Palmer BC400 Aa V1

A Rack Solution Designed for Professional Setups

The Palmer BC 400 AA V1 is aimed at musicians, technicians, and service providers who want to centralize and secure battery management in a demanding environment. Its 19-inch rack format allows for a clean integration into a flight case or rack, keeping your device power supply under control just like the rest of your system.

Designed for intensive use, it provides a simple solution to a recurring problem: avoiding interruptions caused by insufficiently charged, scattered, or hard-to-track batteries when multiple devices are running simultaneously.

Who and What For: Stage, Rehearsals, Studio, Performance

This charger is ideal if you regularly use wireless microphones, in-ear monitor systems, effect pedals, or any other battery-powered equipment. At concerts, it minimizes last-minute changes and helps standardize your routines (charging, rotation, monitoring). In the studio or rehearsal room, it allows you to keep a set of batteries operational at all times without multiplying household chargers.

Thanks to its 4 separate charging stations, you can organize your batteries by usage (for example: one group for transmitters, another for receivers, one for accessories), while maintaining the flexibility to charge AA and AAA batteries as needed.

Key Features: Smart Control and Safe Charging

Battery-by-Battery Monitoring

The Palmer BC 400 AA V1 is microcontroller-controlled and monitors the charge level of each individual battery. This separate management is especially useful when batteries do not all have the same usage history: it helps maintain consistent charge and more easily identify a battery that becomes unstable over time.

Defective Battery Detection and Built-in Protections

To secure your battery stock, the charger can detect defective batteries and includes protections against overcharging and short circuits. These functions are essential in a professional context, where charging cycles are frequent and where preserving the lifespan of rechargeable batteries while reducing the risk of incidents is a priority.

Expandable with 9-Volt Charging Drawers (Optional)

If your rig includes 9-volt powered devices, dedicated charging drawers are available as an option. Each drawer can hold two 9-volt blocks, and they can be combined with the AA/AAA drawers according to the desired configuration. This way, you adapt your charging station to your equipment stock without changing your rack installation logic.
