MENSSDA True 6AH Capacity Replacement Battery
Tier Bby MENSSDA
This battery is not for high-power applications, but it's absolutely solid. Fantastic construction, actually exceeds its stated capacity, and no safety issues. Nearly identical to the Lidaiax and xiuqiyu 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.
