Connecting two RC batteries in collection is a not unusual apply to extend the voltage output. That is accomplished by means of connecting the certain terminal of 1 battery to the unfavorable terminal of the opposite battery, after which connecting the remainder certain and unfavorable terminals to the circuit. The voltage output of the 2 batteries might be additive, that means that two 3.7v batteries hooked up in collection will produce a voltage output of seven.4v.
There are a number of advantages to connecting RC batteries in collection. First, it might building up the voltage output of the batteries, which will also be essential for powering high-power units. 2nd, it might lengthen the runtime of the batteries, as the overall capability of the batteries might be larger. 3rd, it might assist to stability the burden at the batteries, as the present draw might be flippantly allotted between the 2 batteries.
