A UK energy-storage startup is aiming to take on Tesla Inc in the competition to outfit homes with affordable back-up battery power.
Powervault Ltd is preparing to boost production of its lead- and lithium-ion batteries, said managing director Joe Warren. The London-based company is targeting sales of 50,000 units a year by 2020, up from about 1,000 this year, he said.
