Triple Your Super 73 ZG's Range: Step-by-Step Guide to Adding a Secondary Battery
HTML-код
- Опубликовано: 21 авг 2024
- I love my Super73 ZG ebike, but it's 8.7 ah battery is quite small and range limiting. In this video I add an additional 15ah battery to try and alleviate my range anxiety.
==
Get ready for an electrifying upgrade with the addition of a secondary battery to your Super 73 ZG! In this video, we'll guide you step by step on how to install a new 15-amp hour battery to the original 8.6-amp hour battery, both at 36 volts. While it's important to note that this will void your original manufacturer warranty, the added power and increased range will make it all worth it!
We'll start by removing screws and freeing the saddle, followed by mounting the battery and cutting away any cable ties that might be holding the cables. After that, we'll unscrew the top of the saddle to reveal the battery and controller inside. Plug in the cables and connect the batteries using a Y-connector to triple the range of your bike.
This is not just any ordinary upgrade, it's a thrilling journey to supercharge your ride! With our guidance and a few tools, you'll have your Super 73 ZG ready for a wild adventure. So buckle up and let's get started!

Great, thanks for this. My Super73 ZG has not been taking a charge so I’ve been wanting to get the seat apart for the best part of 12 months but not got round to it. (Hopefully the battery still has life in it after not taking a charge for nearly 2 years…) Had made a start but those cables seemed impossible to pull apart! Seeing your video gives me the confidence to crack on and pull it all apart. Thanks!
Wonderful instruction video.
Waaaasssy better than some one just commenting what they did to modify
Thanks man
Job done. Great Vid.👍🏽
Thanks
yeah this is what i was after nice one
Mate I just subbed, your videos are spot on what I was looking for. My wife has a ZG that she commutes on and I have recently got an e-bike with an absurdly large range (130 + miles) I was planning on upgrading the battery so we can ride together & your video has done all the hard work for me. All of your other vids are along the same line of mods we where thinking. I've noticed in a later video when you swap the controller out you have the fucking holy grail, fenders. Where did you snag those from? been looking everywhere. Currently contemplating trying to mod some other fat tire fenders.
It took me ages to find the fenders. I got lucky when someone I was talking to said that they had ordered their bike and fenders and then their bike arrived with fenders as well as an extra set. It was pure luck. Sorry man. I hope you enjoy the other videos too... Where are you based? Your name reminds me of the rozzers.
@@orange73 I see, up north near Manchester. lol it was a college nickname that stuck. gonna have a delve into your other vids later. I'm currently looking into swapping the chain for a belt drive. Because of the wifes posture she's forever fucking up shoes with chain grease.
@@ThePhilff I had a bike with a belt before. Ironically, I left it locked up at my house one weekend when I was visiting Manchester, and when I returned it was gone.
The thing I know about them though... You need a gap in your frame somewhere to fit them, because the belt cannot be unlinked. On my bike, which was a trek solo, the gap in the frame was down near the drop outs.
Good luck!
@@b-rockbeats4355 cheers bud, it's something to have think about for sure.
Next mod should be lights. Get some neons going.
Aight, I have got light mods in the pipeline. They are a lot more complex than this one though.
Thanks bro!
No problem!
have you had any issues with mounting the battery upside down? appreciate it saves you having to extend the anderson connectors?
No, none. It locks in fine.
Nice!
Thank you! Cheers!
Appreciate the videos mate, any idea where I could source the y cables, can't seem to find any on ebay or online? Cheers pal
Not sure where you will get them now, because I got mine about a year ago, but I do know this... If you get 3 red and 3 black Anderson powerpole connectors from Amazon or eBay, you can knock together a y cable yourself in about 5 minutes. Might be the quickest answer.
@@orange73 Cheers mate will give it a go
the music lol
Just relax 😅👍
Thanks for the video, I’d like to do the same to my Z3 . Can you add eBay links to all the parts I need ? Cheers 👍🏽
I thought a z3 was a BMW 🤣.. you have to chose the parts that fit your bike, so I wouldn't want to tell you the wrong thing!
@@orange73 lol I meant a ZG mate
ah no worries...
