Frequently Asked Questions

11.8 kWh of nominal energy at 51.2 V, from a 230 Ah LiFePO4 pack. Depth of discharge is a separate rating of ≥95%, and that is what governs how much of the 11.8 kWh you actually draw.

15 units, for a maximum system capacity of 176.6 kWh. Each unit contributes 11.8 kWh at 51.2 V and coordinates with the rest over CAN or RS485.

150 A continuously, which is also the recommended charge and discharge current, with a 200 A peak for 15 seconds. In power terms that is 7500 W recommended and 10000 W at peak.

≥6000 cycles is the rated cycle life, and the FLA48230 carries a 5 Years warranty. Charge it from 0 to 55 °C and discharge it from -20 to 55 °C, inside the 44.8 V to 57.6 V operating window.
