In this video, we upgrade the battery system in our Amateur Radio Emergency Services (ARES) trailer from a 100Ah battery to a powerful 320Ah LiFePO4 lithium battery — the Redodo 12V 320Ah Mini Bluetooth Lithium Battery.
This major power upgrade dramatically increases our emergency communications runtime, improves efficiency, and reduces weight compared to traditional AGM or lead-acid batteries. If you're building or upgrading an ARES trailer, ham radio go-kit, EMCOMM setup, or off-grid power system, this video breaks down everything you need to know.
🔋 Why Upgrade to 320Ah LiFePO4?
• 3X the usable capacity compared to our old 100Ah battery
• Higher continuous discharge current for radios, repeaters, and field equipment
• Faster charge rates for generator or solar charging
• Built-in Bluetooth monitoring
• Low-temperature charge protection (critical for emergency deployments)
• Longer cycle life vs AGM or flooded lead-acid
⚡ Specs We Discuss:
• Continuous discharge current & peak discharge ratings
• Recommended charge current
• Built-in BMS (Battery Management System) protection
• Low-temp charging cutoff
• Weight comparison vs lead acid
• Real-world runtime improvements for ham radio operations
This upgrade makes our ARES trailer more resilient for:
• Emergency communications deployments
• Field Day operations
• Disaster response
• Off-grid portable radio setups
• Solar-powered ham radio systems
If you're into ham radio, ARES, emergency preparedness, off-grid battery systems, solar generators, LiFePO4 upgrades, or mobile command trailers, this deep dive will help you decide if a 320Ah lithium battery is right for your setup.
