I would say maybe buy a 2 pack first and see how they work out for you. I have heard very good things about these : https://www.amazon.com/Replacement-Compatible-48-11-2401-48-11-2420-48-11-2411/dp/B07S6G736H/ref=mp_s_a_1_1_sspa?crid=A2ER9P2PH6L9&keywords=m12+cp+3.0&qid=1665225340&qu=eyJxc2MiOiIyLjc1IiwicXNhIjoiMi41MiIsInFzcCI6IjIuMDAifQ%3D%3D&sprefix=m12+cp+3.0%2Caps%2C118&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFERVIyVEZMWUlGSEEmZW5jcnlwdGVkSWQ9QTAwNTg1MjQxQlUzM1c0R1ZaMFNDJmVuY3J5cHRlZEFkSWQ9QTAwMDYwOTkyUVlPMDZFMkcyNjZXJndpZGdldE5hbWU9c3BfcGhvbmVfc2VhcmNoX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= and they work out to a little less than half the price of the ones you posted. Check the reviews. I don't own any aftermarket batteries, I already have like 7 m12 batteries that came with various tools (mostly 2.0's) but will consider these when mine start dying
