Notorious Cooling fans power source..

On dual battery set-up, I heard folks saying that powering a aux fan with the balance port can cause an un even draw…. Would it damage the battery if the balance ports were wired in parallel to power the auxiliary fans???

What about 1 fan per batt?

That is a thought, but I am only going to run 1 40mm fan, that moves about 22 cfm

I've done it. 3s and 4s. Instead of using another battery. Haven't had a issue yet. I noticed maybe .3 of a difference. But I'm also using two 40mm fans that pull a lot of air.. along with I don't run my batteries down to lvc.

Would the uneven draw be an issue if you set your LVC higher? That way, your batts wouldn't drain below minimum.
