The **C Worth Energy 25.6 V 100 Ah (≈ 4 kWh)** battery is a lithium-iron phosphate (LiFePO₄) deep-cycle energy storage unit. With a nominal voltage of 25.6 V and capacity of 100 Ah, it delivers about 2.56 kWh useful energy (but in practice pack designs often allow ~4 kWh when configured or marketed). It features a built-in battery management system (BMS) for cell balancing, over-charge/discharge protection, and often supports parallel expansion.
