7.3.4
Float voltage
If the battery module is to be placed on a float charge, maintain a voltage between 55.2 and 56 Volts.
For systems (such as uninterruptable power supplies) that will see the batteries floated for extended
periods of time, the batteries should be cycled (at least to DoD 10%) and then charged as a minimum
annually. For best performance a six monthly test is highly recommended.
7.4
Discharging the Battery Module
The discharge characteristics described below are to achieve maximum number of cycles/life of the
battery module.
7.4.1
Battery module discharge current (0.5C)
19.2 Amps (for model GC48V-040LFP-2RU)
28.8 Amps (for model GC48V-060LFP-2RU)
It should be noted that the modules can both deliver up to 60Amps (1C) if required
7.4.2
When to charge a discharged module
While the battery module is protected by the BMS to prevent excessive battery module discharge, it
is recommended to recharge the battery module as soon as practical following a discharge event.
7.5
Storage
The battery module should be stored, fully charged in an area that is protected from the elements and
at an ideal temperature of 20C and low humidity. It should be stored in its original packing.
At least annually, the battery should be charged in accordance with Section 7.3 of this manual
If storing a battery for an extended period of time, reference should be made to the “Self Discharge”
characteristics as indicated in the table of specifications.
It should also be noted that, a battery module that has been stored for an extended period of time
may exhibit a loss of capacity when it is first placed into service. This ‘loss of capacity’ can normally be
corrected by cycling the battery at least three times.
