How do you know when the power supply is getting low in the Joysway transmitter?
Mine beeps for no apparent reason as the batteries are good.
Is their a minimum voltage as Joysway has said that rechargeable batteries should not be used.?

Presumably when the transmitter tells you so!
As far as I am aware, virtually every piece of electronic equipment has a minimum voltage. 4 NiMh cells have a nominal voltage of 4.8 volts and 4 Alkaline dry cells have nominal voltage of 6 volts, If Joysway say that rechargeables should not be used, one can probably assume that they consider the voltage from rechargeables to be inadequate.
I would suggest you take the batteries out of the transmitter and put them in another of your Joysway transmitters. If that beeps too, then I think it fair to assume the batteries need replacing.
For the cost of a set of batteries and the length of time they last, I would just change them and get on with sailing. You could, of course, just keep using them and see how long it takes to sail off into the sunset under its own control and then you would know for sure whether the beeping was relevant or not!

I've used rechargeable batteries in the Joysway transmitter with no problems. Had no range issues either.
I used 2900Mah cells from Vapextech, don't know how long they will last per charge , but I suspect you would easily get a full day's sailing.
I normally use a Futaba T6J set for all my boats and the same batteries would give me around 1.5 days racing, unlike the original Spektrum DX6 which needed two sets a day!

John.
Interesting, your experience of the original Spektrum DX6 and how heavy it was on batteries. I use the current DX6i and it is so light on batteries that I haven't bothered to install rechargeable, just using alkaline. The latest only use 4 cells rather than the 8 used in older transmitters and they last for a minimum of 20 hours of on time, at a guess, probably even longer.
