Energy Cell
A large-format 314 Ah lithium iron phosphate (LFP) prismatic cell, the building block behind our liquid-cooled packs, C&I cabinets and utility-scale containers.
314 Ah of LFP, in a single prismatic cell.
The Energy Cell is a large-format prismatic lithium iron phosphate cell rated for at least 314 Ah across a 2.8 to 3.55 V working window. With an internal resistance of 0.25 mΩ or less, it supports 157 A standard and up to 314 A maximum sustained charge and discharge current at 25°C ambient.
Measuring 71.8 x 207.1 x 174.2 mm and weighing 5.65 kg, it is the cell format at the heart of the Energy Pack and our Day and Dusk systems. It charges from 0 to 55°C, discharges from -20 to 55°C, and holds its charge in storage with a monthly self-discharge rate of 3.5% or less.
Technical Specifications.
Rated at 0.5C discharge between 2.8 and 3.55 V, 25±2°C, new cell.
Maximum sustained charge and discharge current at 25±2°C ambient.
Measured at 1 kHz, keeping energy loss low under load.
Cell Specs Sheet
Built for Performance
High Capacity
At least 314 Ah per cell at 0.5C discharge, packing more energy into every cell position of a pack.
Sustained 314 A
Handles 157 A standard and up to 314 A maximum sustained charge and discharge current at 25°C ambient.
Low Internal Resistance
An internal resistance of 0.25 mΩ or less at 1 kHz keeps heat generation and energy loss low under load.
Wide Temperature Window
Charges from 0 to 55°C and discharges from -20 to 55°C, with no more than 3.5% self-discharge per month in storage.
