How Does a 12V 300Ah LiFePO4 Battery Deliver Reliable Power?
A 12V 300Ah LiFePO4 battery provides approximately 3.84 kWh of energy, offering long cycle life, fast charging, and advanced safety features. It is ideal for RVs, solar energy systems, marine use, and off-grid applications, providing lightweight, maintenance-free, and reliable power with smart BMS protection and Bluetooth monitoring.
What are the key specifications of a 12V 300Ah LiFePO4 battery?
This battery features a nominal voltage of 12.8V and a capacity of 300Ah, delivering about 3.84 kWh of energy. Typical dimensions are 521 x 237 x 218 mm, weighing around 28.5 kg (62.8 lbs). It supports continuous discharge currents up to 200A and peak currents up to 400A for short bursts. The battery uses EV-grade LiFePO4 cells with low internal resistance. The casing is ABS plastic with an IP65 rating. Communication options include Bluetooth, RS485, and CAN bus. The integrated Battery Management System (BMS) provides comprehensive protection including overcharge, over-discharge, overcurrent, overheating, and short circuit protection.
How long can a 12V 300Ah LiFePO4 battery last on a single charge?
Depending on load and usage, this battery can last 8 to 12 hours. For example, at a continuous draw of 50A, it provides about 6 hours of operation (300Ah ÷ 50A). Runtime varies with application and environmental factors.
What advantages do LiFePO4 batteries offer over traditional lead-acid batteries?
LiFePO4 batteries are lighter (about 70% lighter than lead-acid), have higher energy density, longer cycle life (over 4000 cycles at 100% depth of discharge), faster charging, and superior thermal stability. They require zero maintenance and provide consistent voltage output, reducing downtime and operational costs.
How does the Battery Management System (BMS) improve safety and performance?
The BMS continuously monitors voltage, current, temperature, and state of charge, protecting the battery from overcharge, over-discharge, overheating, overcurrent, and short circuits. It balances cell voltages, extends battery life, and triggers alarms or shutdowns under unsafe conditions.
What are the optimal charging and discharging parameters for this battery?
Charging is recommended between 0°C and 50°C with a maximum charge current of 60A. Discharging is effective from -20°C to 60°C, supporting continuous discharge currents up to 200A and peak currents up to 400A.
How long is the typical lifespan and cycle life of a 12V 300Ah LiFePO4 battery?
This battery typically offers over 4000 cycles at 100% depth of discharge, translating to a lifespan of 10 years or more, significantly outperforming lead-acid batteries.
What applications are best suited for a 12V 300Ah LiFePO4 battery?
Ideal for RVs, solar power storage, marine applications, off-grid cabins, portable power stations, and industrial backup systems, this battery delivers reliable, lightweight, and maintenance-free power.
How does Bluetooth or communication protocol enhance battery monitoring?
Integrated Bluetooth and communication protocols such as RS485 and CAN bus enable real-time monitoring of battery health, voltage, current, and temperature via mobile apps or remote systems, facilitating proactive maintenance.
What benefits does built-in heating provide?
Built-in heating ensures optimal battery performance in cold climates by maintaining cell temperature, preventing capacity loss and improving charging efficiency in low temperatures.
How does the battery’s lightweight design improve usability?
The lightweight design simplifies installation and handling, reduces overall system weight, and improves energy efficiency and mobility for portable and vehicle-mounted applications.
