Great battery capacity in a minimal size (12V 314Ah Smart Bluetooth Mini). The battery was delivered quickly and well packaged that eliminated any damages in transit.
Patrik NilsonThe Wattcycle 12V 628Ah battery is absolutely fantastic. Performance has been flawless, and it’s clear the product is built with quality in mind. Unfortunately, the shipping process through FedEx was not handled with the same level of care. The battery arrived with a slightly damaged corner, clearly the result of being dropped or mishandled during transit. The packaging from Wattcycle was very good, but it simply couldn’t withstand the abuse from FedEx.I was concerned about possible internal damage, so I reached out to Wattcycle customer support. Talia responded to my emails quickly, professionally, and with genuine concern. The support team guided me through the entire process and made sure I felt confident about the condition of the battery. She replied to every email quickly and made the whole situation stress‑free. Her professionalism and kindness really stood out, and she deserves a lot of praise. Wattcycle Customer Support was exceptional and deserves recognition.Despite the shipping issues, I’m extremely happy with the product and the customer service. I would absolutely buy from Wattcycle again. My only wish is that they consider using a different shipping company, as nearly every FedEx package we receive arrives damaged.
Read MoreI purchased 12 100ah LiFePO4EV Grade A cells. I first reached out to confirm that there were actually 12 cells as Watt cycle was only charging $17.99 per cell. Jennifer at watt cycle confirmed that I would get all 12 which I did. They did come one a battery housing which needed to be removed and 8 of the cells looked brand new and were at 3.2 volts which is the typical voltage of new LiFePO4 shipped new from the factory. The other four were all the way down to 2.5 ~ 2.6 volts and the cells were swollen. I also checked the QR code and it appeared they were manufactured two or three years ago. I brought this up to Jennifer and provided pictures showing the swollen cells and she's arranged for four new grade A 100ah cells to be delivered to replace the defective cells. Great price and great customer service.
Read MoreI ordered two batteries for now, and they were delivered in less than a week. Both work perfectly. I bought them to expand the capacity of my EcoFlow system using the well-known "hack". Battery factory settings allow you to use the full 100% of the capacity with this unofficial EcoFlow expansion setup.I was also pleasantly surprised to discover that these were not old batteries being cleared out, but completely new units manufactured in April 2026, with cells produced in autumn 2025. They also feature an updated design and more durable triple-layer cardboard packaging, which greatly reduces the risk of damage during transportation.
