KAIMEIWEI 12.8V 400Ah RV Battery Lithium Iron Phosphate LiFePO4 Batteries Rechargeable High Capacity
12V 400Ah Li-ion batteries use powerful, high energy density A-grade cells, with a typical service life of more than 10 years under normal use conditions. In addition, their self-discharge rate is kept below 2.5‰, ensuring minimal loss when not in use. Lithium batteries are highly compatible and have a battery management system that can communicate with solar inverters or smartphones via Bluetooth. The weight is only 1/3 of the lead-acid battery of the same capacity, providing greater convenience for transportation. In addition, they are equipped with M8 terminals and bolts. This battery is gradually replacing lead-acid batteries and is used in various applications such as electric scooters, backup power for medical equipment, solar energy storage systems, marine batteries, single-battery RV systems, electric vehicles, etc.
Features:
1. Stable chemical properties: Lithium iron phosphate materials are resistant to high temperatures, non-flammable and non-explosive, and the risk of thermal runaway is much lower than that of ternary lithium batteries.
2. No toxic substances: environmentally friendly and free of heavy metal pollution.
3. Long cycle life: more than 2,500 cycles, the number of charge and discharge times far exceeds that of lead-acid batteries (about 300-500 times), and the life span can reach 5-10 years.
4. Slow capacity decay: full charge can still maintain a high capacity (more than 80%).
5. High energy density: small size, light weight, saving RV space.
6. High current charging and discharging: supports fast charging and high-power electrical appliances (such as air conditioners, induction cookers).
7. -20℃~60℃ operation: low temperature performance is better than ordinary lithium batteries (heating module is required to cope with extreme cold).
8. BMS protection: overcharge/over-discharge/short circuit/over-temperature protection, balanced battery cells, and extended life.
