+PROS · 4
Top score in our Guides test set
Consistent performance under rated load — no thermal throttling observed
Verified genuine sourcing via the listed merchant
Drop-in compatible with common fixtures

Priced above budget alternatives
Fewer authorised sellers — buy from reputable channels only
Not ideal for edge-case use outside rated draw
◦ CAUTION / LI-ION SAFETY
Never exceed rated continuous draw on a guides cell.
Overdriving lithium cells past their rated continuous current can vent, catastrophically fail, or start a fire. If a listing advertises specs that defy physics (e.g. 9,800 mAh in an 18650 form factor), walk away. Buy from authorised sellers only.
