Here's what you do to run either way…
(2) 2S for 6 lap sprint races (5000mAh min recommended, accomplished w/ (2) 2S 5000mAh in series)
(2) 4S for 4 minute offshore races. (8000mAh min recommended, accomplished w/ (2) 4S 4000mAh in parallel)
Here’s what I do… you can use your choice of connectors to accomplish this.
As I said earlier, cut off your existing series setup with deans connectors.
Put male 6.5mm bullets on the esc positive and negative. Then make yourself both parallel and series harnesses to connect to those bullets. I use green Castle 6.5mm plugs for all my batteries. I even have a harness for a single 4S battery if I want to use that way.

Also… most guys simply use 5.5mm bullets at the end of the esc leads and same on batteries. Most prefer this method because it eliminates that extra set of connectors I have between my different harnesses and the esc. More connections have more potential for more resistance.
- To hookup (2) 2S in series: connect one 2S battery’s negative to the esc negative and then the other 2S battery’s positive to the esc positive. Then you have a separate wire with 5.5 bullets to connect the remaining positive and negatives on the batteries together.
- To hook up (2) 4S in parallel: use a parallel adapter set like shown in photo which allows you to connect the positive and negative of both batteries straight to the esc leads.

The typical is to put a male bullet on the battery negative and a female bullet on the battery positive. And thus put a female bullet on the esc negative and a male on the esc positive.
