Gear Guide: Batteries and Power Solutions for Marathon Streams and Concerts

Power is the unsung hero of any long-duration event. When a camera, mixer, or lighting rig dies mid-set, it derails the entire viewer experience. This guide covers dependable battery systems, UPS strategies, and practical tips to keep your gear running through multi-hour streams and concerts.

Primary power strategies

Three common approaches dominate live production:

1. AC power with UPS backup: Best for fixed venues, racks, and critical streaming servers. Use a UPS with enough runtime to ride through short outages and provide graceful shutdowns.
2. V-mount or Gold mount battery systems: Ideal for camera operators and mobile setups. Large-capacity V-mount packs (98Wh+ per battery) can run a camera for hours with the right consumption assumptions.
3. Hybrid systems: Combine AC feeds with battery hot-swapping or UPS that can be bypassed to avoid interruptions during extended runtime.

UPS selection tips

Choose a UPS based on load planning, not guesswork. Sum the wattage of critical devices (encoders, routers, switchers) and add headroom. For multi-hour events, UPS systems aren't designed to run everything for hours; they buy you time to switch to generator power or perform a controlled shutdown.

Generator considerations

A portable inverter generator is a practical backup for outdoor events. Ensure low THD (<5%) to protect sensitive electronics. Synchronize loads to avoid large inrush currents; stagger powering on of dimmers and lighting rigs.

Battery hot-swap workflows

For cameras and mobile devices, hot-swapping batteries reduces downtime. Implement redundancy: two batteries on a single output circuit with a bridge that allows swapping without cutting power. Keep spares charged and labeled for rotation.

Power distribution and cable management

Use labeled, color-coded runs and secure cables away from foot traffic. Distribute load across phases when possible and avoid daisy-chaining power strips. Keep critical feeds on dedicated breakers to minimize risk from unrelated faults.

Monitoring and logging

Real-time power monitoring is invaluable. Many modern UPS and power distribution units offer SNMP or cloud reporting; log voltage and runtime to forecast failures. Train crew to react to alarms, and script handoffs to secondary power sources well before thresholds are reached.

Recommendations

• Fixed broadcast rigs: 2–3 kVA UPS + generator plan.
• Mobile camera setups: Two V-mount batteries with one hot-swap ready; at least one spare per camera.
• Small venues: UPS for streaming encoder and network; local outlets for stage power but with monitored distribution.

Common pitfalls

• Mismatched battery chemistries in the same rig.
• Failing to account for inrush current from lighting systems.
• Not testing full-load runtime under real conditions.

Final words

Power planning is preventive work that rewards attention to detail. Integrate power checks into load-in checklists, run full-dress rehearsals under production load, and maintain spare capacity for critical systems. When duration matters, reliable power is non-negotiable.
