Title: Voltage balancer / equaliser
Post by: sailorboy61 on December 16, 2010, 04:36:56 pm: I intend to use two batteries to drive a pair of motors and am thinking it would be best to have some means to balance the voltage as they run down at different rates.
I recall seeing somewhere an electronic balancer, perhaps from Action? I am thinking both batteries into the leveller, then presumable I can take two identical outputs to a twin ESC/Motor set up.

Anyone have any experience, ideas comments?

Thanks
