Telone also requires lithium-ion battery storage that is capable of 4,500 cycles on 90% discharge depth, working on 48 V. Battery capacity must be 96 kWh for Chitungwiza, Hatfield and GlenView, and 48 kWh for the Telone Center for Learning. They must support parallel scalability, include LED charging indicators and are housed in lockable cabinets with a 10-year warranty.
