Its up to you...

You could change over to deans or traxxas style plugs.

But there are plenty of batteries out there that come with banana 4.0 plugs. I have a 2s 5000mah lipo with banana plugs that i use for my volcano epx pro.

And while the banana plugs are a bit bulky, they keep water out (unlike deans) and dont have alot of resistance (like tamiya plugs, which many redcat models used to have)
