Tongsheng TSDZ2: Hardware differences between various models?

[zoki]

Hi,

I know that there are hardware differences between Bafang BBS01, BBS03, and BBSHD models and they also have different prices. Tongsheng TSDZ2 models are all looking the same and have the same price on eBay.
I am wondering what is the real difference between various TSDZ2 models other than the label? Can I transform the 250W 36V model to 500W or even 750W 48V model within software settings? Can I use a 48V battery on the 250W model to get more powerful engine without any additional changes?

Best regards, Zoran

There are only two motor versions, 36 and 48v, the difference is they are wound differently. (4000rpm at 36v and 4000rpm at 48v) The controllers are all the same and support 36-52v. You can search the long thread with all the answers. (There's also a coaster brake version, that's different)

I found a long thread with a lot of interesting information.

Thanks
