i just know that battery pack costs in EVs are like $100 / kwh so 10 AH X 50V = 500 WH or 0.5 KHW should be $50 yet it is $500.

so i know they're marking up by 10X. even the fake one at $150 is still marked up 3X which is fairly healthy markup.

i think at $150 they can perfectly afford to use any cells they want. whereas $500 is just a scam.

they just feel like if you already bought the tool now you have no choice but to pay whatever they ask - except i do have a choice.

i don't think there are any EGO commercial batteries that are different from regular EGO batteries ... my charger is sold as both a commercial ( with 2 year commercial warranty ) and residential ( with 3 year warranty ) for the same unit, and the mower is only sold as commercial ( with 2 year commercial warranty )

but yes i heard genuine EGO batteries tend to die just out of warranty, which is consistent with the whole scam where they sell you an excellent tool at a reasonable price and then rape you on the batteries.
