Hello,
didn't found such topic, so will ask here (already done on RCG but...).
I would like to use AQ6 with 6S batteries. If i understood correctly, onboard SMPS are limited to 4S only (16.8V fully charged, and they're rated only up to 18V). So, for anything above 4S we need different solution, right?
For now i think about such workaround - ESC's (--> motors) are powered by 6S flight battery. Middle wire (5V) from ESC SBEC is removed.
Everything else is powered by separate 3S battery (VTX, OSD, gimbal, AQ6). This would allow to use copter without serious modifications.
Another alternative is to use one powerfull SMPS, 6S -> 12.5V for everything on board. This would eliminate needs for separate flight battery, but noise, reliability and other factor remains...
The problem here - can't monitor flight pack, because AQ6 is not rated for this. What's proper solution? Add voltage divider (let's say 2:1 and configure 6S pack as 3S pack)? Fully charged 6S pack is ~25.2V (4.2*6), maybe i can get around this problem by changing voltage dividers on board (i have both, rev0 and rev1 boards)?
How others are solving this problem with > 4S setups?
