Ahh, thanks!
The ones I use are these weird blue ones I've never actually seen used before, they look like these - http://www.dhgate.com/product/dhgate...FePHtAodQy4APg but I might look into some of those XT90s - the reason I ask about anything going wrong is because my battery sparked something chronic when I was plugging it in the last time I used it, almost as if it was shorting out (but it wasn't from what I can see) - like, rapid bright white flashes on the contacts in the connector (didn't have a link at that point) and the wiring's insulation all melted together/unsoldered itself - The only thing that changed for it to spark as intensely as that was that I'd clipped the wires to one of the ESCs, which might have caused it but naturally I'm a bit cautious now!

I'll definitely look into a spark connector though at some point too, looking into those higher cell LiPos, familiarising myself with it early on can only be a good thing! Thanks for the help!
