Is it safe to power the Pro power supply with 29.6V (8S)? Yes I see the max input is listed at 26V and I can do math :-). I'm hoping that maybe the unit has a bit of capacity over the listed limit.
Given that 26V is so close to 8S it seems odd that the board was designed with this limit rather than just a bit more to meet a common configuration. If one has 8S power onbaord one could just tap right in, instead of installing even more power circuitry to step down to 26V or lower.
Hello, Pro board can recieve no more than 26V http://ybex.com/d/ndjaz1zw39jifw8mi47tfwrlgem4657fepcmyfi2.html Fully charged 8S Li-ion or Li-pol battery has 33.6V (4.2*8) Pro board power board rated for 6S battery (25.2V), reserve up to 26V is indicated as guaranteed. The controller isn't designed for a higher supply voltage. When you calculating, you don't take into account voltage peaks that may occur when the controller is turned on and off.
