Parallel connectors join (2) batteries together and double the mah, while the voltage remains the same. An example would be (2) 2100mah 3S 11.1V batteries joined in parallel, which would equal (1) 4200mah 3S 11.1V battery.
Note: Be sure to only use (2) batteries of the same mah, voltage and C rating. Using mis-matched batteries can damage the batteries, and/or the electronics in use. Also, be sure both batteries are fully charged and balanced before use; if one battery has a lesser charge, it may be drained below a safe capacity, thus damaging the cells.
