ahh k. have you tried another anti spark plug for the loop?
The spark wonât damage other components, it will just wear out your loop key over time. If all your wiring is correct then it could be a dodgy loop key.

I thought this wiring was a good idea. I will replace the xt90-s with a new one and retest it. Back to my questions:
- Do you have a better wiring i could test? (maybe i change the XT90-S with a normal XT90 and splice a new XT90-S into negative ?
- Faulty XT90-S??
- Did i plug it in too fast?
If the xt90s resistor blew, there was obviously an overcurrent. There must be a short somewhere in your system. You cannot have anything plugged into the charge or balance connections when you insert the loop key. You need to re-check if your wiring corrsponds to the schematic. Perhaps you can draw up a schematic of precisely how youâve rigged it together.
1.) This is as far as I can see the best or only wiring for this situation. (adding more loop keys would be pointless) 2.) It is now. 3.) No.
All that complicated wiring. Why not just use the xt90s plug as a plug?
Charging or turning on or of
@hummie I think you missed the point. its so that you can charge as 6S and discharge as 12S and its not really that complicated.
Ok thatâs the point.
I have the same problem since I also have a vesc and want to use 12s. 12s chargers are pretty much non-existent but the set-up I use now Im really happy with as it seems the simplest, least amount of plugging and unplugging, and the cheapest. I use a Meanwell bulk charger and wire in a wattmeter and use a couple 15$ balancers at the same time. I hate plugging and unplugging balance plugs into chargers. They always get stuck and require a lot of force. These little balancers are really easy to put plugs in or out of, or even just lay them just touching. UploadingâŚ
I can charge at 400watts.
If anyone is nyerested in my Icharger that does 8s Iâm getting rid of it cheap. Make me an offer
Today I rechecked my wiring and did find the mistake⌠I just soldered it like the wiring you have Seen before. Exactly like the wiring diagramm and that was my mistake.
In that wiring the polarity of the xt90-s loop key will be wrong! In the diagramm there is a Red positive cable to the left and the black negative on the right. But when we Look at the Battery cables they go the other way to the Esc⌠So i changed the polarity and blow my xt90-s. Thanks for the Input! I really appreciate this forum

to be fair, the diagram doesnât really show polarity of the XT connectors but just a box which represents them.
having said that Iâm also surprised that it matters. if you were connecting a battery to a load then the polarity is important, but a loop key shouldnât really matter about polarity.
either way its good that you have sorted out the problem.
