Good quality batteries

Ordered a 12.8kWh Li-ion Battery Pack from this guys and it came in perfect condition, I have been using the set since 2019 on my Axpert Mk11 Inverter also referred some of my colleagues to buy from them and their systems are working perfect, but now I see they have a sale. I might as well buy another one before they run out of stock. Will give them 5 stars when my warranty finishes
