Going to post a pic soon, but I am still in awe at how stupid I could be.
Just balance charged a brand new 7200mAh 4s brick, was in a rush to get out an bash a bit before the sun went down. Started to see some sparks intermittedly? Yeah, forgot to secure the balance leads, an it got munched on by the spur an pinion an ripped out of the battery. The remains of those wires were touching when bottoming on the chassis. Good thing it wasn't constant, or I could have seen the entire rig up in flames.
Still use the battery, though I had to CAREFULLY isolate the balance wires, heat-shrink them individualy, then all together, an use some Kapton tape to secure the mess to the inside of the case of the battery. I can still charge it, but it takes much longer, as I can no longer balance the cells, so have to charge at a much lower amperage.
D'OH!
Upadate: After the last run, I really really don't trust a mangled battery left in the house, even if in a lipo bag inside a .50Cal box. So...what better way to sight in my brand new Walther PPQ? Heh...yeah...thems lipos blows up reeeaaalll good-like.
