FLYFINE LiFePO4 BATTERIES

12.8V Metal Case LiFePO4 Battery

The FLYFINE metal case battery series combines LiFePO4 chemistry with an integrated battery management system. Five capacity options cover 100Ah to 314Ah for compatible 12V-class systems.

Select rated energy from 1.28kWh to approximately 4.019kWh. Maximum charge and discharge currents are 100A for the 100Ah and 150Ah batteries, and 150A for the 205Ah, 300Ah and 314Ah batteries.

Key Features

Metal Enclosure

A metal case provides the battery housing. The illustrated 100Ah model features a carrying handle and covered terminals.

Integrated BMS

An integrated battery management system supports battery monitoring and management.

Five Capacity Options

Choose 100Ah, 150Ah, 205Ah, 300Ah or 314Ah according to your energy and load requirements.

6,000-Cycle Rating

The datasheet lists 6,000 cycles at 80% depth of discharge. Actual service life depends on operating conditions.

Rated energy and current limits follow the linked FLYFINE datasheet. The working temperature range is not a separate charging temperature specification. Confirm charging conditions and charger settings for your selected battery.

Select the Right Battery

Choose capacity according to your required runtime, then check that the battery current rating supports your equipment. A larger capacity does not always mean a higher discharge current.

For example, the 300Ah and 314Ah batteries provide more rated energy than the 205Ah battery, while all three have the same listed maximum discharge current of 150A.

Frequently Asked Questions
