Frequently Asked Questions
How do I size a battery for my outdoor PA?
Add up continuous wattage for all devices and multiply by hours of use to get watt-hours (Wh). Choose a battery with at least 20-30% extra capacity and avoid discharging Li-ion below recommended depths. For frequent events, consider LiFePO4 packs for longer cycle life.
Can I run cameras and speakers from the same battery bank?
Technically yes, but separate banks or distribution circuits are safer. Isolate audio power from monitoring gear to prevent a camera or phone charger from affecting speaker headroom. Use fuses and dedicated outputs for critical gear.
How do I prevent startup surges from overloading my battery/inverter?
Choose an inverter with a peak surge rating above combined speaker amplifier startup draws, stagger turn-on times, and use soft-start features where available. If a speaker has a large amplifier, dedicate a separate inverter or bank to it.
