Lithium Ion batteries (LEGIT!!!)

Regarding that lithium ion is still new technology for most people in Africa, My friend referred me to this company The Solar Shop, at first I thought it was a scam, how could they sell these batteries for so cheap, but it turned out legit, I have bought x6 4,8kwh lithium Ion Batteries and have installed them, they are working Amazingly. Thanks Gareth for the great assistance.
