Tier Fby Eagglew
Decent performance across the board, but dangerous behavior and unknown cell origin make this a no-go.

Actual capacity is 3.2 Ah, vs advertised 12 Ah. Complete lie.
Decent tool contacts and otherwise solid electrical and mechanical construction.
3.2 Ah is not good.
Middle-of-the-tier-list performance; but a cell exploded under normal operation.
A cell vented (a minor explosion) during the performance test, which should be within the "operation as usual" envelope.
Testing Statistics
Cell notes
No credible manufacturing data found. Potentially part of RJLD / Jiangsu Runjin Lithium Battery.
Cycling Test
We cycle the batteries at high-power (800W for 20s on, then 20W for 6s off) to reflect their actual usage in high-load scenarios like circular saw use.
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.
