Renogy 12V 300Ah Core Series Lithium Battery with Self Heating

Renogy 12V 300Ah Core Series Lithium Battery with Self-Heating

Meet the Renogy 12V 300Ah Core Series LiFePO₄ Battery — a reliable, future-proof solution designed to make upgrading from lead-acid to lithium simpler, faster, and more rewarding. Built inside a rugged, road-ready housing and fully compatible with Renogy solar panels, charge controllers, and inverters, this battery removes guesswork and delivers dependable power wherever your journey takes you.

More power, more possibilities

The 300Ah capacity delivers 59% more usable energy than a 200Ah battery of the same size, giving you the extra runtime needed to stay powered during storms, outages, and extended off-grid adventures. Built with EV-grade lithium cells, it provides nearly 10× the lifespan of traditional lead-acid batteries, reducing replacements and long-term costs.

Industry-leading self-heating for cold climates

Cold weather no longer limits your power. Featuring 200W self-heating elements, the battery activates automatically at 32℉ (0℃) and heats 2× faster than standard heated batteries. This ensures stable charging and reliable output even in harsh winter conditions (requires >10A charge current per battery to activate heating).

Built-in protection for real-world use

Off-grid systems face vibration, temperature extremes, and heavy loads. That’s why the Core Series includes:

• A true 200A Battery Management System (BMS)
• Low-temperature charging cut-off for safety
• IP65-rated protection against dust and water
• Shock-resistant internal structure to protect components on rough roads and waters

This is power you can trust — on land, at sea, or off the grid.
