Hi
I didnt bother with Atomic Carbon, more Money
I run the Trakpower 4900 and all i did was stick velco onto the battey strap and lipo and on the bottom of the undertray where you glue the carbon blocks onto the lipos (no good if you want to sell the lipos again) and onto the bottom side of the lipo.
The lipos didnt move at all during the race!!!!!!!!
For the connections, all i did was make a Corally conection coming out and then going into a Dean, alot easier to get the battery connected up
Hope this has helped
