    Heavy Duty Remote On/Off Switch

    Has anyone experienced lipo drain if lipo is left wired to the Remote On/Off switch from Drydocks even when remote is turned off? I left it wired for two days and my lipo drained below the rechargeable rate minimum. I was able to charge at a lower rate but it is no longer balanced. I realize it should not be left wired when not in use, but wondering what I could wire inbetween the remote receiver and the lipo to stop the discharge.

        I ran the red & black wires to lipo, the other black wire and the white wires to the ESC

          Is that a remote on/off with a key fob? if so the battery always powers the receiver in the switch-although it will use very little power...it should be disconnected at the end of the day. If it doesn't have a key fob transmitter...then nevermind -BG

              All I could say about anything you could put in between the the remote and the battery is an open circuit...considering the low amperage drawn by the remote switch,you could install a normally closed magnetic reed switch to supply the power for the receiver only( not the supply for the load) At the end of the day you could drop a magnet next to the switch capsule and open that circuit. Kind of redundant though -I would just disconnect the battery..especially a lipo-which needs to be charged or discharged back to storage charge levels when not in use...and you DON'T want to do that in the sub (the model submarine does not make for a good fireproof charging container) -also note that a magnetic reed switch is good for only a very low amperage.

                  Of course it drains the battery. It needs to listen for signal, and therefore needs to be "awake". Current draw is miniscule... something like 20 or 30 mA, but it's there.

                    Don't look at the remote switch as an on-off switch , consider it an arm-disarm switch...

                        That is the best description I have heard for this. I will be using that to explain these!
                        If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.
