Any luck with Aliexpress?
You shouldn't have to do this.
The seller CHAMRIDER is sending a whole new battery.
Now the issue with the 60% charging on the display is because the seller on aliexpress put a 52v controller on my 48v casing. Can you believe that?!
I live in venezuela so returning things is very expensive by dhl. So... I'm screwed on that end.
I'm not familiar with that seller but that is the risk of Aliexpress.
Well since it is there mistake maybe you can ask Aliexpress, not the seller for a partial refund.
Is your dispute window closed?
Also is there any type of warranty described by the seller on this item?
And if you paid by credit card, here we can dispute charges for items that are not as described, defective or incorrect with the credit card company by calling the number on the card. This is a service of Mastercard, Visa etc..
I'd also suggest with this type of product that there are sellers on Aliexpress that service in the USA. That may be a cheaper alternative going forward for service
This is the seller that I used Greenergy and they were pretty good. They ship and service out of USA... I don't know if that is an option for you.
Over Luna I think I would go with EM3EV or California eBike if I didn't want to use Aliexpress... But again you'd have to see what is workable to Venezuela.
Good luck with it and be careful working with the battery
I bought the motor from Greenergy but from their aliexpress store. They screwed up the motor controller! LOL.
The 07 overvolt error from controllers that 48V nominal limited should be out of the supply chain, but there are still 48V versions being sold. Bafang has never given a dealer anyway to link firmware versions to serial numbers, so we rely on experience and previous support issues to assist customers.On the older BBS motors, the operatiing battery voltage could be set by the user, using a Windows PC and programming cable. Some ebike forums report that Bafang was moving away from the 52V option and had changed the firmware to lock it in at 48V.
This situation sounds like it could happen with older motors, but not with newer ones.
So they are sending you a 52V battery?
