Renogy 12V 100Ah PRO Smart Lithium Battery

Short Product Summary

The Renogy 12V 100Ah PRO Smart Lithium Battery is a premium LiFePO₄ (lithium iron phosphate) deep-cycle battery built for serious off-grid, caravan, marine and backup power. It combines Bluetooth 5.0 app monitoring, an automatic self-heating function for cold conditions, and an automotive-grade BMS in a rugged IP65 case — a true drop-in 12V replacement with 1280Wh of usable energy and a 5000-cycle design life.

Why This Product

If you're tired of heavy lead-acid batteries that drain half their capacity, die in a few seasons, and leave you guessing about state-of-charge, the 100Ah PRO is the upgrade that fixes all three. You get far more usable power in a lighter package, real-time monitoring on your phone, and the confidence of cold-weather self-heating for early-morning winter charging — so you can load up, head out, and stop worrying about your power.

Key Features

• 1280Wh of usable lithium energy – 12.8V nominal, 100Ah capacity for fridges, lights, inverters and more.
• 100A continuous discharge – with 200A peak (10s) and up to 245A for 30s to handle heavy startup loads.
• Automatic self-heating – activates below 5 °C so the battery charges safely in the cold, then switches off above 10 °C.
• Bluetooth 5.0 + Renogy app – live voltage, current, temperature and state-of-charge, with over-the-air firmware updates (RenogyONE compatible).
• Automotive-grade BMS – 60+ protection mechanisms with active backup protection that cuts the circuit ~40× faster than passive systems.
• 5000-cycle design life – at 80% depth of discharge, up to ~5× the life of typical lead-acid.
• Rugged & safe – IP65 dust- and water-resistant ABS case, 99% efficiency, <3% monthly self-discharge.
• Drop-in 12V replacement – M8 threaded terminals for a simple, secure swap.

Ideal For

• Caravan, trailer & camper builds needing dependable 12V house power
• Overlanders and 4x4 touring setups running fridges, lights and inverters off-grid
• Clients wanting app monitoring of their battery from their phone
• Cold-climate and winter travellers who need safe charging in low temperatures
• Home and marine backup where long cycle life and safety matter

FAQ

Is the Renogy 100Ah PRO a drop-in lead-acid replacement?
Yes — it's a 12V LiFePO₄ battery with M8 terminals designed to replace a 12V lead-acid/AGM battery, with far more usable capacity and cycle life. Just make sure your charger supports a lithium profile.

What does the self-heating do?
When the battery drops below 5 °C and charging is applied, it automatically warms itself so it can charge safely, then switches off above 10 °C — ideal for cold winter mornings.

Can I monitor it on my phone?
Yes — Bluetooth 5.0 connects to the free Renogy app for live voltage, current, temperature and state-of-charge, and it's compatible with the RenogyONE display.

Can I connect more than one?
Renogy lithium batteries can be expanded for more capacity. Ask our team to confirm the correct series/parallel configuration for your setup.
