The Galaxy Buds 2 will sport Bluetooth LE connectivity and the matching charging case (model number EP-QR177) depicted here sports a 500mAh battery, while the Buds 2 add 120mAh to the mix combined, so whatever battery life Samsung announced, there will be 4x that in the charging case.
You'll need it, given the extra battery drain that ANC usually entails. For comparison, while the OG Buds had the same about 60mAh pack per bud, their case has a much much smaller battery at 252mAh.
