This 48V 18Ah LiFePO4 battery is the most common plug-and-play method for providing 48V to the MotoCrane RADICAL and ULTRA PSU (Power Supply Unit). Lithium Iron Phosphate battery chemistry offers higher discharge rates than Lithium Ion without the balance charging hassles/safety concerns of Lithium Polymer (LiPo). The battery comes terminated with a gray Anderson SB50 connector, directly compatible with the cable set included with your remote arm. 865Wh capacity provides 8-10hours of run time (dependent on motor use/duty). Using the included 3 amp charger, it takes ~6 hours to recharge after fully depleted, and does not require any balance charging.
