Feigao/MM wiring connectors

I am trying to wire the MM controller to the feigao 8xl. What size bullet connectors come on the MM, it doesnt say in the manual but they look like 4mm? What do ya'll suggest i use as connectors between the motor and MM, bullet (what size) or deans, for the other batter connections as well? I am wiring two 2s2p packs in series to get 14.8 volts, so I will have a total of three connections between the two batteries and the ESC. I am putting this on a LSP. Thanks.
