On the other hand, if you under-pressure an input, not much harm can be done, it just won’t power up. Over pressurizing a power input continuously can damage the device, so this is something to take serious when selecting a battery solution. If you followed along, you can see that’s a tad bit too high for the Zoom F8, which gives a maximum input of 16. the (Lithium Ion) IDX battery in the example above will give a 16.8v rating when charged for example. One reason is that certain battery chemistries are fluctuating when the battery is charged or discharged. There are a couple of reasons input is given in a range instead of an absolute number. A Sound Devices 633 states that the external input accepts everything from 10 to 18 Volts. Now lets focus on what we need for a recorder. So or we get a battery with a voltage in the spec range of the equipment, or we take a battery and step up/down the voltage in various ways to get it in range (more on the latter in the next chapter about BDS). We can’t just give a piece of gear 1.2V, when it’s expecting 12v. BUT: remember I wrote: Arguably the most important spec for our equipment is the voltage. Now in theory, the device I used as an example for the AA, would last for 68 hours with the NP1. The IDX NP1 Battery shows everything, 14.8V * 4.6A = 68 Wh. With this info we can calculate run time for example, lets say we use this battery for a device that is using 1 watt per hour, thus we know 1 battery will run for about 3 hours. No wattage is given on the package, but Watt’s law thought us V(oltage) * A(mperage) = W(attage), thus 1.2 * 2.5 = 3 Watt (Hours). Let’s take a look at a simple rechargeable AA battery packaging sleeve and the print on a NP1-style battery:Īs I circled out, the AA Battery has a voltage of 1.2 and an amperage per hour rating of 2.5 (2500 milli amp hours). Arguably the most important spec for our equipment is the voltage. I don’t want to bore you to sleep with a lecture on what a battery is, but a tiny bit of technical background info is always good to carry with you.Įvery battery has a positive and negative connection (the positive is the cathode, the negative is the anode), a given (charged) voltage (electric pressure) a rated current (amperage or amps per hour) and the potential power output (wattage, or wattage per hour). Battery distribution system (BDS) and mountsīatteries: A Battery is a battery, is a batteryĪn electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars.Batteries: A Battery is a battery, is a battery.This is part one of a series of articles, split up as follows: Therefore, this guide, including recommendations for the various bits and pieces. the crux of most of the questions boils down to not completely understanding the basic essence of what’s needed to get your gear running throughout the day. Followed by loads of reactions, based on personal preferences, what the person is used to, or what the ‘hot new kid on the block’ is at the moment.īut what is often neglected is the pure technical background of DC power. It’s a question popping up about every week on the various groups and forums online: ‘How do I power my field recorder?’ or, ‘ What are the best 12v+ batteries out there?’.
