Wow I gotta tell you that I love the solution because it creates a lot more range for your bike specially for miles it is so hard to pedal without the battery in so many ways. 👍👍👍
I really would like to do something like this on my scooter, however I am a beginner when it comes to batteries or electronics for that matter - however I do have mechanic skills. Could you consider making a beginner tutorial to understand the different aspects of batteries as they relate to E-scooters? (e.g Wattage, mAH, voltage, controllers, etc.) Thank you already for lending us your knowledge and keep up the good work!
I use 2 batteries of the same capacity in parallel with a solid state switch DC relay voltage 24-52V manual SPST switch combination, but when I switch from the main battery to the sub battery, the capacity drops to about 1.5-1.7. If you don't run carefully, the battery will go up on the way home.
This is a great solution, but only if you plan for disconnecting the external battery for other things than your scooter. Otherwise it would be better to wire them i parallel directly (matching voltages) to take advantage of the lower voltage sag. With lower voltage sag you are also able to drain the batteries more (in case you need that extra range) before low voltage cut off. Also capacity difference between paralleled batteries are not necessary. The bigger battery will take a larger proportion of the load and the voltages will be equalized between the two.
From our experience, connecting batteries with different voltages will result in the higher voltage battery charging the lower voltage battery causing damage in the long term due to the high current surge. You are correct on the voltage sag issue esp for high current usage. But another downside of connecting two different capacity batteries means that you do not maximise each batteries capacity as one battery will be used to charge another. We have found that this method is safer and more efficient in the long term health of the batteries.
@@FalconpevSg in terms of voltage that is not what I said. The voltages have to match very closely when connecting (or else high in rush current will flow from high voltage to low as you say) and of course the packs must have the same amount of series connected strings (eg 13S for a 48V battery). The last thing is simply not correct. You can deplete the batteries even more when they are paralleled partly because of the lower voltage drop/sag, and partly because of lower current draw per series string - and you know from all battery tests that the higher the current draw the lower the capacity.
@@simonmllerkristensen9640 anyway we made a parallel battery for the zero scooters 2 years ago. This is a safer option that is developed with another use case scenarios in mind. The fact is you don’t have to maintain both internal and external batteries at the same voltage is a very big advantage. Check out our parallel battery set up here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ejyIzqAz_tI.html
@@FalconpevSg and that is totally fine. But your understanding of battery capacity are flawed unfortunately. Parallel two batteries is the exact same as one big battery. And a bigger battery (in terms of Ah) have less current draw per cell giving more useable watt hours per cell (check every single battery test with 1,2,5 and 10 A draw)
As long as the battery is voltage matched, you can just wire them in parallel and you don't even need a switch. They will balance charge. I've done it on my M365 clone.
That’s what many non industry people believe. Voltage has to be matched and also within a certain charge voltage. If one battery is at Low charge and one is full charge then it’s bad for the Low charge battery to be charging and discharging
@@FalconpevSg Yes, to ensure safety you would need to make sure both battery packs are charged to the same voltage before connecting them in parallel. One can argue with the BMS in play that you might have a lot of leeway in how different the voltages can be tolerated.
You really should not call this a parallel setup as that is not accurate. This is a dual battery system that can be switched on the fly between each. Does the smaller battery have enough capacity to not be over discharged? It would have to be using higher Amp cells than the standard pack.
Super useful 👌 after 2 ares of riding and if I like scooter and not that expensive for my Vsett8 is abaut 350€ I found out in Cehoslovakia I found solution they made for EU that cind of pakeging. And I low it. Small is best solution fir mine and its not small :) i think its range 20km only external+ from Vsett and 350€ is not litle but sels are from LG or Samung
Hello Falcon, you guys ROCK!!! I have a simple question can you parallel series wire 2 scooter controller positive and negative connections to the only 1 output from a battery if that battery (replacement) shares the same voltage ⚡️ as the original? ( Need new Dualtron battery 🔋 that originally has Dual outputs and a single input) thanks 😊
Shoot you got a weped if it was me and I had a weped, I wouldn't touch nothing on it, modified thought is no more at that level, the WEPED OR THE RION, ... ijs just an opinion
Why not simply connect both batteries in parallel instead? It would reduce the strain on the cells, keep the same voltage between both, provide a bit better range and offer stronger, more consistent performance across the board than this complicated solution. (With some diodes if the extra battery is not permanently connected to prevent one battery to charge the other at high current)
@@GFong There are plug and play devices available (but at a cost) if making such a thing is out of your ability/comfort zone. The DATEx2 Parallel Battery Adapter - Or Battery Blender in US, Is a prime example. It's not cheap, But design wise is the best imo. It uses XT60 sockets. And you can simply run 2 batteries of any AH or voltage and your controller though it with no hassle.
