![]() As the name suggests this means how many amps the battery can deliver in an hour. Capacity – Amp hours (Ah):īattery capacity is measured in Ah, or Amp-hours. The power consumption of the trolling motor is now 300W. When I switch to gear / speed setting 4, the engine draws 25A and still runs on 12V. The engine runs on 12V and draws 15A and thus has a power consumption of 180W (12 x 15). So the power consumption is 24 x 30 = 720W.Įxample 3: Suppose I have another Minn Kota Endura C2 50 LBS that I am running in gear / speed setting 2. This goes up when the number of amps also goes up.Įxample 2: Suppose I have a 24V Minn Kota Terrova 80 LBS bow motor that draws 30 amps. This is the amount of energy consumed by a device and therefore an indication of how powerful it is. Power is the voltage multiplied by the number of amps, or W = V x A. The voltage has remained the same but the number of amps has gone up. The engine still runs on 12V but now pulls 25A. I decide to go a little faster and I switch to gear / speed setting 4. The trolling engine runs on 12V and currently draws 15A. An electrical device usually works on a fixed voltage, but the amount of amps it draws can vary depending on, for example, the position of your trolling engine (a trolling engine at full throttle draws more amps than in half throttle for instance).Įxample 1: Suppose I have a Minn Kota Endura C2 50 LBS that I am running on gear / speed setting 2. If the number of amps goes up, then current flowing through the device per second also goes up. When we talk about amperes (or amps), we are talking about how much electricity “flows” per second. For example, a device that works on 12 volts obviously needs a battery that also supplies 12V. 12, 24, or 36 volts) and a device always works at a certain voltage. A battery always has a fixed voltage (e.g. With a 12V device, 12 volts are always “given” from the battery. ![]() By a circuit we mean, for example, an electronic device. The number of volts is the amount of energy given to an electronic circuit. ![]() Below we will try to explain what it all means. We understand that all this terminology can be a bit confusing at times but once you know how it works it is quite simple. ![]()
