It’s a tough decision. On one hand it would be great to be able to simply plug in the correct charger. On the other hand, if the wrong charger gets plugged in you damage an expensive battery, at best.
If it were me, I’d clip the vex connector off of the vex and install a different one. That way there’s almost no chance the wrong charger gets plugged in.
Yeah, you know what charger is supposed to be used but that one trip to LOTW and you are 8 beers in and your buddy decides to do you a favor and charge it up with his charger, that’s when problems occur.
