LFP 306Ah / 285Ah — prismatic LFP cells of increased capacity and life
Country: China · Model: LFP 306Ah / 285Ah
The 306 Ah and 285 Ah cells on LFP chemistry share a common prismatic case of 173.9 × 71.7 × 207.2 mm and differ in operating mode. The 306 Ah version is designed for 0.5P and up to 10 000 cycles, the 285 Ah version for 1P and up to 9000 cycles. Both go into stationary energy storage systems (BESS).

Description
Compared with the 280 Ah cell in the same size, these cells have a larger capacity and a longer life, so a module of unchanged size stores more energy. At 25 °C the 306 Ah cell completes 8000 cycles to 80 % SOH and 10 000 cycles to 70 % SOH, the 285 Ah cell 7000 and 9000 cycles respectively. If the storage system makes one full cycle per day, 10 000 cycles under laboratory conditions correspond to more than twenty years, although calendar ageing is not included in this figure. The 1P version has a smaller capacity but withstands twice the relative current and delivers its full energy in about an hour.
How to choose
The main question in selection concerns the ratio of power to capacity of the storage system. For systems with a discharge of two hours or longer, take the 306 Ah; this version gives more energy in the module and a longer life. The 285 Ah cell is needed where full power has to be delivered within an hour, for example for covering peak loads. If the project allows a shorter life, the same size is available as the LFP 280Ah with 0.5P and 1P versions at 6000 and 5000 cycles to 80 % SOH.

FAQ
What is the cycle life of the 306 Ah cell at 25 °C?
In 0.5P mode, 8000 cycles to 80 % SOH and 10 000 cycles to 70 % SOH are stated, that is, two thousand more than for the 280 Ah cell in the same mode.
Why does the version for 1P mode have a capacity of 285 Ah rather than 306 Ah?
This is a separate version of the cell, designed for twice the relative charge and discharge current, so its rated capacity is lower. Its life is 7000 cycles to 80 % SOH and 9000 to 70 % SOH.
Are the 306 Ah and 280 Ah cells the same size?
Both have a case of 173.9 × 71.7 × 207.2 mm. Before replacing one with the other it is worth checking the terminals and BMS settings, because their capacity is different.
Do the LFP 306Ah / 285Ah cells have a UN38.3 certificate?
Yes, both versions have passed the UN38.3 tests, so they are shipped as lithium batteries with confirmed transport tests.
