Ziiten Posted October 22, 2018 Share Posted October 22, 2018 Noticed that the Z10 is now available for preorder 1450€ (inc. 131€ shipping to Finland). That's about -300€ what I paid. 1 Quote Link to comment Share on other sites More sharing options...

Ziiten Posted October 22, 2018 Share Posted October 22, 2018 That was not my intention, to cause late buyers remorse in Z10 owners - I sure don't have any. It was just to give a heads up for anyone considering to buy one but who thought it was too expensive at 1800€. Quote Link to comment Share on other sites More sharing options...

So far i have seen only fake offers or for 1400 Euro You have been able to get Z6 (also not local offers) Quote Link to comment Share on other sites More sharing options...

Z6 was quoted at 969€ + shipping (~130€). I think this was a special offer related to the 11.11., which is some sort of marketing campaign day in AliExpress. The Z10 will most likely never be offered locally, here at least. Too much power for any street legal use. No importer/reseller would risk selling such a device as they would be responsible for not putting out anything that doesn't conform with legislation.

You need to fix that. you can try opening the wheel and charging each battery separately and then connecting both batteries again. Quote Link to comment Share on other sites More sharing options...
FreeRide Posted October 29, 2018 Share Posted October 29, 2018 Did you do a lot of downhill riding? Just curious if you have any information on how it came about. Someone else had this problem also. The BMS may have tripped on one battery during riding also. Quote Link to comment Share on other sites More sharing options...

Not sure why one cell group would be unbalanced, but I would slowly charge each battery pack separately. First try to find out which one is battery 1 with the bad group. Search the forum, someone else had this issue, and I can't remember if they were able to restore the battery or if it needed replacement.

Marty Backe Posted October 29, 2018 Share Posted October 29, 2018 38 minutes ago, RoberAce said: What means? What I need to do? Were you running for a extended period of time downhill? The Z10 only regeneratively charges one of the two batteries. So if you do a lot of downhill riding than the voltage differential between the batteries can get large (I've seen as much as 25% on my Z10). Recharging the wheel should fix it. 2 Quote Link to comment Share on other sites More sharing options...
Nic Posted October 30, 2018 Share Posted October 30, 2018 (edited) Check the above topic as it is for the same error as you describe. You may have a faulty cell in battery pack1 as your message says. If one cell is at a lower voltage than the others (that are in series with it), then that cell needs to be replaced because it is now showing a different capacity to the other cells in the group, which means it will charge faster and drain faster and this can result in fires when over-charged. This is why the BMS is warning you. In an ideal battery pack all series-connected cells should have identical capacity so that they charge and discharge at the same rate and no single cell becomes damaged due to being over-charged and over-discharged. This is why we have BMS, but BMS cannot fix capacity loss issue for a single cell in a group. The best thing you can do to keep your battery healthy is to never drain it down too far and never charge it all the way up. Doing this prevents damage to cells that have slightly different capacities because when cells are connected in series they all receive the same amount of charge and some cells may reach their max/min voltage sooner than others.

Assuming that there isn't actually a fault in the wheel, plugging in the charger will equalize the batteries. Guaranteed. No need to ride the wheel. 2 Quote Link to comment Share on other sites More sharing options...

Yes it is NINEbattery v1.5., whose author joined russian telegram z10 group, and said that he add Ninebot Z support there and put APK for us. We use it without any problems. By the way, it seems he released 1.6 version, which I guess also should support z10 I think that RoberAce's warning message means that some cell in battery pack 1 has balancing problem, not difference between battery pack 1 and 2, Z10 can work with that without any issues.

This app show in details voltages for each of 14 group of cells for both of batteries - very useful diagnostic application. I have used it without issues. If still afraid - take some old android phone without crucial data on it... Edited November 1, 2018 by Lukasz 1 1 Quote Link to comment Share on other sites More sharing options...
