Hi all. I have several EGO Power+ items (self-propelled steel deck mower, backpack blower, snow blower, power head with multiple attachments, etc.). As a result, I already have 4 each 7.5 amp batteries and 1 each 5.0 amp battery. I know the batteries are expensive and likely make up a decent portion of the cost of these devices. Since I already have 5 batteries, is this new Nexus Power Station available to buy without the batteries? The unit is rather expensive and since I already have 5 batteries, I'd like to save a few $$$ and still get the Nexus Power Station. EGO already sells mowers without having to buy the batteries, so do you have the same option with the new Nexus Power Station? Thanks!
