I purchased five of these to run in a series to create a 15S 49.5v 8.4Ah pack for my e-bike project. After about 3 months of use and 16 cycles, these packs do deliver for LiFePO4. The sag doesn't drop below 40v until after about 5.5-6Ah of use. I typically don't discharge it any further than that to keep the packs healthy.
The only real negative here, as is with all LiFePO4, is the size and weight comparison to LiPo. A 12S2P 44.4v 16Ah LiPo battery is one less battery pack and almost twice the capacity. Of course it costs twice as much, but if you were to go with a 12S 44.4v 8Ah set up, it would only be two battery packs and half the weight of five of these LiFePO4 batteries at similar cost.
Anyhow, these LiFePO4 batteries are good for those who are learning about voltages, charging, and discharging. They're safe chemistry and great for beginners. I have no idea how many cycles these things will last. In theory, they should last substantially longer than LiPos. We'll see in time.
