Fan Cart Replacement Battery
Lithium-polymer battery, 7.4 V 1250 mH replacement for PASCO’s Fan Carts.
A high energy density lithium-polymer replacement battery which can run the fan continuously at medium thrust for about 1.5 hours before the ‘low-battery’ LED begins to flash. Since the battery recharges quickly (typically in one hour), even short periods (10 – 20 minutes) with the charger plugged in will recharge the battery sufficiently.
