I live in Toronto where it gets really cold in the winter. I don't have a garage or storage so I can bring the batteries inside my home to keep them at a regular temperature. How can I keep the ECU battery charged? Is there a way to plug the charger in the bike to maintain the ECU? any suggestions that you have would be appreciated. I do use the bike in the winter but I noticed that the ECU drains really fast.
Yes you can bring them inside. There’s no direct way to charge the ECU that I know of outside of plugging the charger into the bike. I don’t know whether the batteries need to be in while charging this way to affect the ECU charging. You could email technical@niu.com to ask them directly. Good luck!
I went to a NIU dealer a few months ago and I remember that the salesperson told me something about they knowing if the battery is not properly taken care of and that the warranty could be voided by NIU since they had ways (internet) to monitor the use.
Great video, thanks! I'm getting one this Friday at the Vespa dealer in Vancouver, can't believe how amazing this vehicle is, hard to find any glitch on the bike. I'm probably going to ride it from March to November, I have a car as well. I'm getting the top of the line on 60 V 35 amps, might as well, NQi Gt, black with red strips. Oh, is there anywhere to store the charger IN the scooter if I'm going on a trip and maybe want to charge it somewhere else? Thanks again..
Congrats on getting the new scooter! And sorry for the delay - your comment got held up in a filter for some reason. No place to hold a charger unless you get the added storage box on the back of the scooter which is a good idea considering the lack of storage options. Have fun up there! And check out The Shameful Tiki Room!
Hello, Vespa of Portland! Love my new Niu MQI+ Sport and it's getting LOTS of attention from neighbors and co-workers here in Central Oregon! To clarify: As I won't be riding my scooter during the colder months, I plan to bring the battery inside. But what about the scooter itself? Is it OK to leave it out in the garage (sans battery) when the temps drop to below 32 F? And would you recommend a cover? Thank you!
What´s happening if the ECU battery is completly drained out if I unplug the main battery? Can I just plug in the main battery and go for a ride instantly? Or do I have to wait for the ECU to charge up for a bit?
May have to wait a bit for it to charge up. Ideally you’re plugged directly into the bike when charging if that ECU battery is dead. Passes the charge on to it instead of just the larger batteries.
Hi there. Lots of good info here about batteries, but my question is should I have a top value to charge to as well? I.e not charge them to 100% for longevity, like I'm told to not do with my car Li-ion battery? (recommended 80% to limit dendrite formation). Thanks!
20-80% is generally the ideal charge for lithium ion batteries but we have never been instructed to tell people not to take them to 100%. You should be fine and can expect about 1200 charge cycles or the rough equivalent of 5 years before the battery is at 80% of charge.
do you know if there are any table showing the error codes present in battery when it blinks in error? I saw my battery blinking in a patern frequency, but I cannot find anything in service manual...
Best bet is to email technical@NIU.com with your VIN and a description of what you’re seeing. They’ll be able to check out your scooter remotely. And then take it in to your local dealer/service center for repair if needed. Sometimes they just run over the air updates and it fixes an issue. Good luck!
Can you comment on the cheap metal used on chinese brand? Many review say that after 2-3 years in four season countries the scooter rusts out pretty quickly. also can you comment on the sturdiness of the front lift?
Can’t comment from personal experience on the metal over time since we’ve only had NIU in out market for about 3 years now. In places with higher humidity or salt content in the air, metal is going to rust quicker. Many scooters, regardless of country origin, aren’t well painted or sealed and can see rust in these environments. Front shock seems standard for a scooter. Thanks for watching!
Yeah, dont deep discharge these batteries. My UQI pro was depleted down to 8% because i had one delivery more than expected. Aside from me having to go 20km/h on the road, it took forever to recharge to 50%. Im talkin 3hrs.
Charging up to 100% once in a while is good practice to balance out cells, but not all the time. If possible, try to stay between 20-80% under normal use If you know you need the extra range, sure charge up to the brim
Isn't the battery excess-discharge issue something the BMS should take care of? It looks like NIU is already pretty sophisticated in terms of software and so on.
Good question. The BMS does not seem to stop the battery from charging (hence why they say to remove it from the charger by 12hrs) and the draw for over the air updates will continue without the BMS stopping it to conserve battery - from what we’ve seen at least. A software update could probably fix both of this scenarios but it has yet to be seen. Thanks for watching.
@@VespaPortland Any rough estimate of the price? My Local dealer here cannot help to get me 35ah, Mostly available locally is just 26ah Eve Cells which is really poor in quality, Even 35ah source out directly from CN. Unlike Panasonic cells on 35ah. I hope you can help.
I wouldn’t worry about that. If you have any background and coding, you would know that they would need to program the app to randomly assign a battery to a place. And that wouldn’t make any sense.
Unseen battery isage is a bad design. There should be a light diode showing it is on in some way. It should be obvious how to turn that off. Not only written in the manual.
Don’t let the batteries go completely flat as you then can’t get them to charge. A complete pain in the arse. Had to pay £200. Get them. Restarted The bike was only 300 miles on the clock when I let it go flat. Now it’s done 600 miles and it’s gone completely flat again and the batteries won’t charge again. Absolutely rubbish By the way I bought 2. New had the same problems with both. Complete crap
That can happen. The owner either needs to ride the scooter regularly or follow the storage procedures. Same kind of thing happens with a carbureted gas powered scooter. Good luck.
It’s not like they did it to punish you. That’s the architecture of the electronics at this point. Eventually batteries just don’t come back. Same with traditional lead acid.
