Colorado Drone Chargers Freefly SL8 Portable Rapid Charging System
Ships in 1-2 weeks
The Colorado Drone Chargers SL8 PRCS (Portable Rapid Charging System) is a four-bay field charging case for Freefly SL8 batteries. It charges four SL8 packs and two USB accessories at the same time, averaging about 65 minutes per cycle, so a single case can keep an Astro in the air through long survey, inspection, and emergency response days. The charger lives inside an impact-resistant, watertight, dust-proof hard case with a pressure release valve, ready to roll straight from the truck to the flight line.
Four SL8 batteries plus two USB devices, charged in roughly 65 minutes, off any pure or modified sine wave inverter or generator.
Features
- Charges four Freefly SL8 batteries and two USB accessories simultaneously
- Average full charge time of about 65 minutes per battery
- Runs from grid power, pure sine wave, and modified sine wave inverters and generators for true field deployment
- 100% duty cycle: run cycle after cycle without forced cooldowns
- Multi-fan cooling with voltage and temperature management for safe rapid charging
- Impact-resistant, watertight, and dust-proof hard case with easy-open pressure release valve
- Auto-switching universal input (88 to 264 VAC, 47 to 63 Hz) for use in the US and abroad
- Backed by Colorado Drone Chargers' lifetime warranty

FAQ
How much faster is this than charging one battery at a time?
The PRCS charges four SL8 packs in parallel at an average of about 65 minutes per battery. A single bay charger handles one battery in a similar window, so the PRCS effectively quadruples your throughput per cycle. For Astro operators who fly two packs at a time, that is two full flights ready to go after each charge cycle.
Can I run it off a generator or inverter in the field?
Yes. The PRCS accepts both pure sine wave and modified sine wave power sources, so it works with a wide range of portable generators and inverters. Colorado Drone Chargers publishes inverter and generator sizing guidance: at 750 W max, plan on an inverter or generator rated comfortably above that to allow for inrush and headroom.
Will it work outside the United States?
Yes. The input is auto-switching from 88 to 264 VAC, 47 to 63 Hz, so the same unit runs on US, EU, UK, and most other grid standards with the appropriate AC cord.
What is the 100% duty cycle rating?
It means the charger is designed to run continuously, cycle after cycle, without a required cooldown between sessions. Combined with the multi-fan cooling and temperature management, that is what makes it suitable for long mapping or inspection days.
Does it talk to the SL8's smart electronics?
Yes. The PRCS is built specifically for the Freefly SL8 platform and delivers 25.4 VDC tailored to the pack's charging profile. The SL8's built-in Battery Management System still handles cell-level protection and reporting on the pack's OLED screen during charging.
Can I check on charge status while it is running?
Each SL8 pack has its own OLED status screen that reports state of charge, voltage, current, and temperature, so you can read progress directly from the battery while it is in the bay.
What is the warranty?
The PRCS is backed by Colorado Drone Chargers' lifetime warranty. Reach out to us if you have any questions about claims or service.
