Storage - R-Series, G-Series & S-Series LFP Drop-in Replacement Models

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 LFP batteries in ambient temperatures between -5°C (23°F) and 45°C (113°F).

Rolls manufacturer warranty terms for R-Series, G-Series & S-Series LFP drop-in batteries also require storage in temperatures above -5°C (23°F) and no higher than 45°C (113°F) in line with battery component limitations. Product damage or failure due to extended exposure to temperatures at or outside this range would not be covered under warranty.

Rolls R-Series, G-Series & S-Series LFP drop-in batteries do self-discharge and should be charged once per year, at minimum, when stored for extended periods. For temperatures above 40°C (104°F) the battery should be charged every 3 months as self-discharge rates increase in warmer temperatures. Do not store Rolls S48-100LFP STACK-LV batteries at temperatures above 55°C (131°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 R-Series, G-Series & S-Series LFP drop-in batteries should not be left connected to an offline system or disconnected and stored in a space where ambient temperatures may fall below the -5°C (23°F) or above 45°C (113°F).

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