Ok, so the place i bought from that I showed in the video doesn't seem to have stock now... ebay links expire anyway... so I have updated the description with some search terms that should help...
@@orange73 perfect thanks ! 👍🏽
@@BeKindMofos I have more mods to come too, including motorbike headlamps
Hi there! I just bought a 36v 13ah battery and the cable to connect both batteries. Can I use both batteries at the same time? Or is it better to use one at a time? What’s you recommendation? Thanks!
Use both at same time is ok. Charge both with same charger. They become like one larger 36v battery.
Do you unplug the Y cable if you want to charge the batteries (because you are charging them independently wouldnt harm the other battery if they are still connect with the Y cable)? With this setup do I need to check everytime before riding that both of the batteries are fully charged so that their voltage are the same? Thanks in advance man!🤘🏽
I actually just use the original charger which chargers both batteries without issues.
@@orange73 nice man! So do I need to make sure that they are both fully charged before plugging in the Y cable? Which battery do you switch on first or doesn’t it matter?
@@d.0202 I did charge mine first, but I'm not sure how much it matters. I switch both batteries on before I power up the controller from the handle bars. If you think about it, what you have is a bunch of 18650's. An 18650 should be 3.6v and so you have groups of 10 of them in series in your battery pack. The groups are then aligned in parallel. All you are really doing is adding extra packs in parallel. I.e. the original battery might be 20*18650 in 2 groups of 10, and I added another 4 groups of 10.
In short, if you charge together, and you discharge together, they should all level out. At least that is my understanding.
You can, of course, switch each battery on and use it independently, if you wish .. like run on the big added battery, until it runs out, then power everything down, switch off that battery and switch the other on, and fire it all up again. I think if you do that though, the bike gets slower as it chews through the battery, so probably best to run both.
@@orange73 I really appreciate you! Thanks I understand it now. I will do the same setup🙏🏽🙏🏽👍🏽👍🏽
@@d.0202 honestly, it's all an experiment. Whatever suits you best, but don't mix voltages.
I'm installing the same battery on my ZG. I can't see how you putted the connecters and wire through the hole in the black plastic.
How do I open that hole? It's closed with some sort of lid (edit: grommet). Or did you bore that hole out?
Did you take the grommet out?
@@orange73
Grommet is the word, thanks.
It seems stuck. How do I get it out, just pull hard?
Hello i see 36v 50ah battery on aliexpress anyone know if its legit?
Having the y connectors over heat the controller or running them at the same time over heat it
no, no heat problems at all. You are not drawing any more current than you would do from a single battery. You are using the same amount of power, so no extra heat is made.
hi mate, can you make it so that it only works on the removable battery? So kinda make it like a ZX
If you only connect one battery, you will only have one battery connected, but it will work.
So I have the Z1 arriving next week, which seems to be the US version of the ZG. Any idea if they use the same Y cables? I’d like to try this. Also, do you run both batteries at the same time, or one at a time? Thanks
Sorry mate, Z1's are not available in the UK so I have never seen one, and can't comment on their config.
I do run both batteries at the same time though. I.e. in parallel.
@@orange73 appreciate the response! Your hack is super clean. Will do more research for when mine arrives and see what I got.
@@trendkill518 look for a guy @Runplayback here on youtube... he has done lots of Z1 mods.
i own a Super73 Z1. same bike (specs) just branded with different name in different market.
if you mod dual battery, no you’re not running both batteries at same time. you’re basically switching Andersen connectors, from batteryA to controller to batteryB to controller. plan to adjust for wire location and accessibility too.
my first mod was keeping the original battery under seat (36v 11.5ah) and adding external 36v 20ah battery, like one in video. in my case, the 36v 20ah external battery gave me enough power to get through most of my “normal” riding day. got rid of OEM controller, removed OEM battery too, upgraded controller to 48v controller and used battery space under seat to install 24v power pack for custom light system. Upgraded battery to 48v20ah.
ALWAYS go for battery with the most amp-hours you can afford… you’ll thank yourself later.
ebikes, imo, are made to be customized.
Mod on!

