You can go to an auto parts store and get a made up cable to do this.
Typical cable will be #4, a 4 foot piece of #4 at 25 Amps will have a voltage drop of 0.05 volts. Unless you are planning to try to charge at some unusual rates, or run a BIG inverter, this will be more than adequate.
You don't talk about the rest of your wiring. If you are planning to tie this to a distribution panel located elsewhere, all the wiring lengths and draws need to be figured in. The size and drop of the jumper is no more or less important than the size and drop of the total wiring between panel and batteries and between the batteries themselves.
