Reputable brands? I'd say Fenix. The highest rated capacity ones I've seen and the most convenient seem to be Epoch brand ones: https://www.18650batterystore.com/collections/aa-batteries/products/epoch-aa-usb-4packThanks, All,
I just like to highlight that Eneloop is MiMH batteries, and it may not suit wireless mic usage, as they are high power drainer. Therefore, I am looking for Rechargables Li-ion 1.5V batteries. These Li-ion 1.5V batteries are relatively new, so I just like to know what are the more reputable brand.

Charge 4 at a time in 2 hours off of USB and are rated at 2300 mAh or 3450 mWh. These are the highest capacity rated ones I've found. They can be discharged up to 1.5 amp rate. Many brands are only rated around 1600 mAh. However, Eneloop Pro batteries are rated at 2550 mAh. Those are NiMH. Unless you need the convenience of the USB charging, Eneloop Pro batteries will likely outlast your lithium ion AAs per charge. 14500 cells are different. They are 3.7 volts. Unprotected ones may discharge as high as 10 amps, 4 amps for good protected ones. Lithium ion 1.5 volt AAs are different as they have to be protected because they require circuitry to drop the voltage. You will have a hard time finding lithium ion AAs that can beat Eneloops or Eneloop Pros for their discharge rate. I have drained regular eneloops at 4 amps before (lithium disposable AAs are only rated at 3 amps).
Thanks for the feedback and suggestion. I am using both Shure beta 58A and SLX1.Wireless battery life will vary depending on the actual product. Do you have a model in mind, and does the manual not list run time estimates? Most manuals list run times for AA alkaline and AA NiMH if they use those, typically using 2k-mAh Eneloops, not Pros. I usually see run times of about 20% less on regular Eneloop vs. alkaline. Pros would probably run close to alkaline, but may not recharge consistently or for as many charge cycles. Discharge current is not a factor with wireless packs.
Personally, I use regular Eneloops in several Shure PGX-D beltpacks and I recall they could go about 6 hours. If you run all day, change them at lunchtime. Eneloops are a known, safe quantity, where Li-Ion quality and performance in AA applications is not, IMO.
