Back in the olden days, thermostats were simple on/off devices that didn''t need their own continuous power supply. Modern thermostats with Wi-Fi and backlit display, by contrast, need a steady supply of juice. The C wire, or "common wire" enables the continuous flow of 24 VAC power to the thermo
Rechargeable batteries can cost more than twice as much as single-use batteries, but if you use them properly they''ll save you money in the long run because you can recharge them hundreds of times.
Motors handle about one quarter of the current from the battery. The recommended motor FPV wire size is 20awg to 18awg. Some pilots run the thinnest motor wire they can to minimise weight. The resistance of thin high-power wire will force the battery to supply high current which can result in voltage sagging.

When you wire 4 batteries together in series-parallel, you wire 2 batteries together in series (+ to –), creating a set. You then wire the other 2 batteries together in series (+ to –), creating a second set. Finally, you wire the two series sets of batteries to each other in parallel. (See a video demonstrating this on )
What gauge wire is a car battery cable? This question would vary depending on the specific model of the car. Typically, a 12-volt battery cable at most is 18 AWG wire. If you know the amperage of your battery charger, you can calculate the wire size based on that information. Battery cables infrequently break on cars and trucks, but they do ...
In the AWG system, the higher the number of the cable rating, the thinner the wire and, therefore, the less current it can carry. For example, if you look at the chart below, you will see that 12 AWG, which has a diameter of 2.05 mm, can carry 20-25 …
