48V Lithium-ion battery

Delta Lithium-ion battery is an excellent energy source with a long service life for 48V applications such as telecom and datacenter for power backup. It is a compact package of high energy density to save space and weight.

Its maintenance-free design couples with the intelligent remote monitoring function and can eliminate on-site maintenance efforts and save considerable operational costs and then contributes to lower TCO (Total Cost of Ownership) compared with conventional batteries.

For safe and reliable operation, Delta’s advanced BMS (Battery Management System) can protect the function to protect the battery

against abnormal conditions, like over-temperature, over-charging, and over-discharging. BMS can also make the battery operations more optimal to serve over long term.
