The Owner's Insights on the 300Ah Lithium Power Kit
Blokes ring us wanting one thing: power that just works. No second job. This kit's built for exactly that. Its Core Mini battery is 300Ah, 3,840Wh, in a case still small enough for your caravan locker or camper trailer bay.
The battery alone is about 25kg, a touch more than a bag of cement, so plan your mounting properly. Don't just screw it to a shelf and hope. The 2000W inverter runs your fridge, your kettle and your laptop charger without blinking. The 50A DC-DC charger tops your bank up off the alternator on the drive in, or off solar once you're parked.
Worth knowing before you buy: the inverter's own cover is 1 year, well short of the battery's 5. Hard on gear? Budget for that. And get a licensed sparky to fit the RCD the inverter doesn't include.
What Customers Say About the 300Ah Lithium Power Kit
Owners who've run the Core Mini 300Ah a season or two call it a genuinely brilliant option for its size and weight. Most say it's kept them off-grid far longer than they expected before it needed a proper recharge.
The recurring theme: it's more battery than most weekend campers need. Chasing real time off-grid, that headroom is exactly the point.
Why You'll Love the 300Ah Lithium Power Kit
- Core Mini 300Ah LiFePO4 battery 3,840Wh packed into a case only 384 x 253 x 194mm, so it fits a locker most 300Ah batteries won't.
- 2000W pure sine wave inverter with UPS transfer switch Runs your fridge, your kettle and your sensitive electronics clean, switching to mains in under 50ms on a powered site.
- 50A DC-DC charger with MPPT Charges off your alternator on the move or off solar at camp, up to 97% charging efficiency.
- 500A battery monitor with shunt See your voltage, current and state of charge on a backlit screen instead of guessing.
- Rated for 5,000+ charge cycles Run it hard every single weekend and it'll still outlast the vehicle towing it.
- Optional ×3 200W ShadowFlux solar Add the panels on your With Solar kit and keep your bank topped up without starting the engine.

No Solar or With Solar: which 300Ah kit to pick
Mostly weekend trips, charging off your alternator on the drive in? The No Solar kit covers you. Parked up for days at a time and want your bank topping up without the engine running, add the ×3 200W ShadowFlux panels. They're also the better pick if you often camp somewhere your vehicle can't reach direct sun. The anti-shading tech keeps output steadier under trees than a standard panel.
Installing the 300Ah kit in a caravan or camper trailer
This is a kit you wire in, not a plug-and-play unit. Your battery needs a secure tray or bracket, not included. Your inverter's AC side needs an external RCD rated 30mA or under, to meet AS/NZS 3000 wiring rules. It doesn't have one built in. If that's outside your comfort zone, get a licensed auto-electrician to run the install. It's a straightforward job for one tradesperson, done right the first time.
How much power 300Ah gives your caravan
At 3,840Wh, this bank runs your 60L camp fridge for around 76 hours. That's more than three full days before it's flat. And that's before you've drawn anything else. Your fridge and a 1,500W kettle together still sit under your inverter's 2000W rating. Run a fridge, lighting, a water pump and charging gear, and 300Ah is genuinely more than enough headroom for you.

Not Sure Which 300Ah Lithium Power Kit Suits You?
Only running a fridge, lights and charging your phone on weekends? This kit is plenty. The No Solar option saves you the panel cost too. Off-grid for a week or more, or running a full-size kettle and an air compressor together, look at the 400Ah Lithium Power Kit instead. One thing worth flagging: this is a kit you wire in, not a plug-and-play power station. If you'd rather skip the install, a portable power station suits you better. Every component here carries Renogy's own manufacturer warranty. We'll back you up sorting a claim if you ever need one.
