EGO Power+ 56V 4.0 Ah ARC Lithium Battery with Fuel Gauge

Got a spare EGO 4.0Ah battery here. It's the ARC Lithium version so it stays cool while you're working. Has the built in fuel gauge so you actually know how much juice is left before it dies on you. Works with all the EGO 56V tools, blowers, mowers, whatever you got. Pretty much essential if you have a bigger yard and dont want to wait for a recharge mid-job. Asking $130 obo paid over $270
