wire for esc and battery

[RC944]

is this the correct gauge for the esc to battery? anyone know whether 2.30 is the going rate per metre? found it on ebay for that much but wondering if shorter runs available?

what is the best place to buy leads that run from lipo backs with the banana plug style connectors into female deans? can these be made using the 14 gauge or should it be lower gauge?

cheers and thanks
