Let down

1. This battery has no communications port or cable, so it can not communicate with the inverter. This should be disclosed in the description. 2. After one month of use, I have now confirmed that usable energy is about 10.6kWh. Nowhere near 15kWh. (13kWh should be attainable if this was a 15kWh battery pack). 3. Old, probably used cells. Resting voltage of 53.5 to 53.7. It should be resting closer to 54.1v for new cells. Dated 2022 on the pack, yet sold as new in 2026. I would not recommend this to anyone. I would not use it for a client. 2 stars because at least it is charging well and discharging consistently to that 10.6kWh range while not overheating, and looking good doing it.
