Hello, I, like many others use one of these cheap buzzers to monitor my lipos while I ride. I was wondering if it would be possible to add a switch to this, so that I could keep it connected at all times.
Also, for a loop key like the one below, why is it that the side with the exposed bullet connectors (female connector) is attached to the board? Isn’t this a safety hazard if someone were to put their finger there and connect the circuit? Feeling 20v or more doesn’t seem healthy.
For the Lipo saver you will need to attaché and extra jxt terminal to conect the Lipo saver and still have a balance port for your charger, after this just need to solder a on/off switch in the negative cable of the jxt terminal that the Lipo saver is conected.
For the loopkey, well its easier to make the loopkey like this and not the other way around. Ofc you would like to add some protective tape / cover around it. Neverthless you can’t get electrical shock with just touch bare positive / negative lead only as your body doesn’t complete the circuit. (remember that loop key is only attached to positive / negative side only!)
Also, the reason for the loop key is to have it more hidden within the enclosure. If you put the male end on your board, then it will either have to stick out from the enclosure, or be mounted perfectly to allow the other xt90 to slide over it without interfering with the enclosure.
cool just wanted to be sure, normally people switch positive, but in this case switching negative makes sense.
Just to verify, fuses go on the positive power lead (connecting the battery to the esc) and a 60a fuse should be fine for a 6s board with a 1:5.5 reduction and 8in wheels?