hey great video , WILL THIS WORK ON MY KAABO WOLF KING GT 72V the ato switching one. and will it drain from both batteries at the same time so I get less voltage sag
Was thinking the external battery is cheaper smaller y don't he get rid of original battery and replace with 3 of them new battery packs would that be possible
@@FalconpevSg thas not the point if the original battery OK or not I'm thinking Moore 3 of them instead of the original 1 would be 2x times the you could go ie distance and bit Moore power I'm saying as I have apollo ghost and maybe would like two travel 2 times the distance or use a lil of my power and no I'm going get where I'm going with out losing battery ie the faster I go the quicker the battery life so if you have 3 of them I'd be able 2 full power and still get where I need two as il have 2 times the battery life
@@FalconpevSg nono, I mean: Does it support regenerativ breaking? I think so because the relay doesn't care in which direction the current flows, am I right?
*Great video! Automatic SSR is out of stock? I have found on your website only with button. I wanna try to use on my honghao s12 / kugoo g-booster (48V and 20Ah internal battery). I wanna use with external 48V battery but maybe 15ah external battery*
This is what i want, having a reserve battery when your internal battery is low. will this work with 36v? thinking of doing this setup, i don't want to connect both , just want to have separate internal and use as reserve the external.
I wish y'all have a USA dealer who sells these scooters and xan to this for us because I'll buy one have it with a matching battery size and not worry about saving for a Dualtron I love the Zero X line but mines would have to come with a external battery
Okay so I have a 48v 13ah zero 9 scooter, am wondering if I can add a different branded 48v 30Ah lithium ion battery?? And which switch do I buy? The dual or single? As it only has rear wheel drive
You helped me a lot with this video,it is what i was looking for.My scooter though is a nanrobot d4+,will i have a problem installing it? I believe not.
I found this video looking to do the same on my Nanrobot D4+. I seen another guy do use a zero10 external on his D6+. So it should be doable. I definitely want to use the smart switch option.
Hi i wonder if , i have a kugoo kirin m4 pro and it has a 48v 18 ah can i add an a biger ah than the stock battery and charge them two batterys from same charge por, or i need to have same ah as the stock, will the charger burn if i have bigger ah than the stock ?
On your website description it says "A push button SPST switch is provided to turn on and off the solid state relay. When required to be connected to parallel batteries, you will need to use dual relays. " If I want to use the manual switch to switch between an internal and external battery like you showed in the video does that mean I need to get two of the relays? What does it mean I will need to use dual relays? Or can I just buy one of the manual solid state relays to achieve that?
Honestly this device isint really necessary. If you fully charge both batteries you can connect them with a simple pigtail permanently or if you want to keep the second battery separate to where you can disconnect it just plug it into the charger port on the scooter when the scooter and external batteries are both fully charged then they will drain evenly and you will actually get better distance than using a switching device.
Im trying to reduce voltage sag when I go full acceleration it goes from 65v to 60v. I want a external 15ah battery to help. Should I use a parallel switch or a parallel harness?
Can I connect the 52v35Ah battery to the ZERO 10X's 52v25Ah controller using a parallel battery solid state switch DC relay to extend the range? Shouldn't it exceed 25Ah? The built-in battery is 52v23Ah. If you do not reply firmly, you cannot purchase a sub-battery.
Hello sir I have iscoter with 36v 7.5 ah inside battery. My question is may I connect 3.6 20ah external battery in the scooter. If yes then should I need to upgrade firmware. If no then why? Please 🙏 your reply will be height appreciate. Thanks
You could just add an extra metal casing compartment on top of the foot rest section of scooter and replace the original battery with a larger battery that is double the size, however the stem length needs to be re-adjusted. I think this would be a much easier solution!
