LIDAIAX 2 Pack True 6.0Ah Capacity Lithium Ion Replacement Battery
Tier Bby LIDAIAX
Test published May 2026
This battery is not for high-power applications, but it's absolutely solid. Fantastic construction, relatively honest about its stated capacity, and no safety issues. Nearly identical to the xiuqiyu and Menssda packs, their low-current cells cannot sustain saw-level power output, but they are ideal packs for drill/impact driver use. Upgrade the cells and these become S/A-tier.
