STORAGE
Rolls R-Series & S-Series drop-in LFP batteries should be stored in an environment with
temperatures between -5°C (23°F) and 45°C (113°F). 20°C (68°F) is recommended.
If seasonally stored in a space which will fall below -5°C (23°F), it is recommended to
discharge the battery to between 60-80%, disconnect the battery from any external system
and store the battery in an alternative location above -5°C (23°F).
Rolls drop-in LFP batteries self-discharge and should be charged, at minimum, once per
year, even when in distributor stock or storage. For temperatures above 40°C (104°F) the
battery should be charged every 3 months. Do not store Rolls R-Series & S-Series drop-in LFP
batteries at temperatures above 45°C (113°F).
INSTALLATION
Rolls R-Series & S-Series drop-in LFP batteries may be installed in any orientation*
(except upside down) as required by the application. Rolls drop-in LFP batteries must
be installed in an indoor space and out of direct sunlight.
*Front Terminal (FT) models are installed on one side only. Refer to the label for which.
All installations should consider the ambient temperature. If installed in a region with
freezing temperatures or extreme heat, special care should be given. Rolls R-Series
drop-in LFP batteries cannot be charged below 0°C (32°F), nor discharged below
-20°C (-4°F) and doing so will severely degrade the internal cells. Similarly, operation
above 55°C (131°F) will negatively impact longevity, performance, and safety. Rolls
S-Series drop-in LFP batteries feature internal heating to compensate for reduced
temperatures but are still limited in the external temperatures they can tolerate. Refer to
the datasheet or label of your specific model for accurate information.
Waking up the Battery
If you have just received your battery, it may have entered a low power sleep mode during
transit. In this state, the Bluetooth receiver will be off, and the voltage will be between 2V-10V,
waiting to sense an external device. For R-Series drop-in LFP models, connect a charger or
load to “wake up” that unit and enable charging, discharging, and a Bluetooth connection. To
wake up an S-Series drop-in LFP battery, do this, or press and hold the reset button located
below the onboard screen.
TERMINAL TORQUE
Terminal connections must be properly torqued. Rolls R-Series & S-Series drop-in LFP
batteries using M8 fasteners should be torqued to 10-12Nm.
DO NOT OVERTORQUE: In the event of a damaged terminal, do not attempt to repair
the terminal. Do not use the battery if the recommended torque cannot be met.
