What it 12.8V 120Ah LiFePO4 Rechargeable batteries?
- It’s a rechargeable battery delivering 12.8 volts (nominal voltage) with a capacity of 120 ampere-hours (Ah).
- LiFePO4 stands for Lithium Iron Phosphate, which is the battery chemistry used.
- Deep cycle refers to its ability to discharge a high percentage of its capacity repeatedly over many cycles.
- Waterproof means it is sealed against water damage.
Why choose this 12.8v 120Ah LiFePO4 battery:
Here are key Features Of 12.8v 120ah LiFePO4 Battery Pack:
- Longer service life: You mentioned 3000 cycles and a 7-8 year lifespan, which is significantly longer than lead-acid batteries that typically last around 500 cycles and 3-5 years. This translates to fewer battery replacements and lower overall costs.
- Plug-in replacement for lead-acid batteries: Since the voltage is the same (12.8V), these LiFePO4 batteries can be directly installed in place of existing lead-acid batteries without modifying the charging system.
- High discharge rate capability: The ability to deliver high currents (175A continuous, 320A peak) makes them suitable for powering devices with high surge currents, like motors found in power tools and some appliances.
- Support for parallel and series connection: This allows for increased voltage or capacity depending on your needs. By connecting batteries in series, you can increase the voltage (e.g., connecting two 12.8V batteries in series will provide 25.6V). Parallel connection increases the capacity (e.g., connecting two 120Ah batteries in parallel will provide 240Ah at the same voltage).
- Fast charging: Recharging in 1-3 hours compared to several hours for lead-acid batteries is a significant advantage, especially for applications where downtime is undesirable.
- Lighter weight: Lighter weight is a major benefit, particularly in mobile applications like RVs, boats, and even drones where weight reduction is crucial.
- Maintenance-free: Unlike lead-acid batteries, which require periodic maintenance like topping up electrolytes, LiFePO4 batteries require no such maintenance, saving time and effort.
- Low self-discharge rate: At less than 3% per month, the self-discharge rate is minimal, so you can store the battery for extended periods without significant capacity loss.
- Deep cycle capability: The ability to be deeply discharged (up to 100%) makes them ideal for applications requiring full use of their capacity, unlike some other battery types.
- Waterproof rating: An IP65 rating signifies protection against water ingress, making them suitable for marine environments or applications exposed to moisture.
- Safety: As you mentioned, LiFePO4 chemistry is one of the safest forms of lithium-ion batteries due to its inherent stability, reducing the risk of fire or explosion.
Overall, 12.8V 120Ah LiFePO4 batteries offer a compelling combination of features that make them a superior choice for many applications compared to traditional lead-acid batteries.
