It is ideal for solar energy systems, electric vehicles, marine and portable power applications, offering lightweight design and Bluetooth monitoring for enhanced reliability and user experience.
What are the key specifications of a 12V 50Ah LiFePO4 battery?
This battery features a nominal voltage of 12.8V and a capacity of 50Ah, delivering about 640Wh of energy. Typical dimensions are around 229 x 138 x 208 mm, weighing approximately 6.2 to 7.8 kg. It supports continuous discharge currents up to 50A and peak currents up to 100A. The casing is ABS plastic or metal with IP65 to IP67 rating. Communication protocols include Bluetooth, RS485, and CAN bus. The integrated Battery Management System (BMS) provides overcharge, over-discharge, short circuit, and temperature protection.
How long can a 12V 50Ah LiFePO4 battery last on a single charge?
Depending on load and usage, this battery can last 4 to 8 hours. For example, at a continuous draw of 20A, it provides about 2.5 hours of operation (50Ah ÷ 20A). Runtime varies with terrain, speed, and load.
What advantages do LiFePO4 batteries offer over traditional lead-acid batteries?
LiFePO4 batteries are lighter, have higher energy density, longer cycle life (2500 to 7000 cycles depending on depth of discharge), faster charging, and superior thermal stability. They require less maintenance, have enhanced safety features, and provide more usable capacity.
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, 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 45°C with a maximum charge current of 25A. Discharging is effective from -20°C to 60°C, supporting continuous discharge currents up to 50A and peak currents up to 100A.
How long is the typical lifespan and cycle life of a 12V 50Ah LiFePO4 battery?
This battery typically offers 2500 to 7000 cycles depending on depth of discharge, translating to a lifespan of 8 to 10 years, significantly longer than lead-acid batteries.
What applications are best suited for a 12V 50Ah LiFePO4 battery?
Ideal for solar energy storage, marine and RV power, electric scooters, portable power stations, and backup power, this battery delivers reliable, lightweight, and maintenance-free power.
How does Bluetooth or communication protocol enhance battery monitoring?
Integrated Bluetooth and communication protocols like RS485 and CAN bus enable real-time monitoring of battery health, voltage, current, and temperature via apps or remote systems, enabling proactive maintenance.
What benefits does lightweight design provide?
The lightweight design reduces overall system weight, making installation and handling easier while improving energy efficiency and device performance.
How does temperature protection improve battery performance?
Temperature protection prevents charging or discharging outside safe temperature ranges, avoiding damage and extending battery life. Some models include built-in heaters for cold climate operation.
What environmental conditions can a 12V 50Ah LiFePO4 battery withstand?
Designed for rugged use, this battery operates reliably between -20°C and 60°C and features IP65 or IP67 rated enclosures for dust and water resistance.
