Renogy Pro 12V 500Ah Underseat Smart Lithium Battery

Short Product Summary

The Renogy Pro 12V 500Ah Smart Lithium Battery is the largest single battery in the Renogy Pro range: roughly 6.4 kWh of LiFePO4 capacity in one unit, with built-in Bluetooth, self-heating for cold-weather charging and a 60-feature BMS with active cell balancing. This is the battery for people who want to stop thinking about power altogether.

Why This Product

Most off-grid frustration comes down to capacity. Run a compressor fridge, lights, water pump, laptops and an inverter for a kettle, and a 100 Ah bank starts to feel small by the second cloudy day. At 500 Ah in a single case you get genuine multi-day autonomy without stringing four batteries together, which also means one BMS, one set of connections and far fewer things to go wrong. For long stays in the Kgalagadi or extended Cederberg trips, that changes how you travel.

Key Features

• 500 Ah capacity, approximately 6.4 kWh – true multi-day autonomy from a single battery.
• One battery instead of a bank – a single BMS and one set of terminals rather than four batteries wired in parallel.
• Over 4,000 cycles – at 80% depth of discharge, a genuinely long service life.
• Built-in self-heating – charges safely in freezing conditions, operating down to -20 °C.
• Integrated Bluetooth – live state of charge, current and health through the Renogy app.
• Advanced BMS with active cell balancing – 60 built-in safety features including over-charge, over-discharge, short circuit and thermal protection.
• Supports large inverters – the capacity and discharge capability to run a 3,000 W inverter properly.
• LiFePO4 chemistry – the safest, most stable lithium chemistry for leisure and off-grid use.

Ideal For

• Large off-road caravans and expedition motorhomes living off-grid for days at a time.
• Systems running a 2,000 W to 3,000 W inverter with real domestic appliances.
• Overlanders and remote-area travellers who need serious autonomy between charges.
• Mobile offices, film and survey vehicles with heavy daily power demands.
• Anyone replacing a tangle of parallel batteries with one clean installation.

Local Support from 4Matt Campers

4Matt Campers is a Renogy dealer in Cape Town, serving the Western Cape and delivering across South Africa. A 500 Ah battery is a serious purchase and the installation deserves proper planning: mounting and weight distribution, cable and fuse sizing, and enough solar and DC-DC charging to actually refill it. Come and talk it through with us in the showroom before you commit.

• 1 × user manual

Optional Fitment & Upgrade Notes

• This is a heavy unit. Plan the mounting position carefully for both weight distribution and secure restraint, particularly on an off-road trailer.
• Size your charging to the bank. A 500 Ah battery needs meaningful solar plus a DC-DC charger, or it will never reach full charge on tour.
• Use appropriately heavy cable and fusing, especially if feeding a 3,000 W inverter.
• Confirm the physical dimensions against your intended location before ordering; we can supply exact figures.
• A shunt-based monitor is worth adding alongside the Bluetooth readout on a bank this size.

Complete Your Setup

• Inverters & Inverter Chargers – 2 kW and 3 kW units that this bank can genuinely support.
• Solar Charge Controllers – 60 A MPPT regulators to refill it.
• Solar Panels – enough array to keep 500 Ah topped up.
• 12V Electrical Accessories – heavy cable, fusing, shunts and monitors.
• Renogy Range – the full Renogy line-up at 4Matt Campers.

FAQ

Is 500 Ah overkill?
Not if you run an inverter for cooking appliances, a compressor fridge and several devices while staying put for days. If you mostly tour between powered sites, a 100 Ah to 200 Ah battery is usually plenty. We will give you an honest answer either way.

How much solar do I need to recharge it?
Considerably more than a single panel. Talk to us with your typical daily consumption and we will size the array and controller properly.

Can it run a 3,000 W inverter?
Yes, this is the sort of capacity a 3 kW inverter needs behind it, both for runtime and discharge capability.

What does self-heating do?
Lithium must not be charged below freezing. The integrated heater warms the cells first so charging is safe down to -20 °C.

Is one 500 Ah better than four 100 Ah batteries?
Generally yes. One battery means one BMS, one set of connections and no risk of imbalance between parallel units.
