Telecom infrastructures are connecting our society, but power outages could be a disaster because even the smallest fluctuation in power could result in communication blackouts or network failures. Investing in a telecom battery backup system is always one of the priorities for telecommunication operators in the 5G era. Sunwoda 48V telecom batteries have a capacity covering 50Ah-150Ah, which can easily meet the power backup needs of macro and micro base stations.
