Morning all

Just bought a new Argos drill for my FW, and the 550S inside appears to be 10.8V, rather than the advertised 12V. My question is, if I run this to drive my left wheel, but still use a 12V version on the right; will the bot still move in a straight line?

I have 4S lipos, so over-volting shouldn't be a problem; but it might be for those with 5S.
