The v balancer has a special harness that plugs into the 2 main 4mm plugs on the trakpower lipo. It also has a a 2mm plug to connect to the balance port. The reg v balancer and the car version are the same save for different colors. Most other flightpower packs have a std balance plug that is the same as thunderpower uses.

Check out the pic, the larger red and black blocks with the male 4mm bullet connectors, also have a female 4mm for the balancer outputs to plug in. The pic shows it already plugged in, but you can buy the adapter seperately, and it will fit a lba balancer with some wiring mods.
