May 24, 20233 yr CFE batteries are pathetic. I do not recommend anyone to purchase this junk battery. Their support is very poor. Their app is very basic and has poor functionality. They did an upgrade of my battery firmware yesterday and now all 4 x5.1kW batteries charge from 0-100 in 10min and discharge from 100-0 in 10 min. Business was closed yesterday during 4 hours of loadshedding. Don’t buy CFE unless you want to suffer.
