Its lithium iron phosphate chemistry ensures safety, lightweight design, rapid charging, and durability, outperforming traditional lead-acid batteries.
What are the key specifications of a 12V 18Ah LiFePO4 battery?
This battery has a nominal voltage of 12.8V and a capacity of 18Ah, delivering approximately 216Wh of energy. Dimensions typically measure around 140 x 115 x 75 mm, weighing about 2 to 3 kg. It supports continuous discharge currents up to 20A and peak currents up to 50-60A for short bursts. The battery casing is usually ABS or PVC with an IP64 or higher rating for water and dust resistance. Communication protocols like RS485, CAN, and Bluetooth are often integrated. The Battery Management System (BMS) provides protection against overcharge, over-discharge, short circuit, and temperature extremes.
How long can a 12V 18Ah LiFePO4 battery last on a single charge?
Depending on the load, this battery can last between 6 to 12 hours. For example, at a continuous draw of 10A, it provides about 1.8 hours of operation (18Ah ÷ 10A). Runtime varies with usage, temperature, and application type. LiFePO4 batteries maintain about 95% efficiency, offering longer usable capacity than lead-acid batteries.
What advantages do LiFePO4 batteries offer over traditional lead-acid batteries?
LiFePO4 batteries have higher energy density, longer cycle life (over 3000 to 5000 cycles at 80% depth of discharge), faster charging, and superior thermal stability. They are safer, lighter (about half the weight of lead-acid), maintenance-free, and provide consistent voltage output throughout discharge, reducing downtime and improving performance.
How does the Battery Management System (BMS) improve safety and performance?
The BMS continuously monitors voltage, current, temperature, and state of charge, protecting against overcharge, over-discharge, overheating, and short circuits. It balances cell voltages to extend battery life and triggers alarms or shutdowns if unsafe conditions arise, ensuring reliability and safety.
What are the optimal charging and discharging parameters for this battery?
Charging typically occurs between 0°C and 45°C with a maximum charge current of 3-5A. Discharging is effective from -20°C to 60°C, supporting continuous discharge currents up to 20A and peak currents up to 50-60A for short bursts. Following these parameters optimizes battery lifespan and performance.
How long is the typical lifespan and cycle life of a 12V 18Ah LiFePO4 battery?
This battery offers over 3000 to 5000 charge cycles at 80% depth of discharge, translating to about 8 to 10 years of typical use. This is significantly longer than lead-acid batteries, reducing replacement frequency and total cost of ownership.
What applications are best suited for a 12V 18Ah LiFePO4 battery?
Ideal for e-bikes, electric scooters, solar power systems, portable power banks, backup power, robotics, and small-scale energy storage, this battery delivers reliable, lightweight, and maintenance-free power for diverse uses.
