Lithium (LiFePO4) batteries
FIBER OCEAN FO-LB lithium iron phosphate batteries deliver long cycle life, high round-trip efficiency and a compact footprint. Indoor 48 V rack modules (100–205Ah), outdoor IP65 48 V cabinets and 12.8 V blocks with an integrated BMS cover telecom backup, UPS and energy storage.
Key applications: telecom and 5G backup, TowerCo sites, UPS energy stores, hybrid and solar storage, edge and access sites.
Why FIBER OCEAN lithium
Long cycle life
LiFePO4 cells rated from 2000 to 6000 cycles depending on model, with a design life up to 15 years.
Integrated smart BMS
Cell balancing, protection and monitoring over RS485, CAN or dry contacts; a 12.8 V block adds a Bluetooth BMS for app monitoring.
Rack, block & outdoor
19″ rack modules, standalone 12.8 V blocks and IP65 wall/pole outdoor cabinets from −40 to +55 °C.
