Jnfkldsb 8.0Ah Compatible with DeWalt 20V Max Battery
Tier Cby Jnfkldsb
Good performance across the board mainly due to great 18650 cell use, but the electrical construction is poor and the case will melt plastic onto your tool under high-power use. Cannot recommend over more robust designs like xiuqiyu or waitley.

Actual capacity 3.85Ah. 8.0Ah is a complete joke.
Low-quality tool contacts risk getting melted plastic on your tool.
Measured capacity is 3.85Ah, less than half of the 8.0Ah claim.
Solid power delivery, but the plastic around the tool contacts will melt with extended use.
No safety features and shoddy electric current routing.

Capacity Test
We measure the amount of usable energy the pack supplies from 100% to 0% charge.
Pack Internal Resistance Test
Failure Test
The battery is stepped through 30s at increasing current levels, ignoring safety features like temperature and voltage warnings, until the pack fails catastrophically.
