Receiver my FMA 10s Lithium charger today, and WOW, what a great piece of equipment!

Anyhow, charged up my finished (now shrink wrapped) 4s A123 pack. Worked AWESOME. Charger displayed all 4 cells progress and independent voltage. I haven't tried the PC monitoring software yet, but I plan to.
Plugged in the pack and did some more testing infront of the house. I thought a dead battery pack hard punch! Jeeze, this thing has enough power to shred the tires on any surface and then some.
I temped the ESC and motor with just a few minutes of LIGHT testing. ESC was up to 120, motor was 88, batteries were not much warmer than the air. But with some feeling around on the truck I think I might have found the culprit. Two of the Three motor wires were warm...what does that tell you? I checked the plugs and as it turns out one of the plugs is damaged, the plug that was connected to the coolest wire to be exact. Wasn't my solder connection, the actual plug is damged, one of the spring teeth was barely hanging on there. Luckily, I ordered some more sets of plug from Tower this weekend and they got here today! Stay tuned....
