Top Reasons to Upgrade to Renogy Heated Batteries

DuoHeat Tech

Auto-Heating

Power Efficient

Longer Lifespan

Faster Access to Power

Featuring 110W of dual-heating power for double the efficiency, DuoHeat Tech allows Core Mini 12V 100Ah to warm up 40% faster and reach a ready-to-charge state from -22°F (-30°C) in just 60 minutes. Your adventure doesn't stop for winter.

Warmth at the Right Time

Renogy's self-heating batteries can heat up in advance to prevent cells from freezing and trigger low-temperature charging protection. And the heating only turns off once the cell temperature is well above freezing for stable operation.

Heating Without the Drain

Unlike batteries that drain themselves to heat up, Renogy's heated LFP batteries use power from your charger. This means all your battery's power is saved for your off-grid life, guaranteeing full runtime and optimal performance even in cold conditions.

Power for a Decade

Don't let cold weather kill your batteries. Renogy's self-heating LiFePO4 batteries last far longer—10x longer than lead-acid and 1.6x longer than standard lithium—saving you from constant replacements and offering decade-long power in winter months.
