STORAGE

Rolls LFP batteries have operating and storage temperature limitations. These should be followed to ensure the battery remains in good working order and to prevent the possibility of cell and component damage or failure. Rolls LFP batteries include cylindrical or prismatic cell types as well as various electronic components. As a result, storage temperature limits may vary by battery model as outlined.

For optimal performance, Rolls recommends storing R48-100LFP ESS batteries in ambient temperatures between -5°C (23°F) and 35°C (95°F).

Rolls manufacturer warranty terms for R48-100LFP ESS batteries also require storage in temperatures above -15°C (5°F) and no higher than 35°C (95°F) in line with component limitations. Product damage or failure due to extended exposure to temperatures at or outside this range would not be covered under warranty.

Rolls R48-100LFP ESS batteries do self-discharge and should be charged once per year, at minimum, when stored for extended periods. For temperatures above 25°C (77°F) the battery should be charged every 3 months as self-discharge rates increase in warmer temperatures. Do not store Rolls R48-100LFP ESS batteries at temperatures above 35°C (95°F).

In cold climates, charge/discharge the battery to between 60-80% state of charge, disconnect from any external system, and store the battery off site, above -5°C (23°F).

For seasonal applications, Rolls R48-100LFP ESS batteries should not be left connected to an offline system or disconnected and stored in a space where ambient temperatures may fall below the -15°C (5°F) or above 35°C (95°F).

NOTE: Ensure the breaker and BMS are OFF during storage.