@@robertmotion very nice! I will definitely add mods, mostly for range, but should be fun! 🙏
Why does it need t to be 36v? Can't you just use a more powerful one?
If you use a more powerful one, it cannot be used with the original. Also the maximum rating for the controller is 36v
Hey so does this mean you would have to charge both batteries 7:47
Adding batteries in parallel means you are essentially extending them. 2x 36v in parallel can be charged by one charger. If you want to charge them separately, disconnected one first.
I’m in the US with a ZX. Does this apply?
Never been to the US. Never tried it on a ZX.
Having said that, battery technology is similar, so the theory should be similar, I just can't give you specifics.
where can you place the battery when you have the fender set installed.
I think in the same place. I fitted fenders myself in another video,but I didn't fit the one on the bottle mounts. I'd say you can just use longer screws though
@@orange73 oke thx
do you charge both batterys at the same time with 2 chargers ?
When you add batteries in parallel like this, they effectively become one bigger battery of the same voltage. As such, i just use one charger, but for longer.
Is there anyway I can communicate with you about installing 2 batteries for my electric bike?
You just have ;)
Please understand though, I have only ever put 2 batteries on this ebike!
@@orange73 I kinda wanted you to see if you could tell me which wire from my controller is connected to the battery. My controller looks similar to this one from the video.
anyone know where i can get a new seat ?
side note : i have a z miami not this model here
This may seem like a stupid question but do both batteries have to be charged separately or do they behave as one ? i.e. charge the stock battery and once full, it then charges the new additional one ?
I charge them both on their original chargers.
hey, im 190cm tall u think this bike is too small for me?
I'm 6ft on the dot and it's fine for me. Best thing to do is to test ride it. From what I have seen, the new ZX is a bit higher of the ground, bit it doesn't come in excellent orange.
Does this also increase the speed? If so how much?
Not really. Think of it like expanding your fuel tank, rather than tuning your engine ;)
@@orange73ok thank you
@@orange73 if I were to charge the batteries after a day of riding do I only have to charge one or both
@@flanz3366 With a parallel battery connection the capacity will increase, however the battery voltage will remain the same. Batteries connected in parallel must be of the same voltage and can be charged as a single battery pack.
It’s the same make bespov but just 48v 1000w 13ah
To go 48v you would have to swap it all to 48v... That means upgrading the controller as well as both batteries...
I'm going to be doing a controller update video soon... On the new controller I ordered you can use either 36v or 48v because it is reconfigurable. Both batteries have to be the same though, regardlesa
Thank you for your help can’t wait to watch your next video
@@tarikbarak288 I am just waiting on my parts to arrive.. more to come!
Hi mate I’ve just looked at the description of my super 73 zx and it’s actually a 48v battery
@@tarikbarak288 my video is for a zg, not a zx, or a z1... I haven't seen either of the other bikes, so it wouldn't be right of me to pretend I know about them.
General rule of thumb though...When two or more batteries are placed in parallel, the voltage in the circuit is the same as each individual battery. That is two, three, four or more 48v volt batteries in parallel will produce a voltage of 48v Volts! This is why you don't mix voltages.
Was looking to add this to my bike does it have to be 36v ?
What alternative where you thinking?
Battery for ebike can be anywhere from 36v to 52v, and in some cases 72v.
Z1/ZG OEM controller is 36v, 11.5ah (or something super anemic).
Modding your battery to anything other than 36v, you gon need to upgrade from OEM controller to one that matches battery power. 48v battery, 48v controller, etc.
ALWAYS purchase max amp-hour battery you can afford (or save up for) …. you’ll thank yourself later.

Where do you get that extra y connecter
Because I can’t find exactly that y connecter that you haven
@@noahvervoort3423 do a search on ebay for "powerpole y cable" 😀
@@orange73 thx bro
@@noahvervoort3423 np
@@orange73 I can’t find it
Does this work for the z1
ZG is the European equivalent of the US Z1. Don’t know what the ‘actual’ difference is but they are probably more or less exactly the same just with a speed limit on the EU version.
Goed Idea Bad Video😅
I love getting constructive criticism from a thumb in a hat.❤️
Its a good video
