"Ich habe während einer Aktion 16 EVE MB31 LiFePO4-Zellen bei BetterESS gekauft und dabei 85 € gespart. Der Versand war schnell, und die Batterien kamen gut verpackt und in einwandfreiem Zustand an. Die Qualität ist ausgezeichnet, mit konstanten Spannungs- und Kapazitätswerten, ideal für meinen 51,2V-Solarsystemaufbau. Der Preis ist für so zuverlässige Zellen sehr angemessen. Ich bin sehr zufrieden und werde definitiv wieder kaufen. Sehr zu empfehlen!"

"I purchased 9 DIY battery cases from BetterESS, and I couldn’t be happier with my decision. The quality of the cases is outstanding – sturdy construction, precise design, and perfect fit for my battery cells. I stacked all nine cases together for my energy storage system, and they work flawlessly. The connections are well thought out, and the setup was straightforward. The seller’s communication was excellent, answering all my questions quickly and professionally. I highly recommend this product."

"I ordered a 15kWh 300Ah LiFePO4 Mobile ESS from BetterESS, and the seller shipped it just 3 days after I placed the order. It was shipped from Germany, which ensured fast delivery within the EU. The entire energy storage system was carefully packed in a wooden crate with foam protection. Now I’ve connected it to my GROWATT inverter, and everything is working perfectly so far. I'm really satisfied with their product and the overall service."
