I have a couple of Turnigy Nano-tech 4S 5000mAh Lipos which at full charge are outputting 16.5v (according to DVM).
My jDrones 30A ESC on the label indicate that they are rated at 6v - 16v, however the sales literature states they are suitable for 2s - 4s Lipos.
Obviously with a 4S I was expecting the voltage to be 14.8v.
At full charge, could this extra 1.7v cause issues with the ESCs ?
Many thanks,
Steve

14.8V is the nominal value of your typical 4 cell LiPo. If you packs are reaching 16.8 Volts after charging you may want to decrease your cutoff voltage on your charger. Some believe that charging your LiPos' to the max actually decreases their lifespan. Personally I don't think this poses any real threat to your ESC. This is the case with just about every 4 cell LiPo and ESC on the market. Just fly and have fun:)
A 4S Lipo will typically (but nor always) output 16.8V when fully charged, so I suspect whoever wrote the label is just being a bit lazy and missed the .8 off the label. If it's rated for 4S, it should certainly be able to take 16.5V.
I haven't tried this on this particular ESC but 4S = 16.8V and Jani and the crew know this!
