Chose 30T for higher discharge. 35A vs 25A makes a difference in my power tools. Worth the slight capacity trade-off.
Samsung 30T is the gold standard for 35A applications. This 10-pack is the best way to buy them.
500 cycles in, still 95% capacity. Samsung durability is impressive for cells pushed this hard.
35A continuous from a 21700 is incredible. Built a drill pack that outperforms OEM. Samsung quality is unmatched.
My Emisar D4SV2 on turbo is insane with these. 35A delivers maximum lumens. Samsung 30T is the best.
