I have just installed a BBS01-350W on my MTB, and thought it was in 36V, as advertised by the vendor (Eunorau on Aliexpress). Until now I am using 36V batteries, and it works well.
But I've check the display (TFT 850), and the voltage of the battery appears to be adjustable : 24, 36, or 48V (or "UBE", I don't know what it means).
And the factory setting is 48V
. Does it mean that the controller of the new BBS01 is made to run in 48V ? Or can accept batteries from 24 to 48V ?
If yes, is it safe to use a 13S Li-ion battery (54.6V at full charge), or is it better to stick to 11 or 12S (46.2 and 50.4 V at full charge) ?
PS : if anybody has some documentation from Bafang, I will appreciate