Not really. The metal casing compartment will have a lot of holes for which the water to get in. this is easier and more plug and play without getting rid of your original battery. You can still use your original battery with this parallel solution
@@FalconpevSg I understand your point, however if the original battery fails after long time use. And someone wanted to have a bigger battery than the original as well as comfortable seat, then my solution would work for long range commutes to outside of the city.
@@koochooloo007 that’s one of the options we considered in 2018 but it would be difficult to prevent water penetration once you added a spacer on top of the deck
So where do I get the cord? The button, cord or maybe a toggle switch even... Gives the playing field more room to play. I need another tutorial please sir..
how do you charge the second battery? i have a 52v 23amp internal and a 52v 18.2amp external battery, im gonna order the solid state switch, so how do i charge the spare battery?
When you charge both of the batteries, do you need to charge them separately ( disconnected) or it is okay to charged them while they are still connected?
I want to double the range on my gunai scooter, do I need to slap some sort of amperage regulator in place? Or should I just install a flipper switch to toggle between batteries and install some capacitors to handle the brief second when switching over?
Can somebody please answer this if you know for certain; Does this work with regenerative braking? All the solid state battery balancers I have looked at for e-bikes are described as explicitly not supporting regen. I require regen for my e-skateboard build, as it is the only stopping mechanism. I want dual removable batteries to enable instant spare swaps, and convenient charging routine, leaving my rather heavy, powerful board in my car while taking just the batteries upstairs to my 3rd floor apartment (with no elevator) for recharging.
I don't believe this will work with regen braking as I tried a similar system on my 60V batteries and saw 95V being fed back to the batteries during braking.
Do you plan to provide "charge controller"? That's a relay plus voltage comparator. Idea of using this to prevent battery from charging above 80%, thus prolonging battery life significantly.
@@FalconpevSg but charging to 100% percent puts more stress on battery cells, this leads to faster degradation. 500 cycles (like you mentioned in movie) means 18 months of daily 100-0% cycling or 5x more if cycling in 80-10% range.
I have fiido Q1 72V 1500watts with Battery 60V 12Ah , my question is can i combine it the original battery stock fiido 36V 10Ah using the Solid State Battery relay to make 72V ? 🥳🥳 thankz
Couldn’t we just swap out this small battery for the big battery and get more room in the deck? Or am I missing something. Or do we lose something in the process?
Ease of use. To swap out a battery, you need to undo the screws and take out the battery and put in the new battery...nobody wants to do that mid ride.
@@FalconpevSg Not what I am asking... That battery looks very small compared to what I have now. Can I just swap out this battery for old bigger battery? It will leave more room for other things.
Great solution ! I have a Techlife x7s with fault codes e00,e06. It cutsout completely when Im aceelarating. Do you have and idea what can Cause these errors? Thanks in advance
@@FalconpevSg im located in Sweden, MAlmö. Is the x7s same as the zero 10x ? Techlife is not responding on my calls nore emails, it broke down after 5weeks so kinda dissapointed with their service :/ thanks guys
@@eminentmindset9705 e06 is battery cutting off prematurely. You have to do 2 things for us. Do a full charge and let us know what is the voltage at the full charge. Try to replicate the cutting off and then note down the voltage when it cuts off. Let us know.
@@FalconpevSg thx for replying, the voltage is at 59,2 fully charged when after it cutsoff during hard acceleration the voltage just keep dropping to zero and it stays dead til i plug in the charger again. If the charger is plugged it stoping it from cutting off but then e00 fault comes on. Very confusing. I changed settings in the display then found a right settings and changed back. Thanks
How much is this expected to cost in USD’s ? And do you ship direct to the USA or do I have to purchase through REV RIDES ? I have the Zero 10x. There isn’t any degradation issue’s yet, but I’d like to have this switch just in case. Thanks
@@FalconpevSg I have the Jueshuai Scooter Battery:18650 lithium battery Motor: 3200W Battery capacity: 26AH Working Voltage: 60V Will your battery work for this scooter? i got it from aliexpress and want to increase the range more.
@@aysenvi9646 yes our battery would work. You can get the 60V 28Ah one here www.falconpev.com.sg/products/external-zero-10x-52v-23-8ah-battery?_pos=1&_sid=1458f368e&_ss=r
