They are commanding an insane price for the MX batteries. They are just run of the mill 21700 3000mAh cells. Not junk, but not proprietary either. I'm going to guess Samsung brand like their M18 HO packs. I understand the packs themselves are built beefier, but I feel like they could've done a 4x M18 platform and beefed up the battery areas on the "equipment"

D) themselves if they were that concerned about the abuse that this kind of "equipment"

D) would see. Maybe include a vented rubberized cover with straps to cover and hold down the M18 backs better. No doubt the performance will be impressive, but make not mistake the MX line was set up this way to get every last penny out of their customers.
The generator would be cool to have, but not when two 6.0 MX packs will exceed $1k. It's annoying because I feel like I have enough M18 packs to power my own microgrid! The last thing I need is another battery.
