How We Plan Power and Batteries on a Remote Shoot

Power planning quietly decides what we can shoot on a remote day. It gets settled the night before, at the equipment table — not improvised on location when a recorder's low-battery light comes on during the one take a subject was willing to give. A dead battery on a single-take interview, or on a field recording that can't be repeated, isn't a retake. It's a lost day, and a remote call sheet usually doesn't offer a next one.

We've learned to treat the battery count the same way we treat the shot list: decided in advance, checked twice, never assumed to be flexible once the crew is on the road.

What We Actually Carry Into the Field

Capacity beats cleverness. Field recordists who work well beyond mains power for a living don't chase the biggest single battery — they carry a stack of compact, high-capacity cells that add up to more runtime than the day needs. Chris Watson carries batteries the size of a packet of cards that, six at a time, add up to roughly a week's power in hand luggage, with his recorder running eight or nine hours per cell. That's the model we borrow for our own field kit: several small, reliable units instead of one large one that becomes a single point of failure the moment it dies, or gets left charging in a hotel room.

The gear itself has changed the math too. On-set battery systems now span a wide range, from airline-friendly compact packs to high-capacity floor batteries built for long, uninterrupted sessions. We size our own kit closer to the compact end — the same instinct behind how we handle data on a small crew, favoring gear that fits in a backpack over gear that needs its own case. It's also part of why we don't use lavalier mics for our own shoots: fewer wireless bodies, fewer battery types to track, fewer things that can go quiet on us at once.

Solar has a place in that kit. Just not the place people assume. It keeps a phone topped up — that's about it. It has never carried the load for a camera body or a field recorder across a full shooting day, especially with limited direct sun, and we've treated that as a given rather than something worth re-testing every season.

What We Changed After Running Out Once

The days that matter most on a remote schedule — one location, one chance, no recharge before the light goes — get planned around a fixed, finite battery count decided before the crew leaves. It's the same discipline documentary crews use on extreme-condition shoots, where a recharge simply isn't coming. We budget more cells than the math says we need. Not because the math is wrong, but because conditions on location rarely match the spreadsheet: cold cuts runtime, a longer setup eats into the margin, and weather changes the plan without warning, the way a wet call sheet changes everything else about a day.

What we didn't chase was the smart-monitoring end of the market — batteries that report their own health over an app, systems built for a fleet of units on a much bigger production. For a small crew, redundancy in cheap, simple cells beats one expensive system with a single point of failure. If a battery dies, we swap it and keep rolling. We don't want to be troubleshooting a platform on the one day we can't afford to lose an hour.

The batteries are the plan now, not an afterthought to it — counted before the crew leaves, not after someone runs out. It's the same instinct that shapes how we listen on location: sound work on a remote day depends on power holding as much as it depends on anything else in the kit.
