in the user manual is "Batteries charging" section - public.embedden.com/Rita/Docs/English/rita_manual_latest_en.pdf
2. Generally, in theory, it may be unsafe, because recovery current goes to an external battery via its discharge port, which can not be disabled by a separate port bms. But in real world this situation is almost unreacheable, because recovery current is not too much to overcharge a battery. Even original Xiaomi battery works this way.
Denis i need to talk to you please. Im a 100kg guy in a city with hills. I have a pro 2. I was dumb and updated to last version. What can i do to have more torque to go uphills? Controller? Firmware? Paralell battery + Rita?
Hi, first of all you have to flash a custom firmware, like XiaoDash or ScooterHacking. Then, the cheapest and simplest hardware upgrade solution is mounting an external battery in parallel using an Y-cable. Rita is not essential for your purpose if you are ready to spend some time to discover the topic. Or you can just buy the "Range boost kit", it is plug and ride.
Hello can you explain to me the part when you use your phone after connecting the battery 4:02 4:03
Does both of them charge when you plug in the original charger?
If you use a 10s external battery - yes
If you use a higher voltage battery - no, you need a new higher voltage charger
