Renogy 12V 300Ah Core Mini Lithium Battery

Short Product Summary

The Renogy 12V 300Ah Core Mini Lithium Battery is a high-capacity LiFePO₄ deep-cycle battery that packs 3840Wh of usable energy into a compact, drop-in 12V case. With built-in low-temperature charge protection and a long cycle life, it's built for serious off-grid, caravan and backup-power systems that need to run for days.

Why This Product

For bigger setups — a caravan fridge, lights, an inverter and devices running off-grid for days — you need real capacity. The 300Ah Core Mini delivers it in one compact lithium battery, with the safety of low-temperature protection so it won't charge in damaging cold, and the long cycle life that makes lithium far better value than lead-acid over time.

Key Features

• 3840Wh of usable energy – 12.8V nominal, 300Ah capacity for extended off-grid running.
• LiFePO₄ chemistry – safe, stable lithium iron phosphate with a long service life.
• Low-temperature charge protection – prevents charging in damaging cold to protect the cells.
• Long cycle life – up to ~5000 cycles at 80% depth of discharge, far outlasting lead-acid.
• Built-in BMS – protects against over-charge, over-discharge, over-current and short circuits.
• Compact drop-in 12V design – big capacity in a manageable footprint.

Ideal For

• Large caravan, trailer & camper builds needing days of off-grid power
• Overlanders running a fridge, inverter and lights for extended trips
• Home & off-grid backup where high capacity and long life matter

FAQ

How much can a 300Ah battery run?
With 3840Wh it can run a 12V fridge, lights and an inverter for days, depending on your loads. We'll help you work out realistic runtime for your setup.

What is low-temperature protection?
The battery prevents charging when it's too cold, protecting the lithium cells from damage — useful for winter use.

Can I connect more than one?
Yes — Renogy lithium batteries can be expanded for more capacity. Ask our team to confirm the correct configuration.
