I ordered 16 Grade A LiFePO₄ cells for my home solar storage project. The batteries arrived well packaged, and every cell had very consistent voltage readings. Installation was straightforward, and they've been performing reliably for several months. Communication with the Fench Energy team was quick whenever I had questions. Overall, I'm very satisfied with both the product quality and the customer service.

We've purchased battery cells from several suppliers over the years, and Fench Energy has been one of the most reliable so far. The actual capacity matched the specifications, and the cells were clean and well balanced. Shipping from the EU warehouse was faster than expected, which helped us finish our installation on schedule. I would definitely consider ordering again.

The packaging was excellent, with every battery securely protected during transport. I appreciated receiving testing information before shipment, which gave me more confidence in the purchase. After installing the battery pack in my off-grid cabin, the system has worked flawlessly. Great value for the price and professional support throughout the ordering process.

I was initially hesitant about ordering batteries online, but the experience turned out to be very positive. The team answered all of my technical questions promptly, and delivery was smooth. The batteries perform exactly as described and work perfectly with my inverter. Everything from ordering to installation was much easier than I expected.
