Tired of having your batteries die in the field–or, just as annoying–taking too many to find that you hiked with that extra weight the whole time? Some of us have our kits and consistent gear down to an imperfect science, where we eye the project and our available resources and make judgement calls based on years of experience with the batteries we use and how we use them. Realistically, for many, this is not yet the case, so I wanted to implement an early-stage tool for those out there finding themselves pulling their hair out with one hand and calculating their battery lives for field use (before they hit the ground running) with the other.
Use this chart to look at the amount of power you’re going to draw based on peripherals. Go from milliamps to amps to watts and back as necessary. Share this, as it’s a useful tool in your arsenal when planning long days and traveling shoots.
Next time something like this comes up I’ll have the embed in wordpress down to a science and post formulas through excel properly (or we’ll get it to work on our main site as a resource).
