12V 300Ah Lithium LiFePO4 Battery, 200A BMS 3840Wh Rechargeable Lithium Iron Phosphate Battery for Solar Energy Storage, Backup Power, RV, Camping, Off-Grid, Marine

High-Capacity & Space-Saving Design: This 12V 300Ah lifepo4 battery / lithium iron phosphate battery provides a stable 3840Wh large energy output with a compact structure for easy installation and transport. As a deep cycle battery with high energy density, it performs more efficiently than traditional lead-acid batteries, making it perfect for large-capacity energy storage and space-limited installations.

• Reliable Deep Cycle Performance: Built with high-quality lithium iron phosphate cells, this 12V 300Ah deep cycle battery maintains stable performance under frequent charge and discharge cycles. With a rated discharge depth of ≥80%, it provides a much longer service life compared to standard lead-acid batteries (200-500 cycles), bringing better cost efficiency for long-term energy storage use.
• Built-in 200A BMS for Full Safety Protection: This 12V 300Ah lithium iron phosphate battery comes with an integrated 200A Battery Management System (BMS) that offers complete protection against overcharge, over-discharge, overcurrent, short circuit and abnormal temperatures. The automatic high/low temperature cut-off function ensures safe charging and discharging, effectively protecting the battery and extending its working life.
• Sturdy Structure & 4P4S Expandable Design: Made with a high-strength, impact-resistant ABS casing, this 12V 300Ah lifepo4 battery features good heat and weather resistance for steady power supply in different working environments. It supports 4-series and 4-parallel (4P4S) connection, allowing flexible voltage and capacity expansion to meet various high-power demands.
• Wide Application & Important Notes: This deep cycle battery works great as rv battery, rv lithium battery, deep cycle marine battery and kayak battery, widely used in home energy storage, power walls, off-grid systems, solar setups, RVs, campers, marine and industrial backup power. Attention: This lifepo4 battery is intended for energy storage only; please DO NOT use it as a starting battery for engines, golf carts, or other starting devices.
