Good day,
right at the beginning I have to say that I am completely new in this issue, I only have some theoretical knowledge, I am embarking on the first construction. But first I always try to solve the problem myself, but now I don't know what to do, I'm in a dead end, so please ask for advice. I have this version of VESC 75 300 R2.
Probably totally stupid question for you - my VESC has three inputs on the battery - does the voltage add up on all three pairs of leads(for example, one 20V battery on each pair of leads, total voltage 60V), or should could there be a total voltage 60V on each pair of leads(for example, one 60V battery on each pair of lead, or one 60V battery connected to all three connections)?
Thanks...
The three battery inputs are in parallel. If you want to connect multiple batteries at the same time they all need to be at exactly the same voltage.
Be careful, this is a fake device and not official hardware. Where did you get this from?
