So i am looking to do some new leeds on my charger and was wonder can the balance leeds be about a foot and a half long? Also looking to connect my balance leed right to my - and + wires right off the charger, can they still balance right if they are not ran right to the battery.

Yes, there are companies out there who make balance lead extensions.

will it still balance right if the balance leeds are ran through the - and + wires?

It will throw it off a little, as the balance voltage reading will be off by the amount of voltage drop through the main cables. Should slow the charge down slightly. If it's a 2S lipo I wouldn't expect balancing issues, but on larger cell counts it would throw cell to cell off a little during the charger, should be closer after finishing the lower amp CV portion though. Assuming the middle balance wire(s) are connected of course.

Probably not the end of the world, but not ideal practice.